VERTEBRATES. 



two little pointed horns sprout, which are even, and terminate at 

 the head by a kind of knob ; the following year this knob grows 

 from the head, pushed out by a cylinder of horn, which forms and 

 terminates also by another knob, and so on ; for as long as the 

 animal lives, the horns grow : these knobs become annular knots, 

 which are easily to be distinguished in the horns, and by which 

 also the age may be easily known, by reckoning three years for the 

 first knob next the point of the horn, and one year more for each 

 of the intervals between the other knobs. 



The young ox is called a calf, and is quite as useful in its 

 way as the full grown ox. The flesh is called veal, and by many 

 preferred to the flesh of the ox or cow, which is called beef: jelly 

 is made from its feet. The stomach is salted and dried, and is 

 called rennet. Cheese is made by soaking a piece of rennet in 

 Water, and pouring it into a vessel of milk. The milk soon forma 

 curd, which is placed in a press, and the watery substance, called 

 whey, squeezed from it. The curd is colored and salted, and is 

 then cheese. ■*
