ON WORMS IN GENERAL. 



What inveterate obstacles these insects are 

 to a Horse's improvement, where they have 

 unluckily gained possession, time and experi- 

 ence have sufficiently demonstrated ; though 

 an eminent writer on tlie subject says they do 

 good ; but this I cannot see ; for a toad, or a 

 snake, may be said on the same grounds to do 

 good, as no living animal taken into the sto- 

 mach becomes destroyed by the gastric juice. 

 However, I consider them of as pernicious 

 a nature and destructive a tendency, that 

 having at once secured a i>*ttlement in either 

 the stomach or intestines, the Horse becomes 

 a prey to perpetual depredation, till effec- 

 tual methods are taken for their total ex- 

 tirpation. 



There are three kinds of worms to which 

 tlie Horse is liable to ; first, the long white 

 worm, very much resembling the common 

 large eartii worm, but much longer and 

 harder; at its middle it is about the size of a 

 large swan's quill, and regularly tapering off 

 to the ends. The length of these worms are 

 various, from six inches to twelve; they 

 generally occupy the small intestines, and are 

 at times exceedingly troublesome, frequently 

 occasioning gripes, and not infrequently in- 



flammation of the intestines, by their exce8.«ive 

 irritation. 



Another kind of worm is the small thread 

 or needle worm, and is frequently found in all 

 parts of the intestines, but more particularly 

 in the large intestines. They have also been 

 found in some of the blood-vessels, in the 

 windpipe, in the lungs, &c. These worms 

 occasion great disturbance in the system 

 when they become numerous, but not so much 

 as the last named. 



There is a third kind of worm, called botts ; 

 these are of two kinds (which we will endea- 

 vour to explain presently), that one is larger 

 than the other, the large size generally taking 

 the cuticular coat of their stomach for their 

 abode. These worms are exceedingly offen- 

 sive, not only impairing and debilitating the 

 stomach, but very frequently produce inflam- 

 mation of that important organ. This worm, 

 or grub, has a peculiar form at its tail of two 

 processes, in the form of pincers, which when 

 he has the good fortune to make fast in the 

 coat of the stomach, his attachment is .--o firm, 

 that even in the dead subject considerable force 

 is required to remove them. This attachment, 

 as I said before, is at the tail, its head lying 

 pendulous in the stomach, indulging in any 

 thing the Horse may have to take down ; and
