Tue Microscope. 263 
AFTER receiving a specimen of trichinw pork from the presi- 
dent of the Pennsylvania State Board of Health, the Anti-Adultera- 
tion Journal submitted twenty-five samples of pork, obtained of 
dealers in Philadelphia, Camden, N. J., Germantown, Williams- 
port, Lock Haven, Pa., Pittsburg, Wilmington, Del., Baltimore, and 
New York, to the microscope, and found that six of the specimens 
contained the trichine spiralis. These samples were taken from the 
largest and healthiest appearing hams. ‘‘ We are convinced,” says 
this journal, “ That trichinosis is on the increase, and that increased 
watchfulness is necessary to avoid the contamination and death in- 
cident to eating diseased pork.”

Toe GarPE Worm oF Fow1s, Etc., by H. D. Walker, M. D. 
Dr. Walker seems by his researches to have proven beyond dispute 
that the parasite producing gapes in chickens needs some interme- 
diate host in which to pass a certain period of its existence before 
developing in the chick. This host he finds to be the common 
earthworm (UL. terrestris). This subject has long puzzled observers, 
but is now, we believe, fairly settled by Dr. Walker’s interesting 
and valuable investigation.
