1. PALAEOZOIC* by J. W. Salter. 
When, in 1851, Colonel Strachey read a paper before tbe Geolo¬ 
gical Society, on the Physical Geography and Geology of the 
Himalayas and Thibet,* the fossils he had laboured so strenu¬ 
ously to collect hardly drew the attention they deserved. In 
the published abstract, however, the main facts were recorded, 
and lists of genera quoted, which showed, in accordance with 
the sections, an ascending order from Silurian slates, through 
Carboniferous beds (the Devonian has not yet been detected 
in India), to a most interesting set of strata, which clearly 
represent in every way the New Red Sandstone. The fossils of 
the last-named beds, indeed, agree perfectly with that portion 
of the Triassic fauna which is developed in the St. Cassian 
beds, in the Tyrol. It so happened that these celebrated 
Alpine strata had, a short time before, attracted renewed 
attention, and their relative age had been canvassed by
