■vvould call attention to the fact that under temperate weather conditions, as, 

 lor instance, on the Pacific slope, the prevailing type of Glanders, while decid- 

 edly infectious, is much milder than that seen in- roast other parts' of the 

 country. 



Sudden changes of weather seem to favour the development of acute cases, 

 while under steady heat or cold the disease frequently remains dormant. For 

 -this reason serious outbreaks are with us more comipon in spring and fall than 

 in the steady weather of winter and summer, i - 



I am aware that my conclusions as to what consititutes a typical reaction 

 to Mallein differ somewhat from those arrived at by the Eighth Internationa] 

 Veterinary Congress held at Budapesit last year. I have, however, been 

 guided entirely ^by the results of our own work, and as these are most convinc- 

 ing, I am inclined to attribute the variation, which is, after all, more apparent 

 than real, to a possible difference in cdnditionig bietween Europe and Ameirica. ' 



I need hardly point out that, in order to secure satisfactory results, the 

 conditions surrounding the animals should be normal while the test is being 

 conducted. The adminiistration of water, and even of food, the regulation of 

 "body ^/I'eat and of ventilation, must all be carefully watchied, in view of their 

 relation to thernjal change. For the same reason no exercise what-";ver .sho^uld 

 be permitted while the test is being carried on. 



fin conclusion I would- say that the operations which we haye conducted, 

 and their results, 'have shown in the most convincing manner the, great value 

 of Mallein as a diagnostic agent when intelligently used by careful and 

 experienced veterinarians. The expressed views of our inspectors on this point 

 indicate that it can be absolutely relied upon in about" '98 per cent, of the 

 animals submitted to its action. 



I tak;e this opportunity of expressing my, sense' of obligation ■ to those 

 Inspectors whose comprehensive reports have rendered it possible for me, to 

 thus summarize the results of our work. / 



I would add that on the occasion of the last annual, meeting of the 

 American Veterinary Medical Association, which was held in New Haven, 

 Connecticut, in August of this year, I laid before that body the facts set forth 

 in this report, with the result that the following resolution was unanimously 

 passed by the Association : ' ' 



"Whereas, in the presentation of Canadian state control work' with 

 Glanders by Veterinary Director-General Dr. J. G. Rutherford, it is apparent 

 that the Canadian Government has undertaken control work with infectious 

 diseases of animals upon a .scale that is highly creditable and in a way com- 

 munsurate With the importance of the work, and 



"W'hereas, actual results sihown in this report plainly justify the heavy 

 expenditures incurred ; therefore be it ' 1 



"Resolved, That we commend those in /higher Canadian Government 

 authority for thus generously supporting this work, and commend the ge'neral
