THE LIBRAkY. 49 



SECTION 1. STUDIES OF FIRST YEAR. 



As has been stated, the studies during the first year of 

 the professional course relate to Topography, Integral and 

 Differential Calculus, Descriptive Geometry, Applied 

 Mathematics and Applied Chemistry. 



Sub-Section 1. Applied Mathematics. 



In the Library there were 6 works on subjects pertaining 

 to Mathematics, 218 on Pure Mathematics, and 435 on 

 Mixed and Applied Mathematics j in all, 1015 volumes. 



Sub Section 2. Applied Chemistry. 



Amongst subjects to which attention is given in the 

 study of applied chemistry is Tannin. 



A good illustration of the mode and exhaustive character 

 of the instruction given in Applied Chemistry is supplied by 

 a treatise on Tannin by Professor Don Carlos Castel, which is 

 at the command of the students. The subject in this is thus 

 stated : To determine the intrinsic value of the tannin or 

 astringent substances pertaining to tannin, produced by 

 the vegetables of five or more of the province of Spain, 

 and in regard to each to state with the nearest approxima- 

 tion attainable, the age of the plant, and thereafter its 

 growth, habitat, seasons of the year most favourable for 

 the collecting of the produce, and the routes or means of 

 export or transport of this to market ; a treatise adopted 

 by the Royal Academy of Exact Physical and Natural 

 Sciences at their annual meeting in 187G. 



In the introduction to this treatise, citing words with 

 which M. J. Pelouse in 1833 opens his valuable work on tan- 

 nin and its sources, to the effect that there is no organic sub- 

 stance, in regard to which there have been so many enquiries, 

 and yet in regard to which the history is so greatly desid- 

 erated Senor Castel cursorally reviews what had been done 

 by chemists in different countries during the forty years pre-
