Virulence in America. 17 



1879, by Professors Liantard and McEachran, whereas, 

 on the occasion of my first visit, February 10th, there 

 ■were only between 600 and 700, and up to the time they 

 were quarantined, some days later, a large number had 

 been culled out and slaughtered in anticipation of State 

 interference. Of those that remained 64 were found so 

 badly diseased that they were killed and sent to the offal 

 dock,- while from 100 to 150 showing slight symptoms, 

 were sold for beef. Here we have one-tenth of a large 

 herd severely attacked, and if we add those that were 

 picked out by the owners in anticipation of quarantine, 

 and the infected animals disposed of for beef, there is 

 considerably over a third of the whole that were under 

 the influence of the disease. 



(6) In the course of last year (1878), William Post, 

 Old Westbury, Queens Co., L. I., bought a cow out of a 

 passing herd that had been brought by Levy, a dealer, 

 from Brooklyn stables. She infected his whole herd and 

 his brother's to such an extent that they had to slaughter 

 both herds, and, after a time, begin anew with fresh stock. 

 From that time, as before, they have kept sound. 



(c) .Mrs. Murphy, Brooklyn, last year bought a cow 

 from McCabe, a New York dealer, which infected all of 

 her herd, so that she had to slaughter the whole, and has 

 given up the milk business. 



(d) In January, 1879, Mr. Judson, "Watertown, Conn, 

 {and Gramercy Park Hotel, New York), bought two cows 

 of Hecht, a New York dealer. They took iU soon after, 

 and infected his original herd of ten. All were placed hi 

 quarantine by the Connecticut authorities, but were 

 smuggled off by Hecht (who had purchased them at a 

 ridiculously low figure), and shipped to New York, where 

 they were slaughtered by order of the authorities. This 

 is a case of the introduction of disease into a hitherto 

 sound locality and State, and has therefore a special si^ 

 nifieance
