The only publications of one of the earliest scientific societies, active from 1664 to 1672. Founded by Gerard Blaes, and numbering Jan Swammerdam among its members, the college devoted itself to comparative anatomical and physiological investigations of the lower vertebrates, concentrating primarily on fishes and mammals. The above works contain the first publication of Swammerdam’s early experiments with neuro-muscular physiology. Other portions of the works were probably written by Blaes.

The "first comprehensive manual of comparative anatomy based on the original and literary researches of a working anatomist. Blasius's observation on human anatomy are followed by eighty five pages devoted to the anatomy of the dog. Regarding the anatomy of dog (Anatome Canis, pages 168 to 252), this is the first comprehensive and original treatise on a verterbrate since the publication of Ruini's volume on the horse in 1598" (Cole).

“The first comprehensive manual of comparative anatomy based on the original and literary researches of a working anatomist” (Cole). Blaes anticipated Cowper in finding the Cowper’s glands, which he illustrated in his plate of the genitalia and os penis of the rat. The 85 pages devoted to the anatomy of the dog was the first comprehensive and original treatise on a vertebrate since Ruini (No. 285).

Blasius first published much of the material in this work, including the treatise on the anatomy of the dog, in his ‎Miscellanea anatomica, hominis, brutorumque variorum, fabricam diversam magna parte exhibentia‎ (Amsterdam: Caspar Commelin, 1673.). In that work the Anatome canis appeared on pp. 168-252. Other material previously appeared in Blasius's Observata anatomica in homine, simia, equo, virtulo, ovo....(Leiden, 1674).
