MEASUREMENTS AND WEIGHTS OF SEALS. 7 



on the second visit to the Pribilof than it was on the first, and I am under obligations 

 to Mr. J. O. Eedpath for calling my attention to various distinguishing features. The 

 opinion of the natives is of little value, and with them the question undeniably 

 resolves itself into a mental sorting of the killable seals into various classes. That 

 definite age characters do exist is fairly well shown by the agreement in measurements 

 between seals selected at different times by Mr. Eedpath and myself as 3 and 4 year 

 olds, the selection in my own case being based on the condition of the canines, 

 whiskers, and wig. Of course, there is an overlapping of seals from the fact that the 

 small 4-year-olds, for example, will be of the same size as the large 3-year-olds, but 

 here the condition of the teeth, flippers, and whiskers will usually show clearly which 

 are the older.
