I had demonstrated by repeated experiments that inoculations of yellow fever blood into animals--dogs, rabbits, guinea pigs--gives a negative result. However, this negative result might be because these animals are not susceptible to the disease. In the civil hospital in Vera Cruz in 1887, Dr. Daniel Ruiz ran a single inoculation experiment on a man. But, this experiment was inconclusive because the patient from whom the blood was obtained was in the eigth day of the disease, and it was quite possible that the specific germ was destoyed at that point. These were the facts surrounding yellow fever when Dr. Reed and his associates commenced their investigations in Cuba during the summer of 1900. In a preliminary note read at the meeting of the American Public Health Association, October 22, 1900, the board gave a report of three cases of yellow fever which they believed to be direct results of mosquito inoculations

The speaker of this story is a scientist.

But, this experiment was inconclusive because the patient from whom the blood was obtained was in the eigth day of the disease, and it was quite possible that the specific germ was destoyed at that point. These were the facts surrounding yellow fever when Dr. Reed and his associates commenced their investigations in Cuba during the summer of 1900. In a preliminary note read at the meeting of the American Public Health Association, October 22, 1900, the board gave a report of three cases of yellow fever which they believed to be direct results of mosquito inoculations

Dr. Reed's experiments in Cuba did not yield any new data.

I had demonstrated by repeated experiments that inoculations of yellow fever blood into animals--dogs, rabbits, guinea pigs--gives a negative result. However, this negative result might be because these animals are not susceptible to the disease. In the civil hospital in Vera Cruz in 1887, Dr. Daniel Ruiz ran a single inoculation experiment on a man.

The single experiment on a man by Ruiz occurred seven years after the 80th year of the nineteenth century.

The experiments on animals and the experiment on humans were negative for the same reason: that all test candidates involved did not have the germ present in their blood streams.

In some places the wires came very near together, and in others the spaces between them were so wide, that Wallace thought that the squirrel, if by any chance he should ever get put into the cage, would be very likely to squeeze his way out. Then, besides, Phonny had not measured his wires in respect to length, but had cut them off of various lengths, taking care however not to have any of them too short. The result was that the ends of the wires projected to various distances above the board, presenting a ragged and unworkmanlike appearance.

The wires were near together in all places.
