suggest that the examinations are not always conscien- 

 tiously performed. 



Salting the flesh kills the parasite in course of time, but 

 the discovery of trichina in either fresh or salted pork 

 should insure seizure. 



There are parasites harboured by the herbivora which 

 though not communicable to man are so to other animals. 

 The bladder worms mainly found in the peritoneal cavity 

 of sheep, Cysticercus tenuicoUis, produce Taenia marginata 

 of the dog. The flesh is fit for food unless otherwise 

 indicated on account of emaciation, but the affected portions 

 should be destroyed. Echinococcus veterinorum may be 

 found in all herbivora as cysts in the lungs, liver, and 

 other organs ; it produces T. echinococcus in the dog. The 

 flesh is quite fit for food, though the affected organs should 

 be destroyed. Sheep contract Coenurus cerehralis from 

 T. coenurus of the dog. When the brain is affected the 

 part should be destroyed to avoid further infection of the 

 dog. Sometimes the cysts of the disease develop in the 

 muscular tissue, and the condition is then known as measles 

 in sheep. 



In fluke disease of either sheep or cattle the flesh of the 

 latter is as a rule fit for food ; mutton may also be passed 

 so long as it is not pale and watery. In all cases the 

 affected organs should be destroyed. 



Calves suffer from Ascaris vituli which sometimes gives to 

 the flesh a peculiar sour smell, nauseating to some people 

 though not harmful. The intestines should be destroyed. 

 This rule should also follow in all cases where the wall of 

 the intestine is affected by parasites, which renders them 

 unfit for sausage skin purposes. 



Statistics of Condemnation. 



In the Metropolitan Cattle Market the veterinary officer 

 reported for the year 1901 that 947 whole carcases, and 

 275 partial seizures for disease were effected during the 

 year, out of a total of 167,937 animals slaughtered ; the
