Moss showed that the blood of all individuals could be placed into one of four groups. His classification has been the one most commonly used until recently. The work was similar to that of Janský and completed before the writer learned of the latter’s publication.

Price-Jones described a method for the direct measurement of red blood cells, which led to the term, “Price-Jones curve”. See also his book, Red blood cell diameters, London, 1933.

Keith, Rowntree, and Geraghty devised a method for determination of plasma and blood volume, which includes the injection of a dye.

Boyle showed the effects of the elasticity, compressibility, and weight of air. He investigated the function of air in respiration, combustion, and conveyance of sound. Most significantly Boyle demonstrated that air is essential for life.

Discovery of the capillary circulation. Malpighi demonstrated that the pulmonary tissues are vesicular in nature and showed that the trachea ends in bronchial filaments. His De pulmonibus includes his demonstration of the capillary anastomosis between arteries and veins. This book, which is very rare, consists of two letters to Borelli describing observations made through the microscope on the lung of a living frog. In the second letter Malpighi described small channels connecting arteries with veins, the capillaries. This was the first proof that blood circulation occurred within a closed hydraulic system. The second edition was published as an appendix to Thomas Bartholin’s De pulmonum substantia et motu diatribe, 1663. It is republished in his Opera omnia, Lugduni Batavorum, 1687, ii, 331. A facsimile was published in Milan in 1958; English translation by J. Young in Proc. roy. Soc. Med., 1929-30, Sect. Hist. Med., 23, 1-11. See No. 915

By blowing air from a bellows over the exposed lungs of a dog, Hooke proved that respiratory motion is not necessary to maintain life, but that the essential feature of respiration lies in certain blood changes in the lungs. Reprinted in J. F. Fulton’s Selected readings in the history of physiology, 2nded., 1966, pp. 121-23.

First investigation of the action of the intercostal muscles in respiration.

"Recent data on intercostal muscle function, largely electromyographic, tend to confirm the ideas of Hamberger, who, in 1748 (recte 1727), proposed a theory of intercostals muscle action upon the rib cage. Hamberger's scheme was based upon a consideration of the ribs as levers and the vertebral column and sternum as fulcra, and of the directions in which the internal and external intercostal muscle fibers ran. He proposed that the external intercostals were inspiratory and that the internal intercostals were expiratory, except in the parasternal regions where the internal intercostals (there are no other intercostal muscles) are inspiratory. Careful selective electromyographic studies in both animals and man (using small bipolar needle electrodes) by Draper et al, Taylor et al, and Sears et al have amply confirmed Hamberger's ideas" (John T. Sharp., et al., "Respiratory Muscle Function and the Use of Respiratory Muscle Electromyography in the Evaluation of Respiratory Regulation", Chest, 70 [1976], 150).

(Prior editions of this bibliography incorrectly cited the third edition of 1748 for this discovery.)

Isolation of carbon dioxide. English translation, Minneapolis, 1973.

The isolation of oxygen was first achieved by Priestley. He also demonstrated that plants immersed in water give off oxygen and that this gas is essential for animal life.

Discovery of nitrogen.

Although Priestley isolated oxygen, it was Lavoisier who discovered its real significance. He showed the true nature of the interchange of gases in the lungs and exploded Stahl’s phlogiston theory. Lavoisier was guillotined during the French Revolution.

Cavendish isolated hydrogen in 1766, and later demonstrated the composition of air.

Hassenfratz, a pupil of Lagrange, maintained that the oxidation of carbon and hydrogen took place in the blood, and not in the lungs as taught by others.

In 1804 the Berlin Akademie der Naturwissenschaften offered a prize for the best essay on the structure and function of the lungs. The prize was won by Reisseisen, while Soemmerring received honorable mention. The texts of both works were published in one volume; Soemmerring’s essay was entitled “Ueber die Structur, die Verrichtung und den Gebrauch der Lungen”. Digital facsimile from Google Books at this link.

Le Gallois described the action of the vagus nerve on respiration. He showed that bilateral section of the vagus can produce fatal bronchopneumonia. The above work includes (p. 37) his location of the respiratory center in the medulla , and not in the spinal cord, as had been previously believed. “For the first time, an area of brain substance within a major subdivision of the brain and having a specific function had been defined accurately by experiment” (Clarke & Jacyna).

Le Gallois is also remembered for his reviving, after Borelli, the neurogenic theory of the heart’s action; namely that the motor power of the heart comes from the spinal cord via branches of the sympathetic nerves. Le Gallois also developed a primitive isolated heart-lung preparation in rabbits and was the first to suggest the possibility of a heart-lung machine: “If the place of the heart could be supplied by injection, and if, for the regular continuance of this injection, there could be furnished a quantity of arterial blood, whether natural or artifcially formed . . . then life might be indefnitely maintained” (quoted in Fye, “Julien Jean César Legallois,” Clinical Cardiology 18 (1995): 599-600. .

Nancrede (Philadelphia, 1813) as Experiments on the principle of life, and particularly on the principle of the motions of the heart, and on the seat of this principle: including the report made to the first class of the Institute, upon the experiments relative to the motions of the heart. Digital facsimile from the Medical Heritage Library, Internet Archive at this link.

First quantitative analysis of the blood gases. Magnus proved that the arterial blood contains a higher concentration of oxygen than venous blood and that the latter had a higher carbon dioxide content.

