which she had a first-cross calf. The following season, the same 

 cow was served with a pure Aberdeenshire bull : the produce 

 was a cross calf; which, when two years old, had very long horns, 

 the parents being both polled. Again, a pure Aberdeenshire 

 cow was served, in 1845, with a cross bull, that is to say, an 

 animal produced between a first-cross cow and a pure Teeswater 

 bull. To this bull she had a cross calf. Next season she was 

 served with a pure Aberdeenshire bull : the produce was quite a 

 cross in shape and color. 



"3. With regard to the Dog, it has often been observed, 

 and, indeed, it seems to be matter of notoriety, that a well bred 

 bitch, if she have been impregnated by a mongrel dog, will not, 

 although lined subsequently by a pure dog, bear thorough bred 

 puppies ever after, or at least in the next two or three litters. 

 And it appears farther, that the progeny are affected in respect, 

 not merely of their shape and color, but of their natural instinct 

 also. A pure Terrier bitch, (of the Skye breed,) of a dark brown 

 color, with red legs, was lined the first and second time she came 

 in season, by one and the self-same dog — a mongrel cur, — and 

 produced in the first litter four, and in the second, three puppies, 

 all of which took very decidedly after the cur, which was black, 

 with rod legs and white feet. On the third occasion she was 

 lined by a pure dog (of a grey color) of exactly the same breed 

 as herself; and, in order that no other might have access to her, 

 she was locked up with this dog the whole time her heat lasted. 

 The issue was two puppies, both of which bore the closest 

 possible resemblance to the cur, in color, shape, and appearance 

 generally. 



" 4. The like occurrence has been observed in respect to the 

 Pig. A sow of the black-and-white breed, (known as Mr. 

 "Western's breed,) belonging to Mr. Giles, became pregnant by a 

 boar of the wild breed, of a doep chestnut color. The pigs pro- 

 duced were duly mixed, the color of the boar being in some of
