It is iiseless to endeu- vor to study these minute bodies without the aid of the very best optical appliances possible, and with the most carefiil treatment of the material. A Zeiss — or etiually good — Ajiochromate of 2 mm, with an Aperture of , is an absolute necessity. A lesser apperture will not suffice. Moreover an oil inmiersion condenser in the substage must be used, the common Abbe coudeusers do not give a sufficiently perfect light to enable one to see the neeessaiy details. And lastly, the ordinary daylight is not suitable, being neither sufficiently pure, nor steady enough to always give the same rcsults. In these investi- gations I have used exclusively the achromatic light-filter described.
