    there was absolute proof that theUymph had reallj' been absorbed by the lymphatics, that we should have expected syphilis to follow. But no! not until the lymph has been taken from a vaccinifer in whom the vesicles were shallow, and therefore difficult to prick without drawing blood, was syphiHs conveyed. E. An ordinary lancet was used. Nothing is stated as to whether this lancet was new, or whether it might not have been imperfectly cleansed after some previous vaccination or other operation on a syphilitic subject. The first vesicle which Dr. Cory opened bled, and he therefore abandoned it, and after wijping the lancet clean opened another. (a) The first vesicle bled easily—it, like the other vesicles, was shallow, and con- versely they equally with it were prone to bleed at the sUghtest touch. (hj Wiping the lancet clean is not sufficient. To have ensured the a&sewce of blood, as the first attempt had drawn blood, a new instrument should have been used. Students of mycology will know that no amount of wiping, unless accom- l^anied by the most careful use of ger- micides, will suffice to render a surface, once contaminated, absolutely free from taint. F. We are not told what was done with the remaining lymi^h wliich Dr. Cory preserved in a tube, but was only sufficient in quantity to partially charge it. Had this remaining lymph been carefully examined under the microscope for blood, and found free, there would have been some presumptive evidence that the portion used was also free. G. Arguments A, B, C, D, and E apply with equal force to the cases of Professor Gaspard Cerioli (page 77) and M.MiUard(page8o). n //) E. From the proposition that it is conclusively proved .... blood, I must beg to dissent. There is indeed no evidence that the lymph used did not con- tarn blood, and we are forced to the conclusion, in the absence of such evidence, that, instead of being
