 by laiJaakftiniini He reviewed the relative 



to mankind and the 

 p mental and moral faculties 

 eaQsd into play by the study of the more eiact 

 and leaf eiact sciences, assigning a high place to 

 logic, methemelioi. and phvaics. In conclusion 

 he eaaimed up the peculiar characteristics of 

 Ike science of mathematics as follows: - It is 

 mfane in the cosmic nature and t h. universality 

 of tie qnesUons it deals with, in the stability of 

 th data on which it rests, on the reliableness of 

 tae assistsnni it renders to every other science 

 which bat become sufficiently highly generalized

 ttics is a branch of logics or 

 of mathematics. If we group 

 or the moment we may say that 

 they are~furt her unique in the almost inconceiv- 

 able etactness of tUr methods and in their 

 being eielusively an intellectual product as 

 omnsed to a combined intellectual and observa- 

 tional one. It may be added that, notwithstand- 

 ing the purely intellectual nature of the subject, 

 ithetandtng the highly general nature of 

 of its results, the mere volume of these re- 

 . as hi so many other sciences, is so great 

 that it is impossible now for a single man to be 

 really conversant with any but a small j 

 of the whole. The prospects opened up to the 

 riaftfo met liomsricisn. however great 

 in that direction are far more than

 to him who would walk where no

 in that mathematics from its very 

 linn i provides more points of contact of the 

 own and unknown than in any former age."

 is a mighty list. Surely no chemi>t desirous of 

 taking up original research can complain of the 

 variety of work presented to his choice. If any 

 of the suggestions I have made or the pleas for 

 research 1 have put forward should lead chem-
