78 Forty-sixth Report on the 



lections of the Lamellibranchiata. These are ready for incorpo- 

 ration into any general school collections which may be ordered 

 by the Kegents. This work required the selection, arranging 

 and recording of about 1,750 specimens, besides the handling of 

 at least six times as many more specimens, in the selection of 

 these collections. Each one of these collections is accompanied 

 by a catalogue giving the generic and specific names of the fos- 

 sils. A great deal of miscellaneous work has been necessary in 

 accomplishing the result above stated which is of such a nature 

 that it can not be recorded, but which has nevertheless occupied 

 time. 



Mr. William F. Cooper, my private assistant, has selected from 

 the duplicate collections of the several geological formations 

 about twelve hundred specimens, for the Plattsburgh iN'ormal 

 School, which await my examination and revision before being 

 catalogued. This work I expect to be able to do before the first 

 of January. 



During the year past 48 boxes of spiscimens have been sent in 

 from the Livonia salt shaft. These have all been opened and the 

 specimens cleaned, ticketed and recorded. Such specimens as 

 were especially required for the Museum collections have been 

 selected and arranged in drawers which are accessible. The col- 

 lection has furnished a considerable number of new species of 

 fossils which will at some future time be described and published, 

 and will add to our knowledge of the faunas of the formations 

 passed through in the shaft. The detailed account of the rocks 

 passed through in sinking the shaft will be given under another 

 head, with such other information as may be connected 

 therewith. 



At the same time part of the collection for the Batavia Institu- 

 tion for the Blind has been selected, and attention will be given 

 to its completion before the first of January. 



The employment of Mr. Emmons by authority of the secretary 

 of the regents, upon the duplicate collections, will secure the 

 distribution and arrangement of a large amount of material into 

 school sets and for preservation in the Museum collections. If 

 his services shall be continued for the coming year we shall have 

 a larger amount of material prepared and ready for distribution 

 into school collections.
