products that we should desire to safeguard our own existence 
in every possible manner. In no line of endeavor is the acciden¬ 
tal hazard so great. This feature should be considered in the 
construction and equipment of buildings for the purpose. 
' You are aware that a biological product prepared by a certain 
manufacturer always gives uniform results and is seldom or 
never followed by after effects of a serious or annoying nature. 
When this particular product is for any reason unavailable, and 
a substitute is used in its stead, less favorable results follow and 
serious after effects may occur. The repeated occurrence of 
similar difficulties may be anticipated until it becomes the busi¬ 
ness of some properly constituted authority to examine all such 
products manufactured or offered for sale in Canada. The 
manufacture of the products now used in Canada provide a 
source of revenue to individuals and companies, and, therefore, 
the potency is to a very large degree'dependent upon the integ¬ 
rity of these individuals or companies. On the whole the in¬ 
tegrity displayed has been of a very commendable order, al¬ 
though we are aware that the trade relations of this country 
were seriously jeopardized a few years ago by an outbreak of 
foot-and-mouth disease in the country to 1 the south of us which 
was finally attributed to the use of a contaminated virus in the 
preparation of small-pox vaccine. 
At the present time, the biological products available for use 
'in Canada, with a very few exceptions, are imported, and there 
are at present no restrictions exercised over the facilities pro¬ 
vided for use in connection with their manufacture, nor is any 
standard established to which they must conform before being 
offered for sale. As a laboratory worker with an intimate 
knowledge and an extended experience in the manufacture of 
certain biological preparations I am convinced that there should 
be some restrictions placed, not only on their sale, but on the 
safety of the surroundings and the conditions maintained during 
their manufacture. 
Will meet you at Indianapolis, August 26-27-28-29-30.
