An essay concerning nutrition in animals. Proving it analogical to that of plants. And discovering the like structure and use of the organs to be alike in both. With many observations towards the practise of physick. Together with a short discourse upon the nature of the soul in plants, animals, and man. Offered to philosophers and physicians, in order to clear difficulties, in the oeconomy of animal bodies, and applications of remedies. By Philip Guide, M.D. & Col. M.L.L.
