PHYSICS OF THE GLOBE. 59 



The Dorpat Meteorological Observatory has published the 

 " Met. Beob., 1875," completing the lustrum 1870-75, and also 

 "Zehnjahrige Mittelwerthe, 18G6-75, nebst neunjahrige Stun- 

 denmitteln, 1867-75," forming the Appendix to Volume II. 

 of the Dorpat Observations. The authors, Professors A. von 

 Oettingen and K. Weihrauch, have spent great labor upon 

 the discussion of these excellent observations, especially those 

 of the wind. The volume also includes observations made 

 at Reo, in the island of Oesel. 



The first annual report (1875) of the Meteorology of India, 

 by Blanford, marks a long-hoped-for epoch in the history of 

 the progress of our knowledge of that portion of the world. 

 Hitherto the Indian observations have been strewn through 

 numerous transactions and miscellaneous volumes, but now 

 the establishment of a central office will do much to con- 

 centrate effort and increase knowledge. Blanford's folio vol- 

 ume, of 387 pp., contains a highly instructive review of the 

 physical peculiarities of India, and especially of the meteor- 

 ological stations. These latter are classified as first class, 2; 

 second class, 21; third class, 65; and rainfall stations, 198. 

 Not only are means, etc., given for 1875, but for many long 

 series of observations ; so that the volume is in some respects 

 a summary of the past previous to the start on the new ca- 

 reer now opening before him. 



A very fine feature of the India Office is the publication 

 of " Indian Meteorological Memoirs," a volume similar to 

 Wild's JZepertorium, and containing the results of the in- 

 vestigations made by the Calcutta Office. Of these mem- 

 oirs, Vol. I., Part I., containing three memoirs by Blanford, 

 is published simultaneously with the "Observations."* 



The climate of South Australia is well described, both 

 popularly and scientifically, by Charles Todd, of Adelaide, 

 in "The Observatory and Climate of South Australia." Mr. 

 Todd, as Meteorological Reporter, has been able to make 

 good use of the telegraph lines of Australia, over which he 



* Jan. 25, 1878. We cannot refrain as we go to press from calling atten- 

 tion to Blanford's Part II. of the " Meteorologists' Vade Mecnm," which is 

 just received, and is simply an elementary treatise on meteorology as exem- 

 plified in the climate of India. In this work all the errors that still disfigure 

 our text-books are dropped, scarcely mentioned, and the best thoughts of the 

 best men of 1877 are clearly set forth.
