Abstract
THIS essay, with true German thoroughness, gives a very complete, though necessarily brief, survey of the various microscopic organisms that have been obtained in pure cultivation. The organisms are dealt with in groups (and not individually), partly according to their biological position, partly according to the changes they produce. The green and blue algae and diatoms are first considered, then the bacteria—the nitrifying forms, cellulose fermeaters, sulphur bac teria, &c.—and lastly the yeasts and protozoa. In the final portion of the book the subjects of pleomorphism and systematic position of these organisms are dis cussed. The bibliography is a very full one, and it is probable that this part of the compilation will be most appreciated.
