liis monograph on the Gonidia of Mosses.* The cells escaping 
from the chlorophyll mass are devoid of colour, and escape by 
bursting of the blastoderm, and have at once independent rotating 
movement on their own axis. 
On August 31st, 1866, some yeast, flour, sugar, and water, 
were placed in a bottle under a vessel containing ozonized air 
(made by phosphorus), and gave off 35*2 per cent, of carbonic 
acid ; while the same quantity of yeast, &c., was placed under a 
jar of common air, and gave off 17 '3 per cent, of carbonic acid. 
By means of an air-sieve, I have collected distilled water 
trickled over a glass plate into a trough, and found varying quan- 
tities of Monas lens besides other air-contents. 
Paramoecia subjected to the action of solution of potassic per- 
manganate instantly cease to move, and assume a rust-brown colour, 
while the purple of the original solution is destroyed (manganic 
oxide ?). 
Solutions of potassic permang. (one centimetre equal to * 01 of 
a grain of organic matter), when added to water from the air- 
sieve, show discolorization varying from '01 to *10 to the pint. 
Kain-water shows a greater discolorization than distilled water. 
Distilled water sprayed through the air of my room shows 
• 40 grain organic matter to the pint. 
The following are the results of an experiment, March 5, 1868 : — ■ 
One pound cow-dung from centre of a recent deposit (kept in 
stoppered bottle six weeks), mixed with 20 oz. distilled water, and 
disposed of as follows : — 
a. 2 oz. in clean bottle, with only a bubble of air, corked and sealed. 
h. 1 oz. in 2-oz. bottle, corked and sealed. 
c. 2 oz. in open glass beaker, with carbolic acid, placed in rather 
dark room, 
d. 2 oz. placed in a saucer, exposed to air in a rather dark passage. 
e. 2 oz. placed in a round evaporating dish outside the window of 
my room. 
/. 2 oz. in square dish outside the window. 
g. 9 oz. in tall glass jar outside the window. 
e, /, g. Exposed to air and light and rain, examination showed the 
following results : — 
a. March Bth. — No moving germs. 
April 2nd. — „ „ Bottle accidentally broken. 
h. March bth. — No moving germ. 
„ 20^^. — A few monads ; Mucedo on cork. 
„ 22nd. — Monads very numerous, movement saltatory ; no 
Mucedo granules. 
„ 26th. — Monads and Vibrions very abundant. 
April 2nd. — Monads and Vibrions, all transparent, no green 
colour.
