Witson—WHendelian Characters among Short-horn Cattle. 321 
The table of coat-colours on page 318 ought therefore to be 
reconstructed on the basis that the Saxon “reds” are one of the 
ancestral races, and the Roman white cattle the other. ‘he table 
then becomes as follows :—

accuracy; but the discrepancies can be explained. They are the 
result of three causes, viz. :— 
(a) Sometimes it requires a close examination to tell whether 
a calf is really red or roan. Breeders have not hitherto examined
