Dr. Klein and “Photography of Bacteria.”

Abstract

ALTHOUGH I feel indebted to Dr. Klein for his appreciation of my work as expressed in his review in NATURE of August 4 (p. 317), still I must ask him to allow me to correct a statement which detracts very much from the credit of photo-micrography. Dr. Klein says:—“In connexion with this it must certainly appear remarkable that in the numerous and important publications on Bacteria by Koch and his pupils since 1877 to the present time we do not find a single illustration represented by micro-photography. All their published illustrations are drawings.”
