So far as concerns Science and Medicine, an 

 attempt is made to answer the question by the col- 

 lection of a Bibliotheca Prima, examples from 

 which are here shown. The idea is to have in a 

 comparatively small number of works the essential 

 literature grouped about the men of the first rank, 

 arranged in chronological order. 



I have put out the editiones principes of twenty 

 of such works. The fundamental contribution may 

 be represented by a great Aldine edition, e.g. Aris- 

 totle, by the brief communication such as that of 

 Darwin and Wallace in the Proceedings of the 

 Linnean Society, 1858, or by a three-page pam- 

 phlet of Roentgen. From the card lists of Galen, 

 Hippocrates, Vesalius, and Harvey, those inter- 

 ested will see the aim and scope of the collection. 



The works on exhibition are :
