2. Jurassic Fish-Fauna in the Hawkesbury beds of Neio South 

 Wales. An abstract of a memoir by A. Smith Woodward 



{Annals and Magazine of Natural History, Nov. 1890), mentions 

 the discovery of a lai-ge collection of fossil fishes in the Hawkes- 

 bury series of Talbralgar, New South Wales, which prove to 

 represent a typical Jurassic fish-fauna. The genera identified 

 include Coccolepis and Leptolepis, also new forms allied to Semio- 

 ?iotus, to the Dapedioids and to Leptolepis, respectively. Another 

 paper describes an early Mesozoic fish-fauna discovered some 

 years ago in the Hawkesbury beds at Gosford, N. S. W. 



3. On the state of Alpine glaciers in 1 889, by F. A. Forel. 

 — In 1889 the commencement of a forward movement was 

 proved in the case of two glaciers of the first rank, the Rhone 

 glacier and the Glacier des Bois at Chamounix, as well as of two 

 or three small glaciers of the Ortler group. The number of 

 glaciers, now on the increase, has become 55 tor the whole Alps, 

 distributed as follows : all the glaciers of Mont Blanc ; a large 

 proportion of glaciers in the Bernese and Valais Alps ; some 

 isolated glaciers in the Pelvoux region (Dauphine) and in the 

 Ortler (Tyrol). With the exception of the Ortler group, all the 

 glaciers of the Austrian and Grison Alps are still receding or are 

 stationary. — Bibl. Univ., Ill, xxiv, 87, 1890. 



4. Cordierite as a contact mineral. — Y. Kikuchi has studied 

 certain cordierite rocks of Japan, from the bordering region of 

 the provinces Koclsuke and Shimotsuke, along the Watarase- 

 gawa. The cordierite occurs here in slate as a product of con- 

 tact-metamorphism with granite. It shows various peculiarities 

 of form and structure, and is especially characterized by the 

 presence of symmetrically arranged inclusions of black carbona- 

 ceous matter. It is thus strikingly like the variety of andalusite 

 called chiastolite, and the author proposes to call it cerasite, from 

 Kepaffo? cherry. This word alludes to the Japanese name 

 Sakura-ishi, or cherry-stone, locally given to the cordierite slate, 

 because the structure of the stellar aggregates of the cordierite 

 resembles a cherry-blossom, and also from the same resemblance 

 in a similar rock where the forms are now only pseudomorphs.

5. iSanguinite, a neio mineral. — Dr. Miers has given the name 

 Sanguinite to a mineral found upon specimens of argentite from 

 Chanarcillo, Chili. It occurs in minute hexagonal scales, optically 

 uniaxial. The color is dark red and the streak dark purplish 

 brown. Qualitative trials make it probable that the mineral is a 

 sulpharsenite of silver, allied to proustite, with which it is asso- 

 ciated, but with which it cannot be united. — Min. Mag., ix, 182.
