352 SUMMARY OF CURRENT RESEARCHES RELATING TO 



great number of the larger fungi, with special reference to their edible or 

 poisonous qualities. He devotes one chapter to the cultivation of mush- 

 rooms. A number of recipes for cooking them are given by Sarah 

 Tyson Rores. The Chemistry and Toxicology of Mushrooms is added 

 by J. F. Clark. The results of Atkinson's analyses correspond with those 

 arrived at by European chemists, and all prove that the fungi are much 

 less nourishing than they were at one time supposed to be. The poisons 

 found in fungi are also described. The author adds a key for the deter- 

 mination of the genera.

Immunity from the Poison of Fungi.* — Rene Ferry has experimented 

 with the poison of Amentia phalloides on rabbits, in order to discover a 

 cure for the cases of poisoning that occur through eating this fungus. 

 He found that iodide of potassium was not so effective as it was supposed 

 to be. He then tried immunising animals by repeated doses, and he not 

 only rendered these animals immune, but the serum had the effect of 

 rendering other rabbits immune. It had, however, no effect as a 

 curative agent, and the author considers that such a serum may be 

 neglected, considering the comparatively few cases of poisoning that 

 occur. 



Abnormalities in Fungi.f — J. Lutz describes some cases in which 

 supernumerary hymeniums are formed in the larger fungi. A certain 

 number of cases, he considers, are explained by the close contact and 

 attachment of two fungi at an early stage of growth ; the more vigorous 

 plant pushes ahead and hoists the less developed individual with it, 

 sometimes carrying it reversed on the pileus or attached to the edge. 



Technical Mycology .J — Franz Lafar has published a further 

 instalment of his Handbook of Technical Mycology for technical and 

 agricultural chemists, brewers, etc. Part III. is a continuation of 

 part I., and concludes the work of Lindau on Eumycetes. The author 

 describes the anatomy and physiology of fungoid hyphas and cells, and 

 discusses reproductions in fungi entirely from Brefeld's standpoint, that 

 no sexuality exists among the higher fungi, agreeing thus with Dangeard. 

 He regards the Mucor sporangium and the ascus as closely related. 



Hugo Fischer-Bonn gives the chemistry of fungi and bacteria, both 

 of cell-membrane and of contents. The subjects of assimilation and 

 metabolism are dealt with by W. Benecke. Alfred Koch, L. Hiltner, 

 P. Miquel, M. Hahn, A. Spickermann, S. Winogradsky, and H. Jensen 

 tell what is known of the various processes of nitrification and nitrogen 

 assimilation, the action of acids, etc. Cladotrichere, Streptotricheai, etc., 

 are described by W. Rullman.
