11. Sawp-Baryres From Karnes, Eaypr (Proc. U.S. Nat. Museum, 
Xxxvill, 1910).—Mr. Joseph K. Pogue describes and illustrates sundry 
forms of Sand-Barytes. The figures recall to mind examples of selenite 
charged with sand-grains, the occurrence of which in the Oldhaven 
Beds has been noted by Mr. Whitaker. As the author remarks, calcite, 
gypsum, and barite are distinguished above all other minerals by the 
large quantities of sand which they can enclose upon crystallization. 
The specimens he describes were probably formed by the deposition 
from solution of barium sulphate in the interstices of loose sand during 
the consolidation of the Nubian Sandstone. 
12. Sxcrions From Deprrrorp snp Carrorp to PLoumsreap.— 
Mr. R. H. Chandler has contributed very useful detailed accounts 
of sections exposed by the two new sewers: Deptford to Plumstead 
and Catford to Plumstead (Trans. West Kent Nat. Hist. Soc. for 
1908-9, 1910). The particulars are systematically recorded and 
illustrated by map and sections. Strata from the Chalk to London 
Clay with superficial deposits were encountered; and in the low-level 
sewer from Deptford, during construction, more than 3,000,000 
gallons of water were pumped from the Chalk in the course. of 
twenty-four hours. Remains of Mammoth and Los primigenius were 
obtained from the Valley Drift at Greenwich. 
13. Fossins In THE ALGonxrAn or Scanpinavia.—In the Stockholm 
“¢Geologiska Forhandlingar”, vol. xxxi, 1909, p. 725, Dr. A. E. 
Tornebohm announces the discovery of fossils in a crystalline lime- 
stone at the northern end of the Great Arfven Lake, west of Lake 
Wener, Sweden, as well as in the Berikalk of Gudbrandsdal, Norway. 
The appearances in question have been known for some time, but have 
only recently been determined by Professor Rothpletz as calcareous 
alge. Beside these Dr. Tornebohm has found other structures which 
appear to be of organic origin. The whole microscopic look of the 
rocks is that of certain younger limestones known to be composed of 
fragments of organisms. 
14. WVicrortan Fosstns —Mr. Frederick Chapman continues his 
energetic attempt to describe the new or little known Victorian fossils 
in the National Museum, Melbourne, in the ‘‘ Proceedings of the Royal 
“Society of Victoria’. His tenth contribution contains worms and 
Crustacea, and includes Silurian Zrachyderma of two species, two 
interesting forms of Zurrzlepas from the same formation, a Ceratiocaris, 
and a Xiphidiocaris. Myr. Chapman invariably draws hjs own figures, 
and if his efforts in that direction are a little crude, we may rest 
assured that his detail is extremely accurate. 
15. Creraczous Prawrs.—Messrs. Stopes & Kershaw describe in the 
Annals of Botany, April, 1910, some pine leaves from the Cretaceous 
of Japan, and discuss their relationship with other Cretaceous species, 
and with the living forms of America. Incidentally the authors 
diagnose the genus Prepinus, Jeffrey, 1908, as that author apparently 
forgot to do so. In a second paper Dr. Stopes describes the internal 
anatomy of a leaf of Nilssonea orientalis, Heer, also from Japan. 
The result of the examination of this specimen seems to show it to be 
primitively Cycadean in character.
