CAUSE, AND THE Only causs. Glaciers he disowned, contending that 

 rain and rivers could do all the work very well without them. 



Although a determined opponent in a controversy, he was a highly 

 polished gentleman in his manners, and courteous to all with whom 

 he came in contact. An avenue of purple beeches down the Deane, 

 near Brookwood, will serve in memoriam to recall the author of the 

 '- Tree Lifter" and of " Eain and Eivers." — His nephew, Mr. Charles 

 W. Greenwood, is preparing to re-issue his books, accompanied by 

 his extensive scientific correspondence. 



ADOLPHE THEODORE BRONGNIART, 



MEMB. ACAD. FR., FOR. F.R.S., ETC., ETC. 



Born 14th January, 1801 ; Died 18th February, 1876. 



This illustrious French botanist has for half a century justly 

 occupied a prominent place as a man of science. He was the son 

 of Alexandre Brongniart, the famous naturalist, who died in 1847. 

 At the age of nineteen he wrote his first and only zoological paper 

 on a new genus of Crustacea. He afterwards devoted himself 

 wholly to Botany, especially to the study of fossil plants. In 1828 

 he commenced his great work. "Histoire des Vegetaux Fossiles, ou 

 Eecherches Botaniques et Geologiques " (dto. pp. 488, illustrated by 

 16fi plates). The work was arrested by M. Brongniart's ill-health 

 when it had reached to 12 parts, and was not resumed for nine 

 years. Only three additional parts were then issued, and the work 

 remains incomplete, to the great regret of all students of Fossil 

 Botany. M. Brongniart wrote the article on Fossil Plants in the 

 " Dictionnaire d'Histoire Naturelle " (1849). He also contributed 

 numerous separate papers on Recent and Fossil Botany to the 

 Annales, etc.

Australian Geology. — We have received the first sketch of a 

 Geological Map of Australia, including Tasmania, prepared by Mr. 

 E. Brough Smyth, Chief Inspector of Mines. Although on a small 

 scale (about 110 miles to the inch), it is neatly executed, and aff'ords 

 an excellent summary of the present state of Australian geology. 

 Considerable areas are still uncoloured; but, even as now known, all 

 the three great geological periods are represented. The crystalline 

 and igneous rocks, including granite, trap, newer and older volcanic, 

 are largely developed. These igneous rocks of different ages form a 

 prominent feature of the eastern and western districts, where also 

 occur the Silurian, the Carboniferous of Palasozoic and the Carbo- 

 naceous of Mesozoic age ; but the far larger portion of the interior, 

 now explored, especially the western half of the continent, is com- 

 posed of Cretaceous and Tertiar}^ strata, either of Oligocene, 

 Miocene, or Pliocene age. The Map therefore forms a very good 

 and useful index to the relations and distribution of the different 

 geological formations as at present known on the Australian con- 

 tinent. — J.M.
