2\ miles west-nortli-west of Hawes Junction, I have obtained 

 a solitary example of a phosphatic nodule. The phosphatic nodules 

 and phosphatic matrix examined show sponge spicules, but these 

 are for the most part fragmentary ; some are of crypto-crystalline 

 silica, some replaced by calcite, whilst the axial canals are often 

 filled with the same phosphatic material as the matrix. The spicules 

 are referred to hexactinellid and to monactinellid sponges. 



I am very much indebted to Dr. G. J. Hinde for notes on the 

 sponge remains, and also to Dr. W. Pollard for testing the phosphates. 



IV. — Short Notices, — In Sprawozdanie Komisyi fizyograficznej, 

 Cracow, vol. xxxvi, pp. 11, 12, Professor J. L. M. Lomnicki describes 

 a new species of Mater, E. Wisniowskii, based on a right elytra 

 found between fossil leaves in Miocene clay near Kolomea. The 

 elytra most nearly resembles that of Elater ferrugatiis, a species now 

 living in the same European region. It is the oldest fossil insect 

 as yet found in Galioia, those described by A. M. Lomnicki, the 

 Professor's father, being of Pleistocene age. The paper is written 

 in Latin, and illustrated by three text-figures. 



Bolivian Fossils and Eooks. — In Sir Martin Conway's "The 

 Bolivian Andes" (Harper, 1901) will be found appendices by 

 E. B. Newton on some Devonian Brachiopoda and incertse sedis, 

 by L. J. Spencer on Bolivian minerals, and by T. G. Bonney on 

 rock specimens collected during the expedition. The author refrains 

 from acknowledging his indebtedness to these writers on his title- 

 page, and as he does not trouble to write a preface to his volume the 

 papers are likely to be overlooked.

THE Summary of Progress of this institution for 1900 has just 

 been issued, somewhat tardily if we may judge by Sir Archibald 

 Geikie's preface, the date of which (February 28th) coincides with 

 the termination of his long period of public service. 



A considerable portion of the volume before us is taken up with 

 a description of the structure and mineral characters of the Highland 

 schists. Reference is made to the mapping of certain " Green beds," 

 which in the area north of the Tay are represented by fine hornblendic 

 schists, usually containing small garnets ; and to the characters by 

 which these altered sedimentary rocks can be distinguished from 

 the epidiorites. 



In Ireland the volcanic rocks in the Silurian series have received 

 much attention ; while in Cornwall and Devon the subdivision of 

 the " Killas," the correlation of the Lower Devonian rocks near 

 Looe, and the various "greenstones" have occupied those engaged 

 in the field. 



The Old Red Sandstone has been studied in various localities 

 from Caithness to South Wales. Especially interesting are the 

 observations on the newer granites of the Southern Highlands and