Invention of the spirometer, making possible the determination of the vital capacity of the lungs. Hutchinson used the spirometer while evaluating candidates for life insurance as a physician for Brittania Life.  Particularly, he researched the safety of coal mining and the presence of charcoal in miner's lungs. He also theorized that air pollution could lead to poor health. Hutchinson’s work first appeared in summary form in Lancet, 1844, 1, 390-391, 567-70.

Jourdanet’s observational work in remote areas of Latin America and Asia produced important evidence for Bert’s proof that altitude sickness is due to anoxemia. In La pression barométrique (No. 944) Bert described how Jourdanet made it possible for him to do his laboratory work on altitude physiology, and how the two agreed to each take half the field: Bert, the laboratory work; and Jourdanet, the observational. Bert also credits Jourdanet with the theory of anoxemia. Extensively illustrated. Second edition, 2 vols., 1876. See No. 935.2. Digital facsimile of the 1875 edition from the Internet Archive at this link.

The most famous work in the history of altitude physiology, in which Bert proved that the principal symptoms of altitude sickness arise from reduced partial pressure of oxygen and not from diminution of total pressure. Bert introduced oxygen apparatus to avert the dangerous consequences of ascent to high altitudes, and was the first to study the conditions of high-altitude ascents in a pressure chamber. He also explained the etiology and mechanism of caisson disease. English translation, 1943. See No. 12192.

Full English translation from 2nd ed. (1671), London, 1676.

This is primarily a work on the poisonous water hemlock, its dangerous effects, its medicinal uses, and antidotes to counter the poison. However, it also contains the first description of the tiny glands in the mucosa of the duodenum, now called Brunner’s glands. Brunner was the author’s father-in-law; however, Wepfer first described them in this work. "They are described in the summary of an experiment on a dog, on pages 206 and 207. Parts of the book contains letters or extracts of letters between Wepfer and other toxicologists of that era. Four engraved plates illustrate one species of the hemlock family, the roots and lower stalk, the branching stalks, the leaves and the flowers and seeds. ... Wepfer systematically studied poisons, with particular attention to the toxic water hemlocks. He was the first to analyze the pharmacological effects of coniine, an alkaloid of hemlock that was not isolated until much later; and his classic description of hemlock poisoning was often cited as the standard" (Heirs of Hippocrates 535.5).

Using a pet buzzard, de Réaumur succeeded in isolating the gastric juice and demonstrating its solvent effect on foods.

First isolation of human gastric juice. Stevens was also the first successfully to perform an in vitro digestion, proving the presence in the gastric juice of the active principle necessary for the assimilation of food. An English translation is included in Spallanzani’s Dissertations relative to the natural history of animals, 1784, vol. 1, pp. 303-16.

With a complete translation of his inaugural dissertation De alimentorum concoctione...Edited by Stacey B. Day. Montreal, 1969.

From the Wikipedia article on Edward Stevens, accessed 01-2017:

"Stevens was born in St. Croix in the Virgin Islands. Stevens's father, the merchant Thomas Stevens,^[1] would also become the adoptive father of an orphaned Alexander Hamilton.^[2] According to Ron Chernow's Alexander Hamilton,^[3]people would often say that Edward Stevens and Hamilton looked like brothers. Secretary of State Timothy Pickering, who knew both men in adulthood, noted that the men were strikingly similar in appearance and concluded that they must be brothers. Ron Chernow says many aspects of Hamilton's biography make more sense given Stevens's paternity. It would explain why Hamilton was adopted into the Stevens family while his brother, James, was not. It may have also been a factor in Hamilton's supposed father abandoning his family.^[4]"

In the first patrt of this work, Della digestione dissertazione prima Spallanzani confirmed earlier doctrines of the solvent property of the gastric juice and discovered the action of the saliva in digestion. He stated that gastric juice can act outside the body and can prevent or inhibit putrefaction. He obtained gastric juice by tying a sponge on a piece of string, then allowing it to be swallowed. The second part contains Spallanzani's experimental researches on reproduction in animals and plants in which he demonstrated the role of seminal fluid in generation. The second part also includes his investigations into artifical fertilization, in which he recorded the first case of artificial insemination in a viviparous animal.

Young, one of the first American experimental physiologists, showed the solvent principle in the gastric juice to be an acid, but wrongly inferred that it was phosphoric acid. He also deduced the association and synchrony between gastric juice and saliva. Reprinted, Urbana, Ill., 1959.

Includes description of “Hesselbach’s hernia” and “triangle”. He wrote a further volume on the subject in 1814.

“Meckel’s diverticulum”.

Physiologists still consult Magendie’s classic description of the physiology of deglutition and vomiting. Magendie proved, against the current theory of Haller, that the stomach was passive rather than active in vomiting. This was essentially correct; however Magendie did fail to observe the active role of the plyloric end of the stomach. English translation in Ann. Phil., London, 1813, 1, 429-38.

Magendie showed that the epiglottis is not necessary for swallowing, which disproved the accepted doctrine that the epiglottis was necessary to cover the glottis to prevent food from entering the trachea.

Before turning to surgery, Brodie did important work in physiology. Above is his study of the influence of the pneumogastric nerve on gastric secretion.
