“In times of stress and danger such as come about as the result of an epidemic, many tragic and cruel phases of human nature are brought out, as well as many brave and unselfish ones.”

“He was one of life’s great helpers, for he cleaned up foul places and made them sweet.”

“The case which I reported on September 26, 1901, was really the last which occurred in Havana. Of course we did not know it at the time, but this case marked the first conquest of yellow fever in an endemic center; the first application of the mosquito theory to practical sanitary work in any disease.”

“It is almost impossible for contemporaries to judge the true value of discoveries, or to give the proper position to the men of their own time who make these discoveries. The Surgeon-General of the Public Health Service expected the greatest results to flow from his commission of medical officers, but the conclusions of the Board turned out to be all wrong, while he did not notice the report from his own subordinate, Dr. H. R. Carter, which turned out to be pure gold and was one of the great steps in establishing the true method of the transmission of Yellow Fever.”

“In times of stress and danger such as come about as the result of an epidemic, many tragic and cruel phases of human nature are brought out, as well as many brave and unselfish ones.”

“But such is the nature of man that as soon as you begin to force him to do a thing, from that moment he begins to seek ways by which he can avoid doing the thing you are trying to force upon him. A man with malaria parasites in his blood is a danger to his companions. To kill all the parasites, he was then required to continue doses of quinine a week or ten days after his fever. When the convalescing men were given their daily dose of quinine they would manage to throw their tablets out of the dispensary window. The old turkey-gobbler pet of the hospital gobbled up all the tablets he could find. He became so dissipated he finally developed a species of blindness caused by too much quinine. I cannot vouch for this, but I was often twitted with this story as an illustration of how the men were treating prophylactic quinine.”

“Fortunately for the cause of science and of humanity, we had as Governor-General of Cuba at that time General Leonard Wood, of the United States Army. General Wood had been educated as a physician, and had a very proper idea of the great advantages which would accrue to the world if we could establish the fact that yellow fever was conveyed by the mosquito, and his medical training made him a very competent judge as to the steps necessary to establish such fact. General Wood during the whole course of the investigations took the greatest interest in the experiments, and assisted the Board in every way he could.”
