 „bastard" Logwood. (Bull. Torrey Botanical Club. 

 Vol. XXXI. July 1904. p. 367—377. 2 Fig. in text.) 



„Bastard" logwood, whichyields littleorno Haemotoxylin, isto 

 beregarded as a variety oXHaeinotoxylon campechianum. Thechemi- 

 cal differences between the two are slight, but the „bastard" wood 

 shows a lower carbon content, perhaps owing to the absence 

 of the pigment. Seedlings agreed too closely in composition 

 to Warrant any conclusions as to differences in metabolic pro- 

 cesses in the two varieties. H. M. Richards (New York).

 tural Orders, Amarantaceae, Chenopodiaceae and Poly- 

 gonaceae. (Agricultural Ledger No. 6 of 1904. Second part 

 p. 61—72.) 



Original analyses are given of the green parts of Aerua javanica 

 Juss.. Alter nanthera sessilis R. Br., Amarantus gangeticus Linn., Ama- 

 rantus polygamus Linn., Amarantus spinosus Linn., Amarantus viridis 

 Linn., Basella alba Linn., Beta vulgaris Mog., Calligonum polygonoides 

 Linn., Celosia cristata Linn., Chenopodium album Linn., Digera arvensis 

 Forsk., Haloxylon salicornicum Bunge, Polygonum barbatum Linn., Poly- 

 gonum stagninum Harn., Polygonum plebeium R. Br., and Suaeda mari- 

 tima Dumont. All the samples were from Indian sources and all are used 

 as food. Spinacia oleracea, Amarantus (all species except spinosusj, 

 Basella alba and Chenopodium album are the most nutritious; Calli- 

 gonum Cilosia, Haloxylon and Suaeda the least nutritious.
