Musaeum Regalis Societatis, or a catalogue and description of the natural and artificial rarities belonging to the Royal Society and preserved at Gresham College. Whereunto is subjoyned the comparative anatomy of stomachs and guts.

Grew, secretary to the Royal Society, compiled this illustrated catalogue of its museum, then housed at Gresham College. Published with the catalogue is Grew’s study of the stomach organs, which is the first zoological book to have the term “comparative anatomy” on the title page, and also the first attempt to deal with one system of organs only by the comparative method.
