    APPENDIX S noted in the Preface, I here append references /Ato three recent publications from the Finsen Institute which seem especially useful and indicative to students in other countries. Dr. Carl Sonne : Acta Eadiologica, Vol. II., Fasc. 2, 1923. “ A Thermo-needle, with inset regulative heating apparatus, together with some measure¬ ments of cutaneous, subcutaneous and intramuscular heat endurance.” The author shows that a temperature can be endured several degrees higher beneath the skin than on its surface, without any sensation of pain being felt. This corresponds to the fact that, when irradiating the surface of the skin with luminous or dark rays, a far greater volume of energy is absorbed from luminous rays, which for the most part are absorbed deeper down, than from dark rays, where the energy is absorbed on the surface. Dr. Carl Sonne : Acta Medica Scandinavica, Vol. LVI., Fasc. VI. “ Investigations on guinea-pigs relating to the influence of the light bath on the action of diphtheria toxin in the organism.” The author shows that the general light bath, by its specific warming of the blood, tends to the rapid destruction of the diphtheria toxin. The destruction in the course of a single light bath lasting two hours, without the production of any fever (rise of the general body temperature) is as great as that caused by a general fever of 40° C. lasting several days and nights. The possible significance of this remarkable result for the treatment of such diseases as diphtheria will be evident to the reader.
