E WART'S PENYCUIK EXPERIMENTS 



But such cases have a practical rather than a theoretical interest ; 

 they hardly touch the problems of heredity or evolution. 



On a priori grounds, the probabilities are strongly against the 

 occurrence of telegony, but there is no foothold except in the experi- 

 mental test, and that is what Professor Evvart has given us. 



The general nature of the experiments is well known, and for the 

 interesting details the book and its beautiful pictures must be con- 

 sulted. It may suffice to mention one of the best cases. A Rum

pony mare, Mulatto, was served by the Burchell zebra stallion 

 Matopo, and the result was Romulus, with markings quite different 

 from those of his sire, but suggestive rather of the Somali type. In 

 1897 Mulatto had a bay colt foal to a gray Arab stallion, and this 

 foal — unfortunately short-lived — gave no proof of telegony. The 

 stripes which most frequently occur in horses were absent ; there were 

 others which are not uncommon in horses ; but the most distinct 

 markings (not that any were strongly developed), namely, those across 

 the croup, were of a sort extremely rare in both foals and horses. In 

 short, the marking of Mulatto's second foal is puzzling, but in no definite
