THE GENERAL SUBJECT.

From the results of a very large series of experiments in crossing 
variously coloured varieties of Rats, Hamsters, &c., the author finds the 
influence of the male to predominate. When two different varieties are 
paired an uncertain proportion of melanism appears in the offspring. The 
production of young of an intermediate colouration is regarded as showing 
the specific distinction of the parents.
