Not illustrated. 1918 Excerpt: ...such water may teem with animal life, just such life as the microscopist desires. It is not possible to point out the exact locality where an abundance of microscopic animals may be found. They appear to be a law to themselves. The pond that may seem a likely place, may for some unknown reason be barren; while another to all appearance worthless may prove of great value. The food-supply may be the cause, or the temperature, or freedom from enemies, or some other thing. The microscopist can take his dips to the instrument, only hoping that he has the success for which he has wished. There is one place, however, to which he need never go.

Rather thrust the dipper among the aquatic weeds, and after several gentle turns and twists to loosen the plants and to stir up the water about them, transfer the dipperful to the bottle, and hope for the best. The majority of microscopic animals may be collected in this way better than in any other, except by washing the plants and preserving the rinsing; but this is a rather more laborious method, and takes rather more time, a matter of some importance if the microscopist's leisure is limited. These methods, however, are not restricted to Infusoria. In my vicinage, certain ponds with which I am well acquainted are always entirely free from Lemna and Spirodela, while others, smaller and shallower an...
