took up the investigation of the freshwater algaB, with which his name 

 as a botanist has become associated. He published numerous papers 

 upon these plants, and his Hist .,■>/ <>r lh itish Freshwater Alga, issued 

 in 1845 and more than once reissued, was the outcome of these 

 essays; With Hassall's public career as an analyst we are not 

 concerned; this and other matters are fully dealt with in his 

 autobiography. In 1877 his failing health induced him to settle at 

 San Eemo : here he continued his interest in scientific subjects to 

 the last — two papers on the coloration of leaves, written in 1892, 

 are appended to the Narrative — and here he died on the 9th of April. 

 He was commemorated by Berkeley in the genus Hassallia, now 

 merged in Stignnennt. 



Dr. George Bennett, whose death we briefly recorded on p. 81, 

 was born at Plymouth on January 31st, 1804, and had but just left 

 school when at the age of fifteen he made a voyage to Ceylon. On 

 his return to England he began his medical studies, and in 1828 

 became M.B.C.S. Soon after this he entered as surgeon to a 

 merchant vessel, and in the course of his voyage he visited Australia, 

 and there made some observations on the peculiar mammals of the 

 continent. He revisited that country in 1832 for more detailed 

 study of the fauna, and in 1834 published his Wanderings in Xm- 

 South Wales. Although, like most of his work, mainly devoted to 

 ornithology, this book contains a good deal of information about 

 plants, chiefly in their economical aspect. In 1836 he settled in 

 Sydney, soon acquiring a large practice, but still contrived to con- 

 tinue his natural history pursuits. A founder of the Australian 

 Museum, he afterward became its secretary, and when trustees 

 were appointed, a member of the Board of Management. Dr. 

 Bennett published numerous papers, principally dealing with 

 ornithology; his botanical contributions will be found for the 

 most part in the earlier volumes of this Journal. He was made 

 M.D. of Glasgow in 1859, and in 1860 published his Gatherings of 

 a Xaturalist in Australasia. He came to England from time to 

 time, visiting the British Museum and other places of scientific 

 resort, and always manifesting keen interest in the progress of 

 science. He was at the time of his death, which took place in 

 Sydney on Sept. 29, 1893, one of the oldest Fellows of the Linnean 

 Society, having been elected to that body in 1831. 



Thomas Lobb, the botanical collector, whose name was pre- 

 maturely included in the ir>h-i.».r-<il,i.:<i List „/• lU-ithh I!„ta,,ists, 

 died on April 30, "at a very advanced age," at Devoran, Cornwall. 

 An account of his collections and introductions will be found in the 

 Gardener*' Chronicle for May 19. 



We have received from Mr. A. H. Baird, 15, Lothian Street, 

 Edinburgh, a Craig-Christie's dissecting microscope stand, price 

 without lenses, Is. ; 3d. extra by post. A firm base supports a 

 brass rod, up and down which slides an arm of brass wire ; one end 



bent to accommodate " a three-power botanical lens." We are told 

 that, "when the arm is rotated, each lens finds the same centre," 

 but as Mr. Baird does not transmit lenses, we are unable to test this.
