Considering that part of the family 

 following Patrician and Iris, both of 

 whom were champions, all white, and 

 over 35 lbs., the former having a general 

 record of approximately one marked dog 

 per litter and the latter having a tendency 

 to mider pigmentation, we have Fig. 16 

 to which the following description 

 applies.

In conclusion the writer offers this 

 collection of data as a contribution 

 toward what he believes would be an 

 interesting study, i. e., the genealogical 

 tendencies of the Bull Terrier, a breed 

 requiring extremely marked and some- 

 what antagonistic characteristics.

Men and Rats Learn in the Same Way 



An attempt to compare human and 

 animal learning has been made by L. A. 

 Pechstein (Psychol. Monogs., No. 2, 

 1917). He has taken the results of 

 tests made on men and on rats recently 



by experimental psychologists and 

 compared them by statistical methods. 

 His conclusion is that "there is no 

 royal road to mastery for the human 

 not open to the rat."
