2. In the Records of the Geological Survey of India, Vol. xxi., 
Part 3, is an article by Dr. Waagen on the Carboniferous 
Glacial period, of much interest in connection with the 
evidence of Ice Action in Australia, which has been so 
much discussed of late. Of this more below. 
3. The Report of the Committee of the Royal Society appointed 
to investigate the phsenomena of the Krakatao eruption has 
now been published. No copy, I believe, has as yet arrived 
in Sydney, but a Review or brief abstract of its contents 
by Sir R. S. Ball appears in the Contemporary Review for 
November, and this is so accessible a periodical that it is 
unnecessary to do more than give the reference. The paper 
will be found to be of most extraordinary interest. 
4. An elaborate paper on the Mesozoic Mammalia, Marsupialia 
and Insectivora, by H. F. Osborn has appeared in the Journal 
of the Academy of Natural Sciences, Philadelphia. 
5. The Department of Mines has published in one volume, 4to, 
Report on the Mineral Products of N.S.W., by Harrie 
Wood, Under-Secretary for Mines; Notes on the Geology of 
New South Wales, by C. S. Wilkinson, F.G.S., Geological 
Surveyor in charge, and Description of the Seams of Coal

Also, Memoirs of the Geological Survey of N.S.W., Palseon- 
tology No. 1, The Invertebrate Fauna of the Hawkesbury- 
Wianamatta Serie.s, &c., by R. Etheridge, jun., Paheontologist

6. In the Bulletin of the Scientific Laboratories of Denison
