226 On Tunis Sheep, 



nature uniformly interdicts. To the ram, it is furnished, 

 that it may descend to the progeny. Perhaps also to 

 prevent the introduction of worms, or progeny of in- 

 sects, which may, in a pecuUar degree and manner, in- 

 fest sheep in warm climates ; in which the sheep of 

 every variety, are generally broad-tailed. 



The intestines, and all other parts, of these sheep are 

 remarkably clear of the kind, or any other species, of 

 worm ; or the knobs, found in the entrails, and other 

 parts, of sheep of other breeds. See Mr. Capjiers ac-

I have seen ingenious and speculative opinions, con- 

 cerning, what may as well be called an *' excres- 

 cence and deformity," — the protuberance on the back 

 of the camel; — another African animal. This bunch is 

 greater or less, accordingly as the animal is generally 

 fat or lean. The broad- tail of the sheep encreases or 

 diminishes in size, in proportion to the general state of 

 the fat in the carcase. But neither the bunch, nor the 

 broad-tail, is the " repository of all the fat." I never 

 knew it alledged that the bunch was produced by na- 

 ture in a sportive fit ; or owed its origin to "the art of 

 man." For its being placed where it is, I do not pretend 

 to account. Human reason only exposes its own defici- 

 encies, when it attempts to account for unaccountable 

 things. This appears in more important subjects, than 

 those of the broad -tails of sheep, or the bunches of 

 camels. 



I should not have deemed it necessary to annex the 

 following certificates, which might have been muhi.
