ZOOLOGY. 387 



Souncungs, including; two boxes from Lieut. Berryman's Soundings between 

 America and Ireland, in 1856. 



Three boxes contain specimens from Soundings in the Arctic and Pacific 

 Oceans, Gulf of Mexico, and Para River, etc , in South America. 



In four boxes are American and Foreign Diatoms; Diatoms in Guano; 

 and Fossil Polvcistins and Diatoms from Barbadoes. 



it 



In three boxes arc Fossil Diatoms from Virginia and Maryland ; Ber- 

 muda, Monterey, California, Suissun Bay, etc. 



Nearly all the specimens in the above boxes were mounted by Professor 

 Bailey ; and they are accompanied by manuscript catalogues, or by memo- 

 randa on slips of paper, in which the positions of more than three thousand 

 individual objects on the slides are noted with reference to Bailey's Univer- 

 sal Indicator for Microscopes ; thus enabling the actual specimens described 

 by him to be readily found and identified at any future time. A part of the 

 collection is also accompanied by an alphabetic catalogue of species, with 

 reference to the slides on which specimens may be found. 



Two boxes contain recent and fossil Vegetable Tissues ; and two others 

 Test Objects and miscellaneous organic bodies, and a micrometer scale on a 

 glass slide. 



The number of glass slides in these twenty-one boxes is five hundred and 

 fifty. 



In addition to the selected specimens in the Microscopic Collection, there 

 are more than eight hundred specimens mounted on glass slides, comprising 

 many duplicates of those in the collection, and a variety of miscellaneous 

 microscopic objects. 



There arc also two hundred specimens of Polythalamia mounted as 

 opaqus objests and labelled. These are not duplicates of the Polythalamia in 

 the Microscopic Collection, which are in Canada balsam. 



A very valuable portion of the bequest consists of the original specimens 

 of microscopic material, collected by various scientific and exploring ex- 

 peditions, and an extensive scries of specimens received from European 

 correspondents, including Ehrenberg and other distinguished microscopists. 



The Alga3 are contained in thirty-two portfolios". They are from almost 

 every part of the globe. They are arranged and named in a manner to 

 afford great assistance to the student, who may be interested in the study of 

 marine botany. In most instances, specimens of the same kind, but collected 

 at different seasons of the year, or brought from different localities, and pre- 

 senting different appearances to the naked eye, arc placed side by side upon 

 the same sheet, or within the same envelop, so that the work of comparing 

 one specimen with another, and of ascertaining the names of doubtful ones, 

 which the student may possess, is rendered easy. The whole number of 

 specimens in this department of the collection is about four thousand five 

 hundred. Of this number nearly one half belong to the family Florida:, and 

 comprise about two hundred varieties. 



The collection also includes sixty-nine specimens of animal tissues, of ver- 

 tebrata, articulata inollusca and radiata. 



The whole number of books belonging to the collection is eighty-four,
