THE MYCETOZOA. and his pupils, Cooke disregarded the new light shed on the life- history of the Mycetozoa, and continued, as his predecessors had done, to regard them as true fungi. This is not the occasion to dwell on the work accomplished by Cooke for the study of fungi generally. A full account of this, with a delightful sketch of his varied and active career, is given by Mr. Ramsbottom in a memoir published in the Transactions of the British Mycological Society for 1914. A staunch supporter of De Bary's and Cienkowski's view that Mycetozoa may well be claimed as belonging to the Protozoa was Wm. Saville Kent, the author of an elaborate Manual of Infusoria. In his own cultures, he watched swarm-cells emerge from the spores of species of Badhamia, Stemonitis, etc., and saw that they fed on bacteria and would even ingest carmine granules. An interesting account of his observations appeared in The Popular Science Review for 1881, accompanied with careful illustrations. The tone of this article (which strikes one now as somewhat contentious) was due to an attack made by Cooke challenging the accuracy of his work ; but these matters, treating of " battles long ago," are now of little interest. The death only a few weeks ago of Mr. George Massee, who, like Cooke, did much for British Mycology, and who also has been such a faithful friend of our Field Club by acting for many years as referee at its Fungus Forays, comes with the sense of a great loss. His handsome Monograph of the Myxogastres, published in 1892, deals with Mycetozoa from all parts of the world, and is illustrated with twelve coloured plates. This book firings together a large amount of interesting information in a clear and attractive manner. To my father, when writing his own monograph, mentioned hereafter, Mr. Massee's book was of very great assistance. I turn now to my father's work on Mycetozoa, on which I should like to dwell rather more fully.6 He did not take up this study until middle life, but his love of nature was, I think, inborn. Even as a child, everything out of doors, the clouds and wind, the country generally, appealed to him with a strange fascination. In his pleasant home at Upton, to watch and know birds gave him rapturous delight. As a boy at school, he made a collection of mosses, but it was not until 6 Arthur Lister (born 1830. died 1908).
