955 The work was, however, interrupted by my departurefrom that town, and, unfortunately, the number of cases studied was not extensive enough to justify us recording our results. But so far as our investigation went we observed that the infected guinea-pigs which had received the tubercle vaccine survived longerthan those which had not, and that the vaccine could be administered to a greater variety of clinical cases. of tuberculosis and in much larger doses. The superiority of this lipoid-free antigen over otherforms of tubercle antigens is also indicated in the work on the complement-fixation test for tuberculosis independently conducted by Seller and Ramsbottom.I has yet to be done to establish the Although much " value of any defatted " tubercle vaccine as a therapeutic remedy, I believe as I did that a tubercle antigen, when free from lipoids, is more readily emulsified and more favourable to interaction with its antibody, in vivo and in vitro. I am therefore the more glad to see Prof. Dreyer’s research on the subject, and await his further results with much

CENTENARY OF THE LANCET.
To the Editor of THE LANCET. SIR,-I should like to add a congratulatory message to the many you have received on the Centenary of THE LANCET. I am the proud possessor of the first volume of THE LANCET, which belonged to my great grandfather, and bears on the fly-leaf the bookplate, " Thomas Steele, Surgeon, Reigate, Surrey." At his death it passed with a number of other early volumes of THE LANCET to my grandfather, John Sisson Steele, M.R.C.S., L.S.A., of Reigate. I myself inherited these volumes from my father, Dr. Russell Steele, of Hemel Hempstead. Though, alas, several volumes have disappeared since moving from one house to another, I am still the lucky and proud interest.-I am, Sir, yours faithfully, C. Y. WANG, M.D., F.R.C.P.
