local transporting agency; tliougli tliere was evidence to connect these also with 
glacial conditions. 
I did not refer these erratics collectively to any particular or post-tertiary 
glacial period, because some of them presented indications of older glacial con¬ 
ditions. My object wms to record the presence of travelled (erratic) masses, and 
the probable mode of accounting for them, rather than to establish their chrono¬ 
logical relations, or advance theories regarding glacial conditions in the Punjab. 
I think the origin most lately relied upon for the red granite blocks in the 
direction of the Salt Range open to uncertainty, both on account of the quantities 
of these blocks locally present, and of the disintegrating nature of granites 
generally, but still more, because the conformity of the whole Salt Range series, 
long since pointed out by Mr. Theobald (Journal, Asiatic Society of Bengal, 
XXIII, 1854, p. 656) is opposed to the idea that bouldcra derived from this sci-ies 
below the nummulitic gi-oups could bo enclosed in upper members of the same 
conformable sequence of beds. 
The largest of these red granite blocks present no essential difference in their 
manner of occurrence from that of the other masses supposed to have been ice- 
borne ; they cannot be traced to local disintegration of a boulder bed below the 
Oholm zone, as this conglomerate docs not occur in their vicinity, and they greatly 
exceed in size the blocks of the adjacent cretaceous (?) boulder bed. 
Being evidently transported detrital masses, I conceive that the name “ erratics” 
is applicable to the whole of these traA-elled boulders of the Upper Punjab.'

* Having so defined tlie word erratic, Mr Wynne is, of course, entitled to the benefit of the 
explanation. According to current usage, an erratic would certainly be undei'stood to iinjily 
transport by ice, if not even an appropriation to the familiar glacial period. The essential 
meaning the word seems fitted to convey is some form of flotation distinct from the ordinary 
agencies of denudation. As meaning simply a stone not in place, the word would be of very little 
use.-—H. B. M.
