Lastly, the shape of the teeth, which is in general pyramidal,the base being at the extremity and the apex in the socket,ceases to be so much so in old age, and approaches more to acylindrical form.* Merinos keep their teeth longer than other breeds, althoughthey change them sooner. The habit of living in the midst offlocks, of observing them, of handling them often, teaches othermeans of discovering their ages, after the teeth no longer affbrdany certain criterion. When the eyes are less lively, the lipshanging down, the nostrils wrinkled, it may be presumedthat an animal is not young. It will readily be believed that * The knowledge of these details is the fruit of a conversation Girard, professor of anatomy in the veterinary school of Alfort, andof an examination which we made together of a great number of under-jaws of [93] these signs alone can afford no more than probable conjectures ;but it is not always an object of importance to determine theage precisely. It has been supposed that the age of rams isindicated by the rings on their horns ; but these rings are notsufiiciently i egular to afford a certain rule. It should be observ-ed that, when the pasture is coarse, sheep lose their teeth muchsooner. Tliis circumstance should be attended to. Sometimesalso the teeth of particular sheep wear out very soon.
