3. Tae Waxariev Disrricr, New Zeatanp.—Professor James Park, 
in his Presidential Address to the Otago Institute, 1909, on the origin 
and history of the Wakatipu District, deduced from the facts observed 
by him in the course of his survey that probably in the Pleistocene 
Period the southern portion of the South Island of New Zealand had 
been covered by an ice-sheet, some 7500 feet in thickness. ‘That is 
to say, there has been an Ice Age in New Zealand similar to that in 
the Northern Hemisphere. 
4. Tue Temreratore oF THE Harte anp Harra-MovemMEentTs.—The 
Government of New Zealand has placed £200 at the disposal of the 
Philosophical Institute of Canterbury, New Zealand, to enable that 
body to investigate the temperature of the earth’s crust and other 
geophysical and geological phenomena rendered possible by the 
construction of the Arthur’s Pass Tunnel. It is further announced 
in the Proceedings of the New Zealand Institute that the Government 
are taking practical steps to erect bench-marks at suitable places along 
the coast. 
5. Tuer Tertiary Beps or Norru-Wesr Gurmany.—Dr. A. v. Koenen 
has brought together the latest information on the Tertiary of North- 
West Germany originally investigated by Beyrich fifty years ago. 
His pamphlet (2 Jahresber. Niederstchsischen geol. Ver. su Hannover, 
1909) sketches the Paleeocene, the Oligocene, and the Miocene, and 
gives a list of fossils from Volpriehausen, with annotations as to 
similar occurrences in the Scaldisian and the English Crag. 
6. Tue Geotocy or rHE WarersBere Trn-FIeLps, by H. Kynaston, 
E. ‘I’. Mellor, and U. P. Swinburne, forms No. 4 of the Geological 
Survey Memoirs of the Transvaal Mines Department, 1909. The ore 
occurs as Cassiterite. The geological structure of the country is 
comparatively simple. The central plateau is formed of the Upper 
Sandstones of the Waterberg system and the outer rim by the high 
ranges of granite and felsite which form the watershed between the 
Stark River and the Nyl and Magalakwin. Excellent coloured maps 
and sections accompany the paper. 
7. Tue Copper, Trin, anp Srrver Deposirs oF PrrKARANTA ON LAKE 
Lapoca form the subject of the Bulletin de la Commission Géologique 
de Finlande, No. 19( November, 1907). The report is written by Otto 
Triistedt, and occupies 334 pages. Many figures of rock-structure 
are given, and several plates are devoted to illustrating ‘‘ Kozoon- 
Serpentine Zones”. There is a colonred map, a table showing the 
output of the mines since 1814, and a list of all minerals recorded. 
8. Tur Miocene or AsrortA AND Coos Bay, Oregon (U.S. Geol. 
Surv., Prof. Paper 59, °1909).—Dr. W. H. Dall has reprinted 
twelve papers by previous authors on the same subject because of 
their inaccessibility to students living in the Pacific States. Happy 
students! And generous Government! The work itself is produced 
in Dr. Dall’s customary careful style, and is well illustrated by twenty- 
two plates of fossils, text-figures, and map. Many new forms are 
described, the validity of several genera is discussed in detail, and 
a further description of the fossil sea-lion (Pontolis magnus), by 
F. W. True, is appended, and illustrations of its skull are given.
