VACCINE-THERAPY 153 



In fact, in days gone by, when one used to see more 

 cases of purpura than one does now, Lugal's solution was a 

 most useful preparation, and in the writer's hands gave 

 many good results. 



Equine Influenza. 



The word " influenza," as used in veterinary medicine, 

 has a very wide meaning, and as such, in many cases, is 

 undoubtedly a misnomer — so much so that the clinician 

 recognizes a variety of diseases which may come under the 

 same heading. This is unfortunate, inasmuch as it admits 

 of laxity, and serves no useful purpose, so far as descriptive 

 details go. 



Certain it is an endeavour should be made to curtail the 

 meaning of the word, and at the same time there should 

 be drawn up a list of cardinal symptoms and lesions specific 

 in themselves to the disease in question. In this way the 

 meaning of the word itself would be more confined, and the 

 information it conveyed more accurate. One cannot help 

 recognizing, however, there are certain difficulties which 

 will remain until we are in possession of a more accurate 

 knowledge regarding the nature of the causative bacteria. 

 Some authorities hold the disease proper is due to a microbe 

 of the ultra-visible group ; others, that it is caused by a 

 coccobacillus which is always present in the primary 

 infective stage, and which is followed later by a secondary 

 infection, the causative bacterium in this secondary infec- 

 tion in most cases being a streptococcus. 



Admitting, then, the bacteriology of influenza is in such 

 a nebulous condition, one would suggest that here at least 

 the immunizer has reached his limitations, and at first sight 

 this would appear to be so. On looking more closely into 

 the facts, however, what do we find in practice ? 



Every practitioner with experience of influenza outbreaks 

 will agree that the disease influenza itself is in nearly every 

 instance a benign one, and that fatal consequences from 

 the primary and direct effects of the disease are practically
