 Geol. Soc. London 75: 226-227. 1920. — Lists the following representatives of an Arctic flora 

 found in the Pleistocene at Barnwell Station, which is correlated with the late glacial deposits 

 of the Lea Valley that contain strikingly similar Arctic flora: Thalictrum albinum L., Ran- 

 unculus hederaceus L., lingua L.f, repens L.?, bulbosus L., amplexicaulis L.?, Draba incana L.,

802. Reid, E. M. Preliminary description of the plant remains. Quart. Jour. Geol. Soc. 

 London 75: 197-200. 1920. — Gives results of preliminary study of what the authoress calls 

 the Castle Eden flora, found fossil on the Durham coast in fissures in the Permian Magnesian 

 limestone. Fifty or more species chiefly rock and bank dwelling plants are recognized of which 

 more than half are exotics showing resemblances to modern Asiatic forms; e.g., Rubus floscu- 

 losus, now Chinese, is represented. This flora is considered as older than the celebrated Cro- 

 mer plant bed and not younger (possibly slightly older) than the Teglian flora of the Dutch- 

 Prussian border. — The author calls the age Pliocene. It might be more properly considered 

 as early Pleistocene. — E. W. Berry.

803. Anonymous. Kauri-gum oil. Chem. & Druggist 92: 9. 1920. — Crude kauri-gum 

 distilled under commercial conditions in New Zealand yields an oil which is separated into 

 motor spirit, 15 per cent, a solvent oil, 15 per cent, paint oil, 30 per cent, varnish oil, 30 per 

 cent, and pitch the remainder. — E. N. Gathercoal. 



804. Anonymous. The economic resources of Burma-camphor. Chem. & Druggist 92: 

 425. 1920. — Blumea grandis, DeCandolle {Conyza grandis, Wallach), a weed, 6 to 8 feet high, 

 growing very abundantly on cut-over forest lands in Tavoy, Burma, yields a camphor reported 

 to be identical with Chinese camphor. Steps are being taken by the Burma Forest Depart- 

 ment to determine the commercial possibility of camphor from this source. — E. N. Gathercoal.
