though incorporated with the Scotch collection, properly belongs to 
this head. 
Steep No. 3.— Recent Shells. 
This collection was arranged some time ago, but its place having 
been lately shifted, the arrangement has been necessarily disturbed; 
a short time, however, will bring it into order again. This series 
might be ‘easily extended if thought desirable. 
No. 4.—Organic Remains. 
It has been at different periods in the contemplation of the Society 
to form a collection of organic remains, arranged after the same 
manner as the recent shells, but this object having been considered 
secondary, it has been as yet but very imperfectly attained: it has 
also been hoped. that, in deference to the recommendation of the 
British Association for the Advancement of Science, these two col- 
lections would have been undertaken on a scale commensurate with 
their importance by the British Museum. They appear to your 
Committee to belong properly to that establishment, and they deeply 
regret that the governing body of the Museum have not begun to 
carry into. effect the above-mentioned recommendation. 
Your Committee suggest the advantage, when time permits, ot 
forming an index to the fossil shells, either according to a natural 
system, or alphabetically, so that any person may knew in what 
drawer a given species can be found without searching catalogues of 
separate formations. _ 
No. 5.—Of the Rocks of England, fossils included, arranged in the 
: order of superposition. 
This bemg by far the most important part of the collection, re-
