"We write these words not because we believe that any physician is so far fallen below the lowest levels of our common humanity as to inject into a defenceless child the active germs of a loathsome or possibly fatal disease, but because our moral sense is outraged at any treatment of the child such as we should refuse to permit were the child our own. We believe he universal assertial of parents would be that, if having taken their child to a hospital for tratment, they learned that it had beenused for experimentation, though no lasting harm could come to it from the experiment, someone would pay the penalty for the unwarranted deed, if money or influence or, these failing, muscle, could reach far enough to find the offender." Does such condemnation of experimentation upon the hospital patient or children tend to block scientific advance? Not at all. A recent writer tells us that "once it is evident that man himself must be the experimental animal, the scientist volunteer is always ready." If this be so, why should not the human "material" be acquired always in a way to which the charge of unjust procedure would never be applicable? If assurance could have been given that the luetin test implied no risk of any kind, might not the Rockefeller Institute have secured any number of volunteers by the offer of a gratuity of twenty or thirty dollars as a compensation for any discomfort that might be endured? Of the thousands of medical students in the State of New York, are there not hundreds who would have offered with eagerness to submit to a test devoid of peril, in the interests of scientific research? And even if an experiment implied danger, might there not be sufficient compensation for all risks? Every year firemen lose their lives in the flames, and policemen are murdered. The compensation they receive induces them to incur risks that might not otherwise be assumed. A great theologian is said to have affirmed that a man, perishing from starvation, had the moral right to take a loaf of bread that did not belong to him, if only thus he could preserve his life. Is Science ever in such straits of necessity that in a single instance it is obliged to take from any man his supreme right of inviolability, and to make its experiments within the wards of the hospital, upon the eyes of the dying, upon the bodies of the ignorant and the poor?
