quite valuable, but cannot be displayed to advantage for want of 

 room. There are a number of specimens in the collection not to 

 be found in any other, and are therefore too valuable to be exposed 

 in a building that is not absolutely fire-proof.

REPORT OF THE CURATOR OF MICROSCOPY. 



Since April, 1886, two exhibitions of microscopical objects 

 and apparatus have been given by the society. One on the 30th 

 of May, a general exhibition, and an exhibition of histological 

 preparations on the 2nd of October. Several meetings were held 

 for the purpose of forming a section of microscopy, but without 

 effecting an organization. This is especially unfortunate, as one 

 of the prime objects of this society is the study of the Natural 

 History of our immediate vicinity. Our students of the higher 

 animals and plants have, in cataloguing at least, left comparatively 

 little to be done, but next lo nothing is known of the microscopic 

 fauna and flora of our neighborhood. 



During the past year the following preparations have been 

 added to the collection of the department: Two slides of diatoms, 

 a section of peccary hair and a preparation of so-called volcanic 

 ashes. Respectfully submitted, 



Geor(;e B. TwrrcHELL. 



REPORT OF THE CURATOR OF CONCHOLOGY. 



During the past year four hundred species and varieties, known 

 as the Hemphill Collection, have been catalogued and placed in 

 cases. This collection was purchased and received previous to 

 the last annual meeting of this society, but owing to a lack of case 

 room was not uni)acked. Even now it is not in proper conditipn, 

 but in cases belonging to another department. A number of fine 

 'exchanges have been made ; one with Mr. T. H. Aldrich o^ 

 thirty-two species, another consisting of forty species with Mr. H. 

 E. Dore, of Portland, Oregon, and still another with Mr. Arturo 

 Bofill, of Barcelona, Spain, numbering one hundred and forty 

 species. Mr. Aldrich also presented a number of species, ard a 

 large donation of two hundred and twenty-one species was received 

 from Mr. Charles Faber.
