leading us away from the chief danger. He shows that in 
lands like Egypt the indigenous inhabitants retain immunity 
while associating for long periods with consumptive immi¬ 
grants ; while on the other hand, in regions like Australia and 
the Sandwich Islands, the inhabitants have become infected 
after the introduction of dairy cattle. The best dairy cattle 
breeds, he argued, are the tubercular breeds, while some 
breeds not classified bv the breeder as dairy cattle are exempt 
from tuberculosis, owing to their vigor and health. In all 
dairy countries the prevalence of tubercular consumption is a 
settled fact, while the only countries at all in doubt are those 
where the dairy consists of other than our domestic cows. 
Referring to China he spoke, of the pure Chinese as a people 
who did not use milk, while the Tartars in that country were 
meat and milk consumers, and therefore the observations of 
medical men are very confusing, and they confess that they 
cannot understand why the disease prevails among the domi¬ 
nant Tartar class and not among the poorer Chinese, who, 
according to all pre-conceived notions, ought to be tubercular. 
In South America, where cattle are exceedingly numerous, 
but the use of milk almost unknown, or used only after being 
boiled, the natives still enjoy an immunity. The Doctor, then 
taking a geographical square of ten degrees, embracing Spain 
and Morocco, contrasted the two countries, as the climatic 
conditions must be pretty nearly equal, but Morocco, where 
there are no European dairy cows, is exempt from tuberculo¬ 
sis, while in Spain and Portugal, where dairying is carried on 
in the European style, tuberculosis prevails. The Doctor 
ended by saying, as a physician and as a cattle breeder, that 
there was no great necessity for a disturbing alarm, because 
the benefits conferred upon us by the bovine race far out¬ 
weighed the burden of disease. If there were no way of 
remedying the disease he would be decidedly in favor of let¬ 
ting affairs remain as they were. He expressed, however, a 
strong opinion that dairy and beef cattle could be bred in 
such a way as to eliminate tuberculosis, but that that could 
only be done by increasing the price of both beef and milk,
