Particular Variety of Bull. 



oval, or 

 with the 



one half above the orbit, and bearing a resem- 

 blance to a cup and ball, thus enabling the ani- 

 mal to see on all sides with equal ease. The 49 

 iris is naturally of a pale blue colour; but, when 



the animal is irritated, 

 it varies from a very 

 pale blue or lilac, to 

 a deep, crimson. Its 

 form is also very re- 

 markable, being a small 

 rather a parallelogram, 

 ends cut off, and lying tranversely 

 across the ball. {Jig. 50.) The 

 black tufts mentiohed above are the 

 lateral hoofs (fig. 51.), which the animal sheds annually, and 

 which grow to the length of five or six inches (a). They 

 are not shed together, or at 

 stated periods; for those of 

 the fore feet [a b), in this 

 example, are at present of 

 different ages, and, conse- 

 quently, of different lengths, the difference between them being 

 exactly that represented in the sketch. 



On the hump, or collar, the hair grows much longer than on 

 the other parts of the body, forming a sort of curled mane, 

 resembling, I should imagine, that of the bison. It is perfectly 

 white, growing to the length of 1 ft. 6 in., and adding greatly 

 to the height of the rising part behind the horns. At present 

 the hair is only beginning to grow, but it will be in full beauty 

 at the approach of the winter months, and will fall off gra- 

 dually again in the early part of the succeeding spring. 



The keeper 

 pointed out to 

 Mr. Harvey, as 

 a remarkable 

 peculiarity, that 

 the dewlap (fg. 

 52.), in passing 

 between the fore legs («), and under the body {b), seemed to 

 divide itself into three parts, which they called the three 

 stomachs (1, 2, 3), from their being very much acted on in the 

 progress of digestion. I remain, Sir, &c.
