SECRETARY'S REPORT. 85 



AVERAGE FATALITY. 



But one herd has been left to run through the disease before 

 slaughtering, and of course the results are not so satisfactory as 

 if they were based upon observations on many herds. But 

 such as we have we give. 



Mr. Chencry's lierd ran through the acute stage of the dis- 

 ease pretty much unmolested, and 27 animals died out of 67 ; 

 about forty per cent. 



There were probably diseased 51 out of 67 — a trifle more 

 than seventy-five per cent., or 3 out of 4 animals. 



The relative value of the animals in herds affected, that do 



not die. 



The tendency to entirely recover is less than was supposed 

 by the senior member of this Board. Whether the nine ani- 

 mals found free from disease, after slaughter, in Mr. Chenery's 

 herd, were sick and had entirely recovered, or had never had 

 the disease, it is impossible for us to say. But so far as we 

 could judge from what we saw, the tendency to a removal of 

 the diseased substance is very slight, and it is fair to presume 

 that if the parent's constitution is injured by this or any other 

 disease, a like constitution may be transmitted to the offspring. 

 Their value as breeders would, therefore, be much diminished, 

 but, — as the following statements show, — they may be used for 

 beef without danger, and the milk is harmless. 



According to Delafond, when animals affected with acute or 

 sub-acute pleuro-pneumonia are slaughtered in a proper man_ 

 ner, their flesh is found to be of a beautiful red color, firm 

 without effusion, either bloody or serous. It makes a good 

 broth and the boiled meat is savory and digestible. If roasted, 

 there is no more serosity or juice than from the meat of a 

 healthy animal. If salted, it takes the salt well and is well 

 preserved. J. B. Huzard states that in 1789, when the disease 

 was most fatal, the flesh of animals attacked by the disease 

 was eaten with impunity. Many other authors, among whom 

 are Bcnoist, Hanemann, Bojarus, Dieterichs, Hoffacker, 

 Wagensfcld and Krheycn admit tliat the meat is not essentially 

 injurious to man. Delafond himself ate the meat boiled and 

 r(^j^stcd, and on one occasion made a breakfast of liver takeA 

 from a cow killed the evening before, and was not at all afifected
