five minutes; this is asserted on an experience of 

 fhirty years. 



Its operation is thus accounted for: the. grubs, 

 from some cause, having abandoned their usual 

 food, seize upon the stomach, and when the warm 

 blood thus thrown in reaches them, they immedi- 

 ately loope their hold to feed on it; so that instant 

 relief follows. The bleeding has a tendency to 

 allay any fever caused by the attack, and if a suf- 

 ficient quantity is given, it will act as a purgative 

 and carry them oft'. 



It is not an uncommon thinjj for grubs to attack 

 a horse soon after he is relieved from the colic. — 

 They are disturbed either by the disease or the 

 means used to cure. When once roused to action, 

 they never fail to seize on the most vital and .dan- 

 gerous part. It would therefore be well, in all ca- 

 ses of either colic or grubs, to give an active purge 

 after the horse is relieved from pain; as when 

 loose, they are easily carried oft* with the medicine, 

 but when attached to the stomach, nothing that 

 would leave life in the horse could force them to 

 quit their hold. This may be demonstrated by at- 

 tempting to detach them from the stomach of a 

 dead horse. The grub is surely produced from 

 the nit; is frequently seen on horses, which only 

 requires heat and moisture to hatch: thus, if 

 sHghtly moistened, and the breath blown on it with 

 the hand partly closed, it will in a few moments 

 produce a most active little worm; which, if he 

 gets in the mouth, is as well calculated to travel 

 down the throat, as he is afterwards to produce 

 the most fatal effects. 



A few weeks feeding on green oats, or com cut 

 up, stalk, ear and all, will generally carry oft' most
