280 PROCEEDINGS OF SUCIETIES. 
tissues ; that fungi lie dormant a long time in the system, until 
favourable conditions occur to promote their growth; that fungi 
only become sources of inducers of disease when they develope to 
an undue amount; that fungi will not flourish on a healthy 
surface; the distinctive features of vegetable and animal structures, 
especially artificial germination; and the effects, chemical and 
other, produced by the growth of fungi. Dr. Fox illustrated all 
these different conditions by a reference to the phenomena of 
“ringworm” and allied diseases. Mr. M. C. Cooke gave anumber 
of very interesting facts in reference to the parasitism of plants, 
entirely confirmatory of Dr. Fox’s observations, detailing cases in 
which the germs of mildew and rust must have entered very early 
indeed into plants, and even been contained in the seed, develop- 
ing as the “‘plant grew up;” also where the elements of rust 
entered through the first pair of young (cotyledonous) leaves. 
He also stated that he never looked for parasitic fungi on those 
plants that appeared vigorous and healthy, but was sure to find 
them on those which looked sickly or grew in unhealthy places. 
After a few complimentary remarks from the President and others, 
a second and short paper was read “On a New Mode of Mounting,” 
by Mr. N. Burgess, who exhibited a number of beautifully pre- 
pared specimens in illustration of the process which he recom- 
mended. Mr. Burgess uses slides of a much larger size than usual, 
so that the whole area of a large object can be displayed in the 
same specimen, and his method is one well worthy of adoption 
by amateurs. The meeting terminated with the usual microscopic 
conversazione.
