the mineral district was hardly possible. The Report still shows much 
labor. The rock strata of the lead region are described ; and consid- 
erable information of value is pisen. respecting the lead mines. Dr. 
pp appears to be inclined to the view, not hitherto admitted, that 
he lead occurs in veins, instea deposits or beds, which veins may 
be traced far below the recognised lead-bearing rocks. We shall look 
with interest for facts on this important point which the progress of the 
Survey may bring out, deferring for the present an extended notice of 
the subject.

Mr. Cook recognises in the i awen strata, three distinct beds of 
greensand marl, alternating with strata of sand; the lower marl bed is 
about 80 feet thick, and contains as fossils, Exogyra costata, Gryphea 
convera, Ostrea falcata, Terebratula Sayii, Belemnites Americanus, 
etc. The second and third marl beds are = near 50 feet thick. The 
second contains Gryphza convexa, and at one place vast numbers 
Terebratula Harlani, with other species. re the third bed, fossils are 
rare, and appear to differ in species from those below

Quebec, 1854.—No Geological Survey on this continent has been 
on with more thoroughness-and with results of higher importance aoe 
the science than those of Canada under the direction of Mr. W. E. 
gah. There is great precision in his observations, and par nce in his 
statements; and it will be a work of great honor to Canada when the Sur- 
vey is throughout completed, and the Final Report, fully inact with 
plates of fossils and sections, is published. ‘Much more time will yet
