time we hear him exclaim, "I do wish I could sometimes ascertain the 

 exact juste milieu of work which will suit, not my head or will, these can't 

 have too much; but my absurd stomach." (Life and Letters, Vol. I, p. 

 131). Herbert Spencer voices the same sentiment when he says, "I want 

 a keeper to be always taking care that I do not overstep the limits on one 

 side or the other * * *." 



We need not be surprised that Huxley and men of his type did not 

 understand the influence of air conditions, when we consider that the 

 best medical meu, active practitioners of medicine, did not understand 

 it. The two most eminent physicians contemporary with Huxley were 

 undoubtedly Dr. Andi-ew Clark and Dr. ■ Henry Thompson. These men 

 were constantly sending their patients away from London. Dr. Clark used 

 to say, "What you need is rest, pure air, cheerful companions, simple diet, 

 and no end of out-doors." They got results, patients improved, but they 

 did not press their inquiry and seek the reason why. One can of course 

 readily excuse them for the same reason upon which Huxley must be 

 excused — They began work before the days of cellular pathology and 

 bacteriology and did not take it up in their old days. Perhaps needless 

 to say a knowledge of pathology and etiology is one of the absolute essen- 

 tials in studying dust infection. 



Huxley had a rural ancestry and that means that there had not been 

 an active weeding out through urban influences. When he first came to 

 London as a young man he seems to have gotten along fairly well, but in 

 time there was a greater and greater susceptibility to unsanitary urban 

 conditions and he reacted to his environment. He lived in the West End 

 where air conditions are good, and lectured at Kensington, which, as 

 some of you know, is situated half way into the heart of the city. At 

 first he could lecture several hours a day without difficulty, but after 

 a time he complained that he could only bear one hour and that two hours 

 'does him up.' Still later he was not able to do even an hour's work 

 under bad air conditions, but when he removed from the city and went 

 to the South Shore, he was again able to do an almost unlimited amount 

 of work.
