who discourses on Seaweeds. There is much of practical suggestion 

 m all these papers, but we may be allowed to regret that Prof. 

 Geddes recommends "Grant Allen's bright papers" without any 

 caution as to the want of accuracy which mars their usefulness, 

 if not their "brightness." 



Dr. Thomas Morong died at Boston, Mass., on April 26th. He 

 was born at Cahawba, Alabama, on April 15, 1827, and successively 

 adopted the legal and clerical professions. An early affection for 

 botanical pursuits developed in later life into an enthusiasm which 

 found its outlet in the study of the Naiadacece, in connection with 

 which his name will be more particularly associated, and, in 

 1888-90, induced him to undertake an expedition to Paraguay, 

 where he made a valuable collection of plants, sets of which have 

 been distributed. He published numerous papers on Potamogetons, 

 the most important being the memoir on The Naiadace® of North 

 America, issued in 1893, and noticed at some length by his corre- 

 spondent, Mr. Arthur Bennett, in this Journal for that year. 

 Fuller biographies will be found in the Botanical Gazette and in 

 the Bulletin of the Torrey Club for June last. Mr. Arthur Bennett 

 sends us the following note:— "In May, 1880, Mr. Sandford, of 

 U.S.A., told me Mr. Morong was desirous of exchanging notes on, 

 and specimens of, Potamogeton. His first letter to me bears the 

 date of June 14, 1880, and from that time until within a few 

 months before his death our correspondence was kept up. The 

 amount of knowledge of Potamogeton and allied genera shown in 

 his letters is most remarkable, so much so, that they may be said 

 to form a text-book of the genus. When we first corresponded, he 

 lived at Ashland, Mass.; and his letters thence were not only filled 

 with notes on the genus, but with local notes, on his home and 

 surroundings : during his travels in South America his letters were 

 most instructive." Dr. Morong is succeeded in the curatorship of 

 the Columbia College Herbarium by Mr. T. H. Kearney. 



The Monograph of the Mycetozoa founded on the collections in 

 the Herbarium of the British Museum, on which Mr. Arthur Lister 

 has for some time been engaged, is now all in type, and will be 

 published in the course of a few weeks. It will consist of some 

 230 pages of letterpress, and 80 plates from the author's original 

 drawings, besides woodcuts of the genera incorporated in the text. 

 Mr. Lister has so long studied these minute organisms, and kept 

 many of the species under constant observation, that he possesses 

 exceptional opportunities for determining the value of the different 

 forms. He has besides examined the principal authoritative col- 

 lections in Britain and on the Continent, and has r« coived authentic 

 specimens from America, where this group has lately received much 

 attention. Of the 275 species which he recognise.-, lie has examined 

 authentic specimens of 175, and has drawn up his descriptions of 

 the species and varieties from the material he has examined. The 

 monograph will consequently be of special value, and must form the 

 basis of future work m these organisms. The production of the 

 plates by the collotype process has greatly reduced the cost of the 

 volume, so that it will be published at a comparatively small price.
