166 TRANSACTIONS OF SCIENTIFIC SECTION. 



former, and the scientific works which form the larger 

 portion of the latter, are collected by, and practically be- 

 long to, the work of our Section, justifies me in includ- 

 ing a few words in regard to them in this report. A 

 large number of specimens have been acquired in the 

 museum, both by donation and purchase, thus adding 

 much to bur opportunities for comparison and study. 

 The most valuable of these is the white shark (Carcha- 

 rodon car char ias), the skin of which, with that of its 

 companion, the sand shark, were presented to the In- 

 stitute by Doctor Stevenson. Many valuable scientific 

 treatises have been placed on the shelves of our library 

 this year. One of the most valuable of these are the 

 volumes on tk Infusoria," by W. Saville Kent. It is an 

 elegant and expensive book, acquired by purchase, and 

 those who possess microscopes will find it to their advan- 

 tage to consult this book in their examination of infu- 

 sorial organisms. 



In conclusion, I would thank the members of the Sec- 

 tion for the most cordial and effectual way in which 

 they have cooperated with their chairman in making the 

 record of the present season one of which we have no 

 reason to be ashamed.
