INTESTINAL WORMS.

INTUSUSCEPTION OF THE INTESTINES. 
This is another evil arising from a long-continued spas¬ 
modic action of the ileum, which sometimes causes an 
inverted pressure from the caecum towards the stomach, 
which overcomes the natural action, which forces this con¬ 
tracted portion of the intestine into a portion above it, 
which retains its natural calibre. The irritation thereby 
produced increases the upward action, and causes still 
more of the intestine to be forced inwards, until an obstruc¬ 
tion of an insurmountable character is produced. Continued 
and unmitigated pain is the only symptom which may 
lead to a suspicion that this incurable malady has taken 
place. * 
INTESTINAL WORMS. 
A variety of worms inhabit the intestines of horses, and 
when they become numerous often prove injurious to the 
constitution of the animal. Although a respectable writer 
says they are not of much consequence unless they are 
numerous, we would recommend that the sooner they are 
expelled the better, however small the number may be, tor 
this simple reason—that where there exists a single pair 
there will naturally be an increase of their species. It 
is perfectly true that by what means they at first effect a 
lodgement into the animal system is a mystery yef to 
be solved ; but it is equally true that naturalists have 
detected that these parasites are formed male and female, 
and as Nature frames nothing in vain, they must propagate 
in the ordinary manner of reproduction. 
Symptoms.* —Loss of appetite, griping pains, a rough coat, 
and tucked-up belly, are symptomatic of worms of the 
larger species, lumbricus teres . or long white round-worms
