four or five hundred joints of thefe worms, whofe 

 united length would encircle the whole body many 

 times. I have feen inftances where one of thefe 

 worms coiled itfelf up into one ball, and fo made an 

 impenetrable obftrudion, of which the dog died. 

 Another kind is the long round XLonn, fimilar to the 

 human. Thefe fometimes crawl from the inteflines 

 into the ftomach, and, making the dog Tick, are 

 brought up ; at others, they pafs only from the anus; 

 but I have obferved they more frequently produce 

 fatal elfeds when brought by the mouth. There 

 is a third kind, not much unlike maggots, with red 

 heads : thefe are not fo frequent as the two former, 

 and I think not fo fatal. A fourth kind, which are 

 likewife lefs fatal, are fimilar to the human afcarides, 

 or thread worm. 



Worms are particularly fatal to puppies; and 

 when they exift in any confiderable quantities, they 

 commonly deftroy them. Worms are eafily detected, 

 even though they fliould not pafs away ; for, when a 

 dog has many worms, hi? coat always ftares ; he 

 cats voracioufly, but feldom fattens ; he has fre- 

 quently a cough, and in puppies the nofe commonly 

 runs : but the ftools arc the moft unequivocal fymp- 

 toms ; for thefe are commonly loofe, flimy, and 

 mixed with froth. Sometimes, when loofe ftools are 

 the confequence of worms, on the taking any aflrin- 

 gent medicine, they become of a proper coniiftence,
