178 CONTAGIOUS DISEASES. 



shippers there, in order to satisfy themselves of the correctness 

 of the diagnosis of the veterinary advisers of the Privy Council, 

 and who now hold the same position on the Board of Agricul- 

 ture, requested Professors M'Call, Walley, and myself to visit 

 Liverpool and examine the cattle, and watch the post-mortem 

 results ; and here commenced the dispute, as, after having seen 

 a few diseased lungs, I maintained that the malady was not 

 pleuro-pneumonia, but a catarrhal or broncho-pneumonia, com- 

 bined in a few cases with pleurisy, but in others the pleurisy 

 was absent. Professors M'Call and Walley agreed with the 

 advisers of the Privy Council, and I found myself in a magnificent 

 minority. During the spring and summer of that year several 

 condemned lungs were sent to me from Liverpool, and after 

 further investigation I found no reason to change my opinion. 



The matter remained in abeyance so far as the profession was 

 concerned until April 1891. It is very true we now and then 

 heard that pleuro had been detected amongst American cattle 

 landed in this country, but we had no means of verifying or 

 contradicting these reports ; but some two years or so ago the 

 American Government sent inspectors to the various ports 

 where American cattle are landed, for the purpose of investiga- 

 ting and reporting upon the cattle slaughtered ; and, wonderful 

 to relate, we heard no more of American pleuro, except one 

 notable report from Dundee, until a lung of an ox was found at 

 Deptford in April 1891, and said by Professors Brown and 

 Duguid and Mr. Cope, and confirmed by Professors Walley and 

 MTadyean, to have plcuro-jmeuinonia contagiosa, and in further 

 support of tlie correctness of the diagnosis Mr. Chaplin, the 

 Minister of Agriculture, said it was pleuro, for he had seen the 

 lungs. But Dr. Wray, the American veterinary inspector at 

 Deptford, disputed this opinion, and on 18th April brought a 

 portion of the lungs to me. 



I, along with my son, examined this portion of lung, and we 

 both came to the conclusion that it was not pleuro-pneumonia. 

 I was again in the minority, and nothing more would have been 

 heard of the matter, at least so far as I am concenied, had not a 

 remarkable coincidence occurred in Paris during the winter of 

 last year, when it appears that MM. Eedon, Godbille, and Blier, 

 well-known veterinarians and sanitary inspectors at La Villete — 

 the Parisian cattle market — where thousands of American cattle
