FIFTH REPORT— 1835. 
XXVlll 
Desiderata noticed in Mr. Conybeare’s Deport. 
1. An accurate examination of the conclusions deducible from 
the known density of the earth, as to the solid structure and 
composition of the interior. 
2. The attention of residents in our remote foreign depen¬ 
dencies to the two great questions of comparative Geology and 
Palaeontology. 1. Is there or is there not such a general uni¬ 
formity of type in the series of rock-formations in distant coun¬ 
tries^ that we must conceive them to have resulted from general 
causes of almost universal prevalence at the same geological 
sera? 2. Are the organic remains of the same geological period 
specifically similar in very remote districts, and more especially 
under climates actually different; or are they grouped together 
within narrower boundaries and under restrictions as to geo¬ 
graphical habitats , analogous to those which prevail in the 
actual system of things ? 
3. An examination of the geological structure of the countries 
constituting the great basin of the Indus ; where, if in any part 
of India, it is supposed a complete series of secondary strata 
may be expected. 
4. To determine, by induction, the forces which have pro¬ 
duced the elevation and general configuration of the land, and 
to investigate the dynamical laws of these forces*. 
Desideratum noticed in Mr. Taylor’s Deport on Mineral Veins. 
A correct account of the affinity that the contents of a vein 
mi 
bear to certain of the rocks in which the fissure may be situated.

Desolutions of the Committee . 
1. That a Committee be appointed for devising the means of 
forming and publishing a full and arranged Catalogue of works 
on Natural History. 
2. That a Committee be appointed to obtain an exact Cata¬ 
logue of the Animals and Plants inhabiting Ireland. 
3. That Mr. Ball be requested to investigate the mode by 
* Reports, x ol. i. p. 408. See Mr. Hopkins’s Essay on Phvs. GeoL in the
