Statistical Data on the Area of Asiatic Russia, compiled by 

 Mr. W. Venuikof; translated from No. Ill, 1865, of the 

 Notes of the Imperial Russian Geographical Society, bg Mr. R. 

 Mich ell, E E. G. S., and communicated, by Lt.-Col. J. T, 

 Walker, R. E. 



[Received 13th February, 1868.] 



On his return from Asiatic Russia in 1860, Mr. Venuikof, 

 made a calculation of the surface of the Asiatic provinces of Russia, 

 with the aid of all the best maps of that period, the results of which 

 were published in a monthly Almanack of the Russian Academy 

 of Science for 1864. The figures he then arrived at have again 

 been revised and amplified by him this year, after the issue of 

 S c h w a r t z's map embracing the whole of South Eastern Siberia, and 

 the re-issue of corrected maps of Western Siberia, and of the Oren- 

 burg region. On the two last named maps, the distinct outline of 

 the Russian limits to the South and East of the Kirghiz Steppes was 

 not preserved, so that Mr. Venuikof had still to be guided by 

 the old boundaries of the Empire, as he found them in 1860. 



His authorities in his later calculations have been : — 



(1.) The General Map of Asiatic Russia, published at the Mili- 

 tary Topographical Depot in 1860, on the scale of 200 versts (133^ 

 English miles) to the inch. This map, however, only served to assist 

 him in his calculations as to the extreme northern parts of Western 

 Siberia from 65° northwards. 



(2.) The General Map of Western Siberia on the scale of 50 

 versts (33 1 English miles) to the inch, corrected to the end of 1861, 

 and to 1863, as regards the southern limits of Issik-kul. 



(3.) A similar map of the Orenburg region, corrected to 1863. 



(4.) The Map of Eastern Siberia, published at Irkutsk in 1858, 

 by which Mr. Yenuikof made a calculation of the superficial 

 extent of all those portions of Eastern Siberia which were not shown 

 on Schwartz's Map. The Western boundary of the Government 

 of Yeniseisk he drew from the map of Western Siberia, and 

 the Southern boundary of the Yakutsk region he traced from 

 Schwartz's map, so as to reconcile his calculations for the separate 

 provinces with those for the entire country.
