The mass of evidence brought together in this elaborate paper, which 

 treats of (I.) India, (II.) South Africa, (III.) Eastern Australia, (TV.) 

 the Salt Range, and (, V.) Europe, demonstrates, according to the author's 

 interpretation, that a glacial period appeared with great intensity in, 

 upper carboniferous times on a continent, the greater part of which lay 

 south of the equator, but which, later in the Permian period, extended 

 itself over the greater part of the globe : and that, though many ice-made 

 formations have been mentioned in geological literature as being of 

 earlier or later age, at no time can such deposits be shown to have had 

 such a wide extension as in the Carboniferous, or in the Quarternary 

 periods. 



Mr. R. D. Oldham gave a much needed and valuable paper, in the 

 August part of the Records of the Geological Survey of India, on the 

 " Sequence and Correlation of the Pre-Tertiary Sedimentary formations 

 of the Simla Region of the Lower Himalayas;" founded on an. amal- 

 gamation, as far as is possible, of the many isolated accounts which 

 have been published of different portions of the range since the publi- 

 cation of the Manual of the Geology of India in 1879. He gives the 

 folio wing sequence, in descending order : —
