a number of granular forms were seen, and lialf-au-liour 
afterwards nearly all the parasites were motionless. 
Apstein, in his paper referred to above, has paid some 
attention to the physiology of this form. He states on page 1 1 
of this paper : Handelt es sich in unserem Falle um parasit- 
ismus, Oder spielen die Flagellaten vielleicht eine wichtige 
physiologische Rolle ? Ich mochte das letzere glauben. Das 
regelmassige vorkommen wurde allein nicht dafur sprechen 
Die Wasseraufnahme aber hat vielleicht den Zweck, den 
Magensaft des Seehasen so zu verdiinnen, dass die Flagellaten 
im Magen leben konnen, andererseits sie verdaut werden 
wiirden Welchen Nutzen die Flagellaten aber fur die Seehasen 
haben, vermag ich nicht anzugeben.” 
Under these circumstances I thought it might be of some 
interest to compare the length of life of the flagellate after 
the death of its host on a piece of stomach placed in sea-water 
with that on the stomach-wall of the dead animal. The 
experiment was not very convincing, however, as the mucus 
on the inner surface of the stomach-wall seemed to be coagu- 
lated to a certain extent on placing it in sea-water; still, 
forty-eight hours after the death of the host a few active 
forms were still found in the piece of stomach placed in sea- 
water, and quite a large number were found on the stomach- 
wall of the host. In the intestine of the Cyclopterus no trace 
of the parasite could be found. In the gall-bladder a very 
small Trichoniastix was found, and the rectum was crowded 
with bacteria and a very large spirochaeta.
