The Quarterly Journal of Microscopical Science for January, 1882, contains: H. Marshall Ward, B.A., report on the morphology of the fungus of the coffee disease of Ceylon (Hemileia vastatrix, Brk. ard Br.), plates 1, 2, and 3. This fungus probably belongs to the Uredines; still some structures, such as the curious spore-bearirg head and the long-necked haustoria are opposed to this alliance. The history of the adult fungus from the uredospore, and the formation of the teleutospores, are described and figured.—Dr. F. M. Balfour, on the nature of the organ in adult Teleosteans and Ganoids, which is usually regarded as the head-kidney or pronephros. It would seem probable that, though found in the larvæ or embryos of almost all the lcthyopsida, except the Elasmobranchii, this is always a purely larval organ, which never constitutes an active part of the excretory system in the adult forms —Dr. K. Mitsukuri (Japan), on the development of the supra-renal bodies in mammalia (plate 4).—Pat. Geddes, observations on the resting stage of Chlamydomyxa labyrinthuloides, Archer (plate 5), some very characteristic figures of the resting stage of this strange protean form are given.—J. T. Cunningham, a review of recent researches on Karyokinesis and cell division (plate 6).—Dr. Reuben T. Harvey, a note on the organ of Jacobson.—Prof. E. Ray Lankester, on Drepanidium ranarum, the cell-parasite of the frog's blood and spleen (Gaule's Würmschen). This very interesting memoir is illustrated with several woodcut illustrations.—G. F. Dowdeswell, M.A., on the micro-organisms which occur in Septicæmia (plate 7).—Prof. Bayley Balfour, Pringsheim's researches on chlorophyll, translated and condensed (plates 8 and 9).
