of rocks of the Panjal system, and sometimes even of higher rocks ; 
while the older probably correspond with the Archean (Huronian 
and Laurentian) systems of Huropean geology. 
Mr. Lydekker observes, “ Most of the pink areas on the map con- 
tain representatives both of the Panjal (Older Paleozoic) and of 
the central (Archean) gneiss; in most cases no boundary can be 
traced between them; but in certain cases there is clear evidence of 
the denudation of the latter before the deposition of the former ; and 
it is consequently presumed that a similar unconformity, since 
obliterated by metamorphic action, must originally have existed in 
all cases between the two rock systems.” 
Chap. X. is devoted to the Economic Geology of the District. 
We cannot help in conclusion giving one more extract from Mr. 
Lydekker’s work descriptive of Lake Pang-Kong, which lies at an 
elevation of 13,936 ft. above the sea and is over 50 miles in length. 
“Tt may not be out of place to mention incidentally the mag- 
nificence of the scenery on the shores of the Pang-Kong lake, 
which if it were but in any less inaccessible region would attract 
crowds of visitors, whereas it is only visited by a comparatively few 
hardy sportsmen and travellers. 
The rock-scenery of parts of Lad&kh for its striking contrasts of 
colour is probably unsurpassed in the world, but when to this 1s 
added the presence of a large sheet of water like the Pang-Kong 
lake, the whole effect is then inconceivably magnificent. Standing 
at the north-western end of the lake at Lukung, the traveller has 
for the foreground a smooth beach of dazzling white quartz sand, 
some two miles in length, beyond which lies the broad expanse of 
the clear blue water of the lake, sparkling in the brilliant sun- 
light, and blending softly in the far distance with the horizon ; 
while on either side there rise up the picturesque and rugged cliffs 
of the brilliantly coloured slate rocks, bounded on the south-west by 
the more sombre gneissic crags of the higher range. 
The contrast of the white beach, of the blue water, and of the 
many-coloured barren rocks around, seen under the dazzling light 
of a sub-tropical sun, forms an impression on the memory of the 
fortunate beholder, too. deep to be expressed by words, and the 
recollection of which can never be totally effaced by any other 
scenes, be their beauty what it may ” (p. 208). 
We congratulate Mr. Medlicott, the Superintendent of the Indian 
Geological Survey, on this interesting and important volume now 
added to the list of Memoirs, and although it may be the last of 
Mr. Lydekker’s Field-work for India, since we understand he will 
‘not return again to the scene of his eight years’ labours, we believe 
he is still busy at home working out the grand series of the Sewalik 
Vertebrata to be figured and described in due course for the Palgon- 
tologia Indica, to which, as well as to these Memoirs, he has already 
so largely contributed.
