Eicubaum, F. On the Cranial Capacity of Horses. Archiv fur 
Thierheilkunde. 
The author gives the capacity of the Arabian horse as 712 cub. c.m., 
Russian 720, and Belgian 768. He finds (1) that the cranial part of the 
skull is more developed in proportion to the facial in eastern than in 
western (European) horses ; and (2) that the breadth of the skull of 
eastern is greater in proportion to length than in western horses. [Not

The author shows (1) that the different colours of horses are a result 
of domestication ; (2) that when the parents are of similar colours the 
foals have the same colour in four out of five cases, and that when the 
parents are of different colours the foals have that of one or the other 
in about one-half of the cases observed ; (3) that white and brown are 
more certainly transmitted than are any other colours ; (4) that foals 
rather more often resemble the mother than the father in colour, especially 
when the former is black. In a second part of his paper the author works 
out the influence of the age of the parents upon the sex of the foals, and
