Excerpt from Photo-Micrographs of Frustulia Saxonica, Navicula Rhomboides, Body Scales of the Mosquito and Gnat Note, speak generally, as Mr. Hickie does, of what Dippel and others fancied they saw, but specifically of the longitudinal striae of Dippel. My reason for this limitation was, I confess, that I did not at the time know that any authority but Dippel had described longitudinal striae on this diatom. SO far as Dippel was concerned, I had not merely his description and his statement of the number of lines he observed to the inch, but the excellent and truthful woodcut in his book on which to form an Opinion. This woodcut, moreover, enabled me both then and now to know that the specimens I studied belonged to the same species as that which Dippel described.
