the ribs, so that the hind legs lay upon the neck and upper part 
of the shoulders, while the fore legs took a direction upwards, em-

they and the head were encircled. The head was deeply bent

We are much obliged to Mr. Bull for this case of monstrosity, 
and the very satisfactory drawing by which it was accompanied. 
There are, however, on record descriptions of other mis-shapen 
foetal growths very singularly resembling this. Professor Dick 
describes one which occurred in the practice of Mr. Tennant, of 
Ravenstrather, N. B. “ A cow had calved ; she had usually 
produced twin calves, and it was suspected that she had still 
another calf in the womb. On introducing the hand, Mr. Ten-
