    We do not know how far Jenner's lymph was successively carried on by the recipients abi'oad. Stromeyer {op. cit.), gave up the use of the lymph sent to him by Jenner, pre- ferring that sent by Pearson ; but at Berlin the use of Jenner's lymph seems to have been continued. The lymph sent to Waterhouse by Haygarth, though apparently suc- cessful at firstj became useless later on; according to Water- house this was due to careless and ignorant management. Of the later supply sent by Jenner himself no such com- plaint is recorded, and this probably, together with that sent to Waterhouse from Ring, which also was Jenner lymph,^' continued to be used in Massachusetts; though it is impossible to separate the use of this lymph from that of the lymph received by Waterhouse from Woodville and Pearson (which was probably Hospital lymph ■'■') and from Lettsoiu [Baron, I., 471). Unless we are prepared to assume (i) that all the lymph distributed abroad by Pearson and Woodville was derived from Woodville's original cases, and none of it from the other sources used by Pearson and even by Woodville himself ; (2) that all the Jenner's lymph sent abroad hj Jenner hmself or by others was derived from the Hospital lymph sent to Jenner by Woodville, and none of it from the Clark's farm lymph, which Jenner used and distributed so largely ; or (3) that all the Clark's farms strain sent abroad, failed or was discontinued, the lymph of Hospital source alone maintaining its position ; we must conclude that the Ij-mph by means of which vaccination was established abroad was not exclusively that derived from Woodville's original cases. Por such assumptions there is no positive evidejice at all, and probabilities at least are entirely against thbm. Further, all the lymph employed abroad in the early dayp of vaccination did not come from England. Sacco, for instaiice, discovered natural cow-pox in Lombardy, and both he land De Carro, of Vienna, made large use, with positive results, of the lymph obtained from this source; its efPects were identical with those of the lymph obtained from Engla'ud, i. e. from Woodville or Jenner. This Lombardy cow-pox is stated by De Carro to have been the origin of the lymph which he sent to Constantinople, and which started vaccination in
