Vlll PRESIDEXTI.\I. ADDRESS. 



the bother, I'll be blowed if the beedle bint bi<fger nor that, 

 and all of yon knoAvs Apsley House is a million times big^'er nor 

 the beedle.' The audience seemed perfectly satisfied with the 

 demonstration ; for mankind are always much obliifed to anybody 

 "vvho will be at the trouble of liumbujj;<fing them in their own 

 Avay, and fortunately there will never be a lack of persons to do 

 them this kindly office, puttint^^ profit of course entirely out of 

 the question. 



From these remarks I do not wish to infer that every stock- 

 owner I meet is ignorant of the nature and iises of the microscope ; 

 far from it. I have met with some who, I am pleased to say, 

 are able to give a number of extremely useful tips and dodges in 

 general microscopy, and in fact are (piite familiar with some of 

 the recent discoveries in practical bacteriology ; on the other hand, 

 there are hundreds who, if they had the aptitude, are unaljle to 

 meet with the opportunity of acquiring even a rudimentary 

 knowledge of the microscope or its revelations in connection with 

 animal diseases. 



I intended when I commenced Avriting this address to 

 briefly describe all animal diseases the study of Avhich is known 

 to ])e associated with the microscoj^e ; Vnit I find that by dealing 

 with the more important details of only four or five of the more 

 connnon or every-day diseases, 1 shall be doing all justice to my 

 subject. First of all I will take Anthrax, as it was the first 

 connniinicabl(» disease discovered that was proved (by means of 

 the microscope) to be caused by a specific organism, and it would 

 be no exagger:iti(m to say that the study of Anthrax has been the 

 ground-work for much of our recent bacteriological knowledge. 



ANTHRAX. 

 Anthrax, sometimes called Splenic Fever or Cumberland 

 Disease, is a disease which is largely seen in ca,ttle and sheep, and 

 sometimes in the pig, horse, dog, and other domesticate^! animals; 

 in fact, very few animals are proof against inoculation contagion. 

 It is the most deiuUy disease to which the animal body is heir, 

 and it runs its course with greater rapidity than does any otiier 

 jlisease with which we are acquainted, death" frequently resulting 

 in cattle and sheep within the space of one (1) or two (2) hours 

 iiher animals have been observed to be to all outAvard appeai'ance
