326 THE DISEASES AND DISORDEES OP THE OX. 



from diphtheria was for a short time employed to groom a mare, 

 which animal in a few days was aflfected with *' strangles," shown 

 by much swelling at the angle of the jaws, and a very foul 

 discharge from the nose. At Yateley, diphtheria in the human 

 subject was in two instances coincident with strangles among 

 the horses. 



Dr. Ogle relates that he met with a case in which diphtheria 

 broke out in a shepherd's family shortly after a throat disease 

 had prevailed among the sheep. 



There seems at least to be sufficient evidence to encourage 

 careful inquiry as to connection betwixt diphtheria in man and 

 certain affections in animals. It is said that in the Australian 

 bush diphtheria sometimes appears under circumstances which 

 almost preclude any conveyance of infection by human beings 

 or by prevailing winds. [We may here add that the same has 

 been said of the occurrence of typhoid fever in isolated localities 

 in South Africa and elsewhere.] 



We proceed to speak now of diphtheria in the ox. In doing 

 80, we cannot but feel regret that what appears to be known at 

 present regarding this matter is very incomplete, and short of 

 imparting satisfaction. Once again we may reiterate that these 

 questions as to the connections between allied diseases in dif- 

 ferent classes of animals deserve the most careful and the most 

 thorough and painstaking investigation, as indeed they are now 

 receiving at the hands of able scientists. Years and years of 

 prolonged research will be necessary before we shall be able to 

 say that we are really beginning to comprehend the workings of 

 disease, and no one should lose an opportunity of arousing some 

 of that enthusiasm among workers in the field of science, which 

 must be acquired in order t(; carry them through the immense 

 amount of labour which is necessary in order to solve these 

 weighty and most momentous problems. 



It was, we believe, in the year 1880, that Mr. W. Beach, 

 to whom great credit is therefore due, brought forward the 

 belief that the disease known by the name of diphtheria as affect- 

 ing human beings, also invades cattle. He suggested, and seemed 

 to believe, that the disease which he considered to be diphtheria 

 in oxen originated from the disease of the human subject known 

 by that name. The symptoms seem to be somewhat as follows: 

 — ^The pulse is quick, the throat is sore and swollen, and
