Dr. Reed got from Dr. Finlay the eggs from which he raised the mosquitoes used in his experimental work. Dr. Finlay says on page 1 of his “Agreement between the History of Yellow Fever and Its Transmission by the Culex Mosquito”: “The experiments made by Drs. Reed, Carroll, Agramonte and Lazear were started in June, 1900, with a brood hatched from eggs of the identical insect which at Dr. Lazear’s request I had handed to him. All the successful experiments have hitherto been made with that particular mosquito.” Dr. Reed says in his paper, “The Etiology of Yellow Fever, Preliminary Note”: “We here desire to express our sincere thanks to Dr. Finlay who accorded us a most courteous interview and has gladly placed at our disposal his several publications relating to yellow fever, during the past nineteen years; and also for ova of the species of mosquito with which he had made his several inoculations. An important observation to be here recorded is that according to Finlay’s statement, thirty days prior to our visit, these ova had been deposited by a female just at the edge of the water in a small basin, whose contents had been allowed to slightly evaporate; so that these ova were at the time of our visit, entirely above contact with the water. Notwithstanding this long interval after deposition, they were promptly converted into the larval stage, after a short period, by raising the level of the water in the basin. With the mosquitoes thus obtained we had been able to conduct our experiments. Specimens of this mosquito forwarded to Mr. L. O. Howard, Entomologist, Department of Agriculture, Washington, D. C., were kindly identified as culex fasciatus—Fabr.” CHAPTER II THE EXPERIMENTS OF THE REED BOARD After consultation, the Reed Board determined to experiment to see whether the mosquito really did convey yellow fever. But it was necessary to have a good deal of money and sufficient authority before starting in. The Board had come to Cuba for entirely different investigations, and had not been supplied with sufficient funds for these experiments. 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. Dr. Reed outlined to General Wood the course he expected to pursue, and General Wood was so convinced by Dr. Reed’s argument that he authorized the expenditure from Cuban funds of a sufficient sum and gave Dr. Reed ample powers as to the method of expenditure.
