VIRILE SENTIMENT 79 



regard to a qualitative result, how far is the ex- 

 pectation similarly corroborated by a quantitative 

 result ? The Mendelian expectation with regard to 

 the proportion of albinoes and normal individuals is 

 as 1 : 3. The total number of offspring concerned 

 for purposes of calculation is twenty-four plus a few 

 normals, the number of which is not recorded. The 

 expectation, therefore, in round numbers is six 

 albinoes and eighteen normals. The actual number 

 is eight albinoes and sixteen normals. There is thus 

 what the prediction requires, a large excess of normals 

 over albinoes. And when we bear in mind that a 

 few more normals, who are known to have existed, 

 must be added to the actual result, we see how well 

 result and prediction meet each other. 



Dr. A. M. Gossage has quite recently made a study 

 of some previously recorded cases of hereditary 

 transmission of pathological characters in man, and 

 he has produced a number of interesting facts. On 

 the whole the cases which he has studied and re- 

 published confirm the Mendelian generalisation, 

 though there are some exceptions which are discordant 

 with it. These latter may, however, receive an 

 adequate explanation when we know more of the 

 particular diseases with which they are connected, 

 or when we have been able to investigate a larger 

 number of similar cases. But it seems quite clear 

 from his survey of cases that segregation of alter- 

 native characters, such as some pathological trait 

 and normality, does occur. The crucial test that such 

 segregation has actually occurred is to be found in
