    SOME OBSERVATIONS THE SiiiaCTURE AND DEVELOPMENT OF VOLVOX GLOBATOE, AND ITS RELATIONS TO OTHER UNICELLULAR PLANTS. ^ By geo. busk, Esq., F.R.S. (Read May 26, 1852.) Three forms, or, as they are commonly regarded, species of Volvox are described and figured in Ehrenberg’s great work, and have been noticed by other observers. These are V.glo- bator, V. auT&us, and V. stellcitus. A fourth very similar or- ganism has also been described under the name of Sphcerosira Volvox. As I regard the three first named of these at all events, merely as forms or phases of one and the same species, the following observations will apply in some respects to all of them. They have more particular reference, however, to the common form of V. globator, which happens to be that most accessible to me. This beautiful and well known object, which was first noticed by Leeuwenhoek, received little satisfactory elucida- tion until it fell under the observation of Ehrenberg, whose account of its structure and notions respecting its natu’re have been adopted by most subsequent observers, and have been received with little opposition until very lately—in fact until the beginning of last year. At that time Professor William- son read a paper on the subject before the Manchester Lite- rary and 1 hilosophical Society, which is published in the 9th volume of their Memoirs. Professor Williamson’s observations have led him to con- clusions in many points opposed to those arrived at by l^hrenberg, and especially are they confirmatory of Siebold’s
