of how to work, as it ensures the acquaintance of the author with 

 his subject ; thus standing in striking contrast to the odd and end 

 descriptions of supposed new species, which are poured forth year 

 after year by those who have a meagre acquaintance with literature. 

 It would be interesting to learn how many of these ' species ' are 

 valid ; perhaps thirty per cent, would be a fair estimate. 



3. Polish Geology. — We call the attention of our readers to 

 "Katalog literatury naukowej Polskiej wydawany przez Komisye 

 Bibliograficzna Wydzialu Matematyczno-Przyrodniczego Akademii 

 Umiejetnosci w Krakowie," of which, in part i, there is a list of all 

 the scientific journals published in Polish. The catalogue comes 

 out in parts, and is carried out on the lines laid down by the 

 International Catalogue of Scientific Literature Committee. 



4. Australian Tertiaries. — Messrs. Hall & Pritchard publish 

 a suggested nomenclature for the marine Tertiary deposits of Southern 

 Australia iu the Proc. Roy. Soc. Victoria, xiv (2), April, 1902. 

 They differ from McCoy, Tate, and Dennant in considering the 

 Balcombian to come above the Jan Jucian and Aldingan beds. 



5. Rugby School Museum. — In the Report of the Rugby School 

 Natural History Society for 1901 (1902), a list is given by H. A. 

 Ormerod of the local fossils now on exhibition in the Museum. 

 After each name comes the age and the locality. With the 

 exception of a few Phytic forms the fossils are all from the 

 Middle and Lower Lias. 



6. Surrey Science. — The Presidential Address of Mr. Whitaker, 

 F.R.S., to the Croydon Microscopical Club for 1901 includes a list of 

 papers on the Geology of Surrey for some years past. 



7. Stromboli. — In the Archives des Sciences Physiques et 

 Naturelles, xii and xiii, will be found two notes by A. Brun on 

 a geological excursion to Stromboli and a note on its Basalts. The 

 latter paper gives an account of the fusion-point of minerals from 

 this and other localities. 



THE GEOLOGICAL SURVEY OF ENGLAND AND WALES AND THE 

 WHITE CHALK. 



giR^ — An official memoir on " The Geology of the Country around 

 Southampton (Explanation of Sheet 316) " was received at the British 

 Museum (Natural History) about the 28th August, 1902. In this 

 memoir one reads the extraordinary statement " Offaster pilula, an 

 echinoderm characteristic of the Marsupite zone" (p. 2, chap, ii, 

 Upper Chalk). If this is true, why is there not some support given 

 to such a statement? It has been distinctly shown by Rowe (Proc. 

 Geol. Assoc, xvi (6), 1900, pp. 342, 363 ; xvii (1), 1901, pp. 55, 56, 

 73) that this urchin is characteristic of the quadratus-zone, and that 

 its occurrence in the Marsupites-zone is extremely unusual.
