THe Botton MicroscopicaL SocieTy.—Since the Summer 
recess the Society has had two meetings, on each of which interest- 
ing papers have been given. At the September meeting Mr. W. 
Tyson gave a very interesting account of various forms of starch 
and the method of preparation, after which he gave various samples 
to the members present, in order that they might examine them at 
leisure. At the meeting held in October, Mr. Parr, Hon. Sec. of 
the Bury Natural History Society, gave a well-illustrated paper on 
the Mouths of Insects. After the Lecture various slides illustrative 
of the paper were examined. 
LivERPOOL MicroscopicaL Socirty.—The seventh ordinary 
meeting of this Society was held on Friday, October 3, when Mr. 
Frank T. Paul, F.R.C.S., read a paper on “Some Experiments 
with Microphotography,” illustrated by the oxyhydrogen lantern. 
After the paper, the following objects. were exhibited :— 
Crystals of Sugar (Cane) Polarised; Eyes of various Insects, 
living; Fern fructification in situ, varieties; Fibro cells of Oncidium ; 
Fruit of Bidenscernua; Lunar Photograph, “Copernicus”; Pistil 
of Arbutilon; Section of Eye of Drone Fly; Seeds, various ; 
Specimens illustrative of the Paper; Spiracle of Dytiscus ; Spores 
of Equisetum ; Tran. Section Pteris Aquilina, Polarized. 
Dr. KocH AND THE CHOLERA BAcILLus.—It is reported from 
Berlin that Dr. Koch has succeeded in communicating cholera to 
a number of rabbits by inoculating them with pure cultures of the 
“comma” bacillus. The rabbits at any rate sickened and died 
with symptoms resembling those of cholera. The intestines were 
found to be infested with the “comma” bacilli Should this 
announcement be confirmed it will go a long way towards establish- 
ing Koch’s opinion that the microbes in question constitute the 
true virus of cholera. Nicati and Ritsch are said to have anticipated 
this experiment in Marseilles about three weeks ago, and to have 
obtained the same results. ae 
THE CHESTER SociETY OF NATURAL ScIENCE.—A very nice 
little handbook has been issued under the auspices of this Society. 
It is entitled “‘ A Short Handbook of Natural History,” for use at 
Annual Conversazione and other meetings of the Society. It is 
published at the modest price of sixpence, and may be obtained 
from Mr. G. R. Griffith, Grosvenor-street, Chester.
