30 Hallier, 
thesis, because true knowledge patiently awaits demonstration and 
absolute facts; but every reader of Prof. Hallier’s letter and 
Dr. Stile’s report concerning this parasite will not fail to remark 
how persistent and enduring is its own vitality. It survives and 
flourishes for months after being taken from the gall bladder and 
the blood of the infected bullock; and there is reason to believe 
that it would live and grow in muddy streams on various kinds 
of algae. It is certainly an interesting and suggestive fact that, 
so far as the researches of Dr. Stiles and Prof. Hallier have 
extended (to date of this report), the type of fungus which they 
have found developed from these spores is one that finds its home 
in the carex, the lolium, and the wheat-like or tilletia grasses. 
Whatever results may be attained in the researches now in pro- 
gress, including the examination of grasses, the cultivation of the 
fungus upon them and in fluids, as well as the study of the deve- 
lopment of the fungus in its several stages, will be equally inter- 
esting to herd-farmers and to hygienists. The results, whatever 
they may be, shall be given to the public through the proper 
channels.

After the manuscript for this report had been delivered to 
the Board of Health and arranged for the printer, the following 
communication was received January 11. from Prof. Hallier: 
Jena, December 18. 1868. 
Dear Sir. — To-day I can give you the results of my culti- 
vations of the fungus which you sent to me. As I mentioned in 
my last letter to you, the fungus of which the micrococci and the 
cryptococcus-like cells take their origin, is a species of the genus 
coniothecium. This form of coniothecium is the true brand form 
(anäerophytische Morphe) of the fungus, growing only in the in- 
terior of the strata, or at least not under the influence of the 
open air. You get it best by cultivating the bile on a lemon de- 
prived of the exterior portion of the pericarpium. 
The germinating cells of the fungus form, on most parts of 
the lemon covering, the penicillium form, of which resembles very 
much the penicillium syphiliticum. On the dryer spots of the 
lemon you will see filthy masses of a dark greenish color. If 
you put these masses upon the object-glass, and put a drop of cau- 
stic potassa to it, you will very clearly see the coniothecium fruits
