A second group nearly allied to the Algse (Frotococcacea) is that of the Volvocin'uke. These organisms consist of colonies of cells united by a common gelatinous substance, and the following characteristics indicate their close relationship to the Algai:—(1) in the inactive stage tliQy possess a cellulose membrane; (2) they exhale oxygen; (3) they possess an abundance of chlorophyll and of vegetable red or brown coloured Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Claus, Carl, 1835-1899; Metcalf Collection (North Carolina State University).
