lias found that these three Mucedineae possess a very energetic sacchari- 
fying power : that of A. Oryzse being the most intense, Amylomyces next, 
and Mncor alternans last. In all the media examined, Amylomyces left 
more hydrates of carbon untransformed than the other two, owing to 
its combustive power being much less. Amylomyces possesses a more 
•considerable fermentative power than the other two, owing to its feebler 
combustive properties ; and it is the only one useful in practice for indus- 
trial purposes, either for direct fermentation of amylaceous substances or 
for the utilisation of distillery residue. The three Mucedineae were cul- 
tivated at 30° C., and in the following media : — (1) sterilised sucrase-free 
yeast-water, to which were added starch, dextrin, saccharose ; (2) brewery 
wort; (3) distillery wort; (4) distillery “ vinasse,” i.e. the residue after 
alcoholic fermentation. 
Pathogenic Action of Blastomycetes.* — Prof. F. Sanfelice, in a 
further communication, supports his contention that the bodies found in 
certain neoplasms, and described by numerous authors as Sporozoa, are 
nothing else than Blastomycetes. The results of inoculation with cul- 
tures of Sciccliaromyces neof ormans on Mus musculus, white rats, rabbits, 
•dogs, and fowls, were confirmatory of the author’s view. Tumours were 
developed not only at the primary injection site, but were found also as 
secondary deposits. S. neof or mans was found in the primary and 
secondary deposits ; the Blastomycetes were usually free and not intra- 
cellular. In one dog the tumours were epitheliomatous. 
Pathogenesis of the Soor Fungus.f — Dr. M. Steiner has shown by 
experiments on rabbits, that the Soor fungus may be pathogenic to 
animals. By injecting suspensions of pure cultures of the Soor fungus in 
•0* 6 per cent, salt solution, into the ear or jugular vein, a general my- 
cosis was induced, but not in all cases. The dose injected was 1 ccm. 
per kilogram of animal. The fungus was found in pure cultivation in 
every organ and part of the body where the injection was successful. 
The foci where the fungus was deposited were surrounded by a small- 
celled infiltration. 
Mycorhiza of Corallorhiza.J — Mr. A. Y. Jennings describes the 
mycorhiza which infests the parenchymatous tissue of the rhizome of 
{Jorallorliiza innala, and spreads out for a long distance into the surround- 
ing soil. The hyphae of the mycorhiza penetrate the epidermal cells of 
the host through long tufts of hairs, which serve for their collection and 
transmission. The mycorhiza appears to belong to an agaric, probably a 
Tricholoma or Clitocybe.
