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 peculiar 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. Capner’s ac-

I have seen ingenious and speculative opinions, con-

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

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 mulkti-
