The statement has recently been made that nothing further is to be learned from the clinical side of study in dermatology, and that all progress in this direction must come from effort to exhaust the possibilities of bacteriology and histology.
Granting that the preponderance of recent advances have been due to the finer scientific explorations with the aid of instruments of precision, and that this must continue to be the case, still, I can not believe that the clinical field has been exhausted. If it were not as true as it would seem to be that there is nothing new beneath the sun, the proposition that clinical discoveries are at an end might be successfully defended.
