less conformably on the underljhng metamorphic series, and shares with the 
latter in the general folding and disturbance of the strata. 
In one or more of the folds of metamorphic rocks shown in the section, fig. 1, 
1 found inclosed and folded into a narrow strip a mass of limestones, calcai'eons 
conglomerates and shales, here and there silicions, which at once reminded me of 
the Cambrians of the northern slope of the Himalayas. Thoi’o the conglomerates 
consisted entirely of quartzites, the same as the cementing matrix, and formed 
with the latter a very hard jasper-like rock. Here the conglomerates are a hard 
grey, silicions limestone, pebbles as well as matrix. I believe that the Bageswar 
limestone really represents a limestone facies of the slate series or Cambrian; and 
in connection with the folding of the metamorphic series I consider them part 
of the same marine development of the Cambrians, now severed fi’om the strip 
north of the central fold by the erosion of the upper arch of the anticlinal. 
As indicated in the sketch section, fig. 1, I include the Naini Tal (Cheena) 
limestone for the present in that old Cambrian formation. Though the relations 
of this rock to the neighbouring tertiaries and basaltic traps is not quite clear’, 
it seems best for the present to class them with the Bageswar rocks, 'with which 
they have much in common. The Naini Tal beds seem to dqr below the meta- 
morphics, hut in reality rest above them and merely conform with them in a 
curve, which, as nearly all the larger ones in this section, have lost the upper arch 
by denudation, as showrr in the above-mentioned sectiorr. It is needless to state 
here that the Naini Tal lindestone has been compared with the Krol limestone of 
Simla. 
3. The Pre-Silurian roeJes of the Peninsula. —In Central and Southern India 
there is found a formation, covering the metamorphies in patches, and in some 
places overlaid by the Vindhian sandstones. Various are the strata occupying 
this position between these two rock gronj)S, though mostly silicions, here and 
there calcareous, with hods of conglomerates, and as yet helicvcd to ho wholly 
unfossiliferous. Last year whilst traversing the Vindhian range on the Sonc 
river, I observed a series of rocks, jasper-like conglomerates, quartzites and 
grey, almost crystalline limestones underlying the lower Vindhian sandstone near 
Agori Khas, which afterwards I could not help but compare with the .similar 
rocks of the Himalayas. Here as there they rest directly on the metamorphic 
rocks. 
4. The Palceozoio roofes of the Himalayas; Silurian to Garhoniferous. —Directly 
resting on the Cambrian slate series I found a group of rocks as follows :—
