458 The Hon. Mr. Strangways on the Geology , &c, 
of limestone exist or not at Soikina, or in the cape between the 
Luga and Narova. Every point of resemblance of it with the 
formations of other parts of Russia will of course be valuable : and 
in Esthonia, it is probable that the coast near Reval, from its indented 
shores and isles, and the marked character of its organic remains, 
will be ground amply calculated to repay the trouble of examination. 
This should include an excursion to the Islands of CEsel and Dago. 
Each of the secondary districts of Sweden, would, if compared 
with that described in this memoir, present interesting features of 
similarity* to it, and be peculiarly useful in affording points of 
contact with the primitive rocks, to which the northern districts add 
the important circumstance of being overlaid by pseudo-volcanic beds. 
Though this is wanting in Scania, yet that province would perhaps 
be the most useful in its results, as it shews the connexions of a 
greater variety of rocks ; gneiss, white entrochal limestone, coal and 
sandstone, chalk and flint, &c. and several remarkable fossils. 
It would perhaps give a compendium of the strata of north and 
central Russia, at the same time shewing their relation both to the 
primitive and to some of the most important of the secondary rocks, 
and also allowing something like proof to be made of their 
connexions with those of the opposite coasts of Denmark, and 
through their means with those of the western parts of Europe. 
* An examination of the national cabinet of the Mint at Stockholm, and that of the 
University of Abo, Hermelin’s maps, Thomson’s travels, and the cursory view of the 
country which I have been able to make myself, enable me to make these assertions 
without hesitation.
