SCIENCE AND INDUSTRY.

Although we have failed to find even larval ticks in the great majority of the 
patches of exudate examined by us—even after using the microscope, we believe 
that they are a direct result of larval tick attack on certain cattle, i.¢., cattle 
which possess some individual physiological peculiarity. Such animals are 
resistant, and apparently the small quantity of tick toxin—perhaps even the mere 
mechanical stimulus caused by the insertion of the rostrum—is able to so increase 
the local blood pressure that there is an exudation of lymph. We have already 
stated our opinion that the blood of resistant animals will be found to Possess 
certain differences in regard to its biochemical composition. 
It may be objected that this exudate makes its first appearance each season 
before the presence of ticks is noticed, but we must point out that Jarvee begin to 
infest cattle some little time before the 
observer. 
We, then, agree with Mr. Pound in regard to this claim that the condition ig 
the result of tick attack, but we disagree with him when h 
ordinary tick sore. We agree with Mr. Hull that it is not the 
caused by excessive tick worry.

The British people had ignored science, or at best held 
it at arm’s length. Our policy of “ muddling through” had 
covered almost every sphere of human activity. We prided 
ourselves on being a “practical people,” and regarded science 
as a mere plaything for theorists. In the scheme of our 
great industries science was, until quite recently, treated as 
an Ishmael. Even now she was viewed with suspicion, yet 
to hope for success in modern industry without the aid of 
science was like attempting to navigate the trackless ocean 
without a compass.
