Die Versuche sind noch nicht abgeschlossen, die Ergebnisse noch 

 nicht völlig einwandsfrei, so viel scheint aber sichergestellt, dass das 

 Blut der Kaninchen auf wiederholte Einführung von Bohnen-, Erbsen-, 

 Linsen- und Wickenmehl durch Erzeugung spezifischer Präcipitine reagirt; 

 dass es sich dabei um charakteristische Verbindungen, wohl Eiweissstoffe, 

 der verschiedenen Arten handelt, ist anzunehmen. Hinsichtlich des VVicken- 

 mehles glaubt Bertarelli selbst Verfälschungen von 1 : 1000 mit seiner 

 Methode nachv/eisen zu können. Hugo Fischer (Bonn). 



Broadway, W. E., Report on the Botanic Station, 



Grenada, 1902 — 03. (Imperial Dept. of Agriculture lor 



the West Indies.) 



A summary of the Work carried on at the Station for the year. 

 Amongst the items of economic interest the flowering of the Lagos sük 

 rubber {Fnntumia elastica), and the continued fruiting of Para rubber 

 {Hevea braziliensis) and Central American rubber (Castilloa 

 elastica), are noted. Sierra Leone coliea {Coffea sfenophylla) flowered 

 and truited freely. Over 8 000 economic plants were sold or distri- 

 buted free. W. G. Freeman. 



Carter, W. E. H., Peat Fuel, its manufacture and use. 

 (Bulletin No. 5. Bureau of Mines, Ontario, Canada. 1903. 

 p. 1—45.) 



The author describes the value of peat for fuel, the use made of it 

 in various countries, and the methods employed in its coilection and 

 preparation for the market. Representative peat bogs of Ontario are 

 described with notes on their constituent plants, and chemical analyses 

 of their peats at various levels. The methods in Operation in Ontario 

 of Working the bogs and making peat fuel are described with füll details 

 as to machinery. Ontario possesses enormous areas of peat bogs and 

 recent events in connexion with the importation of coal into the colony 

 liave rendered the utilization of these reserves of fuel a question of great 

 economic importance. 



The Bulletin is well illustrated throughout. W. G. Freeman.

At certain centres along the railway where bananas are unloaded, 

 large quantities of banana trash (dry leaves) accumulate. The ash of this 

 is shown to contain 6,86 per cent. of potash, and 3,23 per cent of phos-
