covered with the formation of clay-slate, which affords the 

 well-known quarries of Balahelish. Thus, according to 

 Dr. Macknight;, it appears, that the relative positions of 

 the great formations which occur in, the highlands of Scot- 

 land, correspond to the principles of the geognosy of 

 Werner. 



At the same meeting, Professor Jameson read some ob- 

 servations on the universality of rock and metalliferbus 

 formations, preliminary to a short account of some speci- 

 mens of a particular formation of lead-ore found within' 

 fifteen miles of Dunkeld in Perthshire. The formation ap- 

 peared to be almost the same with that which occurs at 

 Strontian in Argyleshire ; and it is therefore possible that- 

 it maybe a source of wealth to the proprietor. y-' 



At this meeting also thi^ secretary read some new and in-' 

 tcresting observations on the natural history of the common 

 Greenland whale, by Mr. Willian Scoresby, junior, of 

 Whitby ; and exhibited a correct drawing of that animal 

 by the same gentleman, differing materially from the figures 

 hitherto published.

 institutions calculated to diffuse useful knowledge. Of this 

 description is the Hackney Society. It consists of two 

 classes. First, Ordinary members, who contribute to the 

 funds, enjoy the use of the books, &c. Secondly, Honorary, 

 consisting of such gentlemen uhose association may re-;- 

 fleet honour on the society, and whose opinion of the la-, 

 hours of its members may be such as to impress them with: 

 sentiments of regard for such a mark of the society's re- 

 spect. Ladies are admissible as members. 

 ' The officers of this society consist of a president, .tw<^ 

 vice-presidents, two secretaries, a treasurer, and six com* 

 njittee, who are to be chosen from the ordinary meni*- 

 bers by ballot or^croll at every anniversary meeting. ; 



The meetings on Tuesday evenings are to be principally; 

 occupied by literary conver?ations, and reading such papers 

 on scientific or literary subjects as the society may be fa- 

 voured with.

 are to comprehend the mathematics, natural philosophy 

 and history, chemistry, polite literature, antiquities, civil 

 history, biography, questions of general law and policy,
