"Scientific American Supplement, No. 385, May 19, 1883"

There is no doubt that the profession believe that
intermittents have a cause; but this belief has a vagueness which cannot
be represented by drawings or photograph. Since I have photographed the
Gemiasma, and studied their biology, I feel like holding on to your
dicta until upset by something more than words.
In relation to the belief that no Algae are parasitic, I would state on
Feb. 9, 1878, I examined the spleen of a decapitated speckled turtle
with Professor Reinsch. We found various sized red corpuscles in the
blood in various stages of formation; also filaments of a green Alga
traversing the spleen, which my associate, a specialist in Algology,
pronounced one of the Oscillatoriaceae. These were demonstrated in your
own observations made years ago. They show that Algae are parasitic in
the living spleen of healthy turtles.
This leads to the remark that all parasitic growths are not nocent. I
understand you take the same position. Prof. Reinsch has published a
work in Latin, "Contributiones ad Algologiam," Leipsic, 1874, in which
he gives a large number of drawings and descriptions of Algae, many of
them entophytic parasites on other animals or Algae.
