tion, which contained several species of Foraminiferge or 

 Diatomacege, and which had been identified by Prof. Bailey 

 himself, are entered in a separate book, entitled " The Cata« 

 logue of the Bailey Microscopical Slides." These .slides are 

 registered under the same numbers as in the current cata- 

 logue, but instead of only one line devoted to a general de- 

 scription and name of the locality, the space of half a page 

 or more is devoted to the list of the species found upon that 

 particular slide, together with the marks and measurements 

 for finding each specimen. Prof. Bailey had begun this cata- 

 logue by registering 793 slides in this manner on foolscap 

 paper, and this was continued by Miss Washburn. 1391 

 slides were entered in a similar manner by this lady upon 

 loose sheets of foolscap paper. The original notes of Prof. 

 Bailey, contained upon slips of paper usually loosely wrapped 

 around the slide, were faithfully transcribed, and the originals 

 filed away for preservation. The whole, amounting to 372 

 sheets of foolscap, has been substantially bound, and is now 

 available for reference. 



The microscopical collections have also been greatly en- 

 riched during the past year by a collection of 477 slides, pre- 

 pared by the late Wm. Glen, formerly Preparator at the 

 Museum of Comparative Zoology, Cambridge. These were 

 purchased and given to the Society by Mr. R. C. Greenleaf 

 and Dr. A. D. Sinclair. The Society owes its thanks to 

 these gentlemen, not only for the value of the gift, but for 

 the admirable condition in which the slides had been pre- 

 served, and the substantially bound catalogue prepared by 

 Mr. Greenleaf. 



The Glen Collection is especially rich in sections of the 

 spines of Echini and the tongues of Mollusks, and also con- 

 tains a large number of miscellaneous preparations. 



Including this accession, the Society's collection contains, 

 exclusive of the duplicate material already picked out, 3356 

 slides and preparations. 



The collections of Corals and Echinoderms are now being
