In the last issue of this Journal we have another characteristic Podura reiteration by Dr. Pigott. As I imagine that the number of believers in his ideas of structure is as small as the subject, I have not been inclined to notice that already controverted, and the patience of microscopists must eventually become exhausted by such repetitions of the same theme. As he, however, appears to claim without foundation some remarkable discoveries, I venture upon a few reminders relating to this theory of beads and accompanying colours. He says that having had the "boldness" in 1869 to state that in the best glasses there is a certain residuary aberration, "this raised a storm of opposition hardly yet subsided." This assertion is not borne out by the facts, and is quite ridiculous. No such storm was raised, to subside at last into a tranquil acquiescence of any discovery whatever. It may be remembered that after several of these reappearances, I, as nearly the only opponent, noticed his essays, and questioned the inferences alone that were assumed, never doubting that object-glasses were improvable, as my papers and work in this direction testify.
