VI. The committee agrees, that whatever may 

 be the ultimate ruling on the last point, there are 

 many practical difficulties in the way of recog- 

 nizing names proposed as in case 2, so that even 

 were such names held to be available, many of 

 them would have to be rejected as of uncertain 

 application. It is perfectly clear that no rules 

 will absolve an author from using his critical 

 judgment in the several cases that come before 

 him; and after the rules have declared a name 

 available from their standpoint, it may be a long 

 way to availability from the standpoint of prac- 

 tical identification. 



The committee is greatly indebted to Dr. C. W. 

 Stiles, the secretary of the International Com- 

 mission on Zoological Nomenclature, for a full 

 and luminous discussion of the matters in dispute.

THE MICHIGAN ACADEMY OF SCIENCE 



The 15th annual meeting of the academy was 

 held at Ann Arbor, Mich., March 31 and April 

 1 and 2. The meeting was made the occasion of 

 a Darwin Centenary Celebration, and the Research 

 Club of the University of Michigan and the Mich- 

 igan Schoolmasters' Club cooperated with the 

 academy in furnishing special programs. The 

 papers presented were as follows:
