A little inflammation appeared on all their arms, but died away without producing a pustule ; yet all these servants caught the disease within a month afterwards from milking the infected cows, and some of them had it severely. (He mentions the same failure, Three or four servants at a farm were carefully inoculated with matter fresh from a cow, in a letter to Woodville in the end of January, 1799.) For whatever reason, Jenner does not appear to have inoculated from the cow-pox which these very servants acquired accidentally a month afterwards, although he was in want of lymph to send to his correspondents. On November 8th Pearson again writes to Jenner : If I can but get matter, I am much mistaken if I do not make you live for ever; and five days later (November 13th) he writes him more urgently than before to provide matter for distribution : I wish you could secure for me matter for inoculation, because, depend upon it, etc. . . .
