AN attempt is being made to mount diatoms in absolutely 
solid phosphorus.

DISINFECTANTS.— W hat is the best disinfectant? Answer— 
A high degree of cleanliness. There is no disinfectant besides 
this that is perfect in its action. If not thorough it is almost 
useless. Many disinfectants only narcotize disease germs, but 
do not destroy them. 
Metuop For Dous.e INsectTIons.—The veins are first injected 
through the arteries with colored gelatine and then a differ- 
ently colored plaster of Paris is injected in the same way, fore- 
ing the gelatine before it, but as this stops at the capillaries, 
the arteries and veins can readily be distinguished. 
“ Wuat’s IN A Name ?”—In a Buffalo daily we notice that 
Prof. D. S. Av/licutt has prepared some fine slides of Sephemus 
Leconti. Our worthy secretary can well ask the above ques- 
tion. In the same paper is a description of Mr. E. H. Griffith’s 
new “ turn-table for the changing of a view without removing 
the object.” 
THe WenuHAM Buttron.—To keep the Wenham button or the 
common hemi-spherical lens in position while examining tem- 
porary mounts, fix it with glycerine or immersion fluid to that 
surface of a slide on which has been turned a wax oran asphalt 
ring, the internal diameter of which corresponds to the diam- 
eter of the lens. Invert the slide and it is ready for use. 
Tue Beautirut SNyow.—From the pure and beautiful snow, 
just fallen, Floegel has obtained living infusoria and alge, 
bacilli, and micrococci, mites, diatoms, and great numbers 
of fungi spores, also fibres of wood, mouse hairs, pieces of but- 
terfly wings, skin of larvee of insects, cotton fibres, pieces of 
grass, epidermis, pollen grains, rye and potato flour, grains of 
quartz, minute pieces of roofing tiles, and bits of iron and coal.
