    AUTHOirS PREFACE Whex I determined to publish the three memoirs which follow, it was with the intention of directing the attention of physicians to the medical and bio- logical importance of light, and especially of the chemical rays. These papers have appeared at different times : the first in La Semaine Medicale of June 30, 1894, under the title ‘ Les rayons chimiques et la variole ’; the second, in Danish, in the IIospitcdMdende, of Copenhagen, No. 8, 1895 — ‘ Lyset som Incitamen ’ (‘ Light as a Stimulant ’); and the third in La Semaine Medicale of Decem- ber 21, 1897—‘ Traiteinent du lupus vulgaire par les rayons chimiques concentres.’ As, for various reasons, I have not been able to rewrite them, their form has not been changed, with the exception of some corrections and supplementary remarlcs. I beg the reader to be kind enough to excuse their present form. The last article especially is only a very condensed summary.
