Mead performed numerous experiments, including tests with viper venom which lead to his book on poisons. His book describes their effects on the body in accordance with the precepts of the Iatrophysical School, which claimed that all physiologic and pathologic phenomena were the result of the laws of physics.

Mead formulated the position that periodic atmospheric tides arising from planetary forces produced alterations of gravity, elasticity, and air pressure; these changes, he argued, affected the human body in health and disease. Mesmer's disseration, which originated animal magnetism, was largely a plagiarism of Mead's work. Translated into English by Thomas Stack "under the author's inspection" as A treatise concerning the influence of the sun and moon upon human bodies, and the diseases thereby produced (London, 1748).

In 1719 Mead was asked for advice concerning an outbreak of plague in Marseilles, and replied with the above tract of 59 pages, which has been called the first epidemiological report produced by a physician at the command of the state. It underwent seven editions in one year. By the eighth edition (1722) Mead expanded it into a book of 150 pages. Mead concluded that isolation of the sick is more effective in stopping the spread of infection than general quarantine or fumigation. The book has been called almost a prophecy of what was to develop as the English public health system.

Includes a Latin translation of Rhazes’s commentary on smallpox. Mead favored inoculation, and his great authority and influence contributed to a more general acceptance of this measure. English translation entitled A discourse on the small pox and measles, London, 1748.

Mead's library consisted of upwards of 10,000  printed volumes, and many rare and valuable manuscripts. The collection was especially rich in medical works, and in early editions of the classics; it realized over £5,500 in a sale that lasted no fewer than 28 days. Mead was also a collector of classical antiquities, paintings, coins, and medals. His art collections, including several Rembrandts, realized £10,550.
