cumstances, 
_ FiaceLiaTe Inrusoria.—Dr. E, Cutler describes a flagellate 
infusorium called Asthmatos ciliaris, which occurs in connection 
with one form of contagious cold coryza or influenza. These par- 
asites may be easily detected in the early sneezing stage, when the 
nose and the eyes run water ; they are located in the anterior nasal 
passages, on the mucous membrane of the conjunctiva of the eyes, 
and of the pharynx and larynx. Simply transfer a drop of the thin 
mucus to a slide, cover, then examine with a good 1-5th objective 
and x inch ocular.—Swence. 
_ Ravuin’s FLurp.—For the culture of micro-fungi this is the best 
liquid extant. Pasteur in his experiments used the ashes of yeast, 
but his chief assistant, M. Raulin, prefers the following :—

For those unacquainted with the French system of weights and 
measures it may be useful to add that grains may be weighed off 
instead of grammes. 
THE LATE M. Nosert.—Microscopists of the future have M. 
Nobert’s legacy, to resolve the lines on his last test plate. His 19 
band plate, ruled on a 3 x1 slip, contains lines numbering from 
II,000 to 112,000 to the inch, and may be obtained from Mr. 
Wheeler, of Tollington Road, at the price of £8. Nobert often 
expressed his opinion that the last four bands of this plate would 
never be resolved by any objective; but after inspecting Col. Wood- 
ward’s photographs of the whole series of bands, he set himself to 
work to make a new plate upon which he ruled 20 bands, com- 
mencing with 11,000 lines to the inch, and ruling the twentieth at 
the rate of 200,000 in the same space. ‘The lines on the roth 
band of the new plate correspond nearly to the 19th band upon 
the old plate. The new plate can also be obtained from Mr. 
Wheeler, the cost of which is £15.
