In public esteem, the Rockefeller Institute undoubtedly occupies an exceptionally hight position. It would seem to be generally believed, that by reason of experiments made within its walls upon the lower animals, discoveries of the utmost value to the human race are bing added to the resources of medical science. Possibly, a careful analysis of its work might disprove this belief, but that is aside from present inquiry. A more important question confronts us,--the extent to which under the authority of this Institution, human beings as well as animals have been used as "material" from researches altogether unconnected with their personal benefit. If such experiments have in truth been made under the authority of the Rockefeller Institute, it would seem to be of the utmost importance that the exact truth be made known. It is not always easy to state medical facts in popular language, but the attempt shall be made. --------------- When Columbus returned from his discovery of a new world, it is now generally believed that he brought to Europe the germ of one of the most terrible diseases which have ever afflicted the human race.

In its contribution to the sum total of suffering which disease has occasioned the human race, it is probably that with one exception, syphilis stnds above every other human ailment.
