 Having given a comparative study of the morphological characters 

 of these genera, Dr. Cavers Sketches out the phylogeny of the 

 whole group, and gives in a pedigree table a summary of his views 

 as to the relationships of the genera to one another. A. Gepp. 



Dixon, H. N., Brachymeniurn turgidinn Broth. n. sp. (Journ. 

 Bombay nat. Hist. Soc. XIX. 2. August 1909. p. 536—537.) 



The author gives a description of Brachymeniuni titrgidum, 

 a new moss gathered on the Western Chats of South India 

 by L, T. Sedgwick. It is a distinct species with a turgid subpen- 

 dulous capsule, and with the internal lamellae of its peristome teeth 

 very strikingly developed. A. Gepp. 



Dixon, H. N., Some "Neolithic" moss remains from Fort 

 William. (Ann. Scott, nat. Hist. 74. Edinburgh. April 1910. 

 p. 103—111.) 



The author gives an account of a collection of moss fragments 

 washed out of sandy peat from under the 25-foot raised beach near 

 Fort William in Scotland. Thirty six species were identified, 

 the fragments being in a very fair State of preservation. Unlike 

 other such collections, this one is distinctly not a paludal or 

 a peat-moss association. None of the species are exclusively paludal. 

 Some grow on wet rocks or by mountain streams. Other on dry 

 boulders. Several belong to the woodlands. The presumption is that 

 the present association came from near a large stream which tum- 

 bled over boulders and flowed at times between wet rock)?- cliffs 

 down a wooded mountain side or Valley. Similar situations with a 

 moss flora almost precisely similar are to be found in Scotland 

 not many miles away. The seeds found in the same deposit indicate 

 a meadovr origin, and are badly preserved. That the climate of the 

 period was mild and equable is shown by the presence of Dicraman 

 Scottianum. Thuidium delicatulum, common in North America, 

 but unrecognised in Europe before 1874, is chiefiy western and 

 montane in Scotland. T. Phüiberti was first recognised in 1893; it 

 grows on wet mountain rocks, and, though rare, had been recorded 

 from several places in Europe and North America. A. Gepp.

Verff. unterzogen die für die Kokainbestimmung in den Coca- 

 blättern vorgeschlagenen Methoden einer vergleichenden Untersu- 

 chung. Besprochen werden 26 Verfahren, bezügl. deren Einzelheiten 

 auf das Original verwiesen werden muss. Als am einfachsten wurden 

 die Methoden von Keller, Panchaud, de Jbng (1905), Fromnie 

 und des Schwiezer Arzneibuches erkannt, welche alle im Prinzip 

 übereinstimmen. Die Alkaloide werden durch Ammoniak in Frei- 

 heit gesetzt, mit Aether aus den Blättern ausgeschüttelt, aus dem 

 Aether durch Salzsäure entzogen, durch Ammoniak wieder in Frei- 

 heit gesetzt und aus ätherischer Lösung in feste Form gebracht. 

 Hierbei werden von den Cocaalkaloiden Kokain, Cinnamylkokain,
