agency, and very probably by some ship — either by a Viking, whose 

 countrymen used stones for anchors ; or as ballast, as Mr. Hughes 

 has seen other primitive boulders scattered on the coast of Norfolk. 

 What I object to most emphatically is the continual manufacture of 

 these gigantic postulates on the most fragile evidence by men whoso 

 work and gifts give them a wide audience.

I. — A Manual of the Geology of India. Chiefly Compiled 

 from the Observations of the Geological Survey. Stratigraphical 

 and Structural Geology. Second Edition, revised and largely 

 re-written by E. D. Oldham, A.E.S.M., Superintendent, Geo- 

 logical Survey of India. Published by Order of the Govern- 

 ment of India. 8vo. pages i.-xxiii. and 1-543. With several 

 Plates and Woodcuts, and large Geological Map. Calcutta and 

 London, 1893. 



THE first edition of the "Manual of the Geology of India," 

 published in 1879, consisted of two thick Parts or volumes, 

 and a large map, by H. B. Medlicott, Superintendent, and W. T. 

 Blanford, Deputy Superintendent, of the Geological Survey of India. 

 This was followed in 1881 by Part III, on the "Economic Geology," 

 by V. Ball, Officiating Deputy Superintendent ; and in 1887 by 

 Part IV., "Mineralogy," by F. E. Mallet, Superintendent of the 

 Geological Survey of India. 



The Parts I. and II. above-mentioned were carefully reviewed in 

 the Geological Magazine, Decade II. Vol. VII. 1880, pp. 79-85 

 and 127-134. The important conclusions arrived at by Messrs. 

 Medlicott and Blanford, from the geological researches made and 

 recorded by themselves and their colleagues in the Survey, were 

 noticed in detail in the review alluded to above, and were shown 

 in classified tables taken from the " Manual," especially as to the 

 successional formations, severally in " peninsular " and " extra- 

 peninsular " India, with their approximate thicknesses, charac- 

 teristics, geographical range, local types, and foreign equivalents, 

 as far as then known. 



The labours of the Survey since that time (1879) have been 

 continuous and successful in many directions, as its rich and well- 

 conducted " Palaeontologia Indica" (many volumes in Series 4, 9, 

 10, 12, 13, and 14; with an Index, 1892, to the whole issue), and 

 its "Memoirs" (vols, xviii. to xxiv.), fully prove. 



In the title-page of this new Number of the " Eecords " (the 

 "Manual of the Geology of India— stratigraphical and structural — 

 second edition, revised and largely re-written, pp. 543, with numerous 

 tables and geological maps. Eoyal 8vo. half-calf, 1893. 16s."), 

 unfortunately, the names of the original authors have been omitted, — 

 apparently by inadvertence, we must suppose, for one of them is 

 mentioned at page x. as having assisted in the preparation of this 

 second edition. This omission is greatly to be regretted.
