At the same meeting, a communication from Col. Imrie Vertical con- 

 was read, describing tho conglomerate rock of the Gram- fock oTuie 

 piaus, and tracing it from near Stonehaven to the Burn, and Grampiaos. 

 again at Callender, eighty miles distant to the N. W. The 

 position of this conglomerate rock is vertical; and of this 

 fact, in Col. Jmrie's opinion, no satisfactory explanation has 

 yet been given.-r-At this meeting, also, there was laid be- 

 fore the Society an accurate section of the coal-field at Ccal field at 

 Alloa, accompanied with interesting remarks, by Mr. Robert 

 Bald, civil engineer, and manager of Mr. Erskine of Mar's 

 extensive coalworks. The depth of the section is 704 feet; 

 the alternating strata are 141 in number; and the total 

 amount of the thickness of the different beds of coal, is 59 

 feet 4 inches. Captain Laskey likewise presented to the Fossil encrV 

 Society a cabinet containing a series of the remains of a nus * 

 fossil encrinus found in slate-clay near Dunbar. 



Mr. Leybourn of the Royal Military College, has just Mathematical 

 published the tenth number of the Mathematical Reposi- ReposU ° ry * 

 tory, containing; solutions to the mathematical questions 

 proposed in the Eighth number, and a series of new ques- 

 tions to be answered in a subsequent number; an Essay on 

 polygonal numbers; anew demonstration of the Binomi- 

 al Theorem; an illustration of the forty-seventh proposi* 

 tion of the second book of the Principia; a curious inde- 

 terminate problem; solutions to a curious problem in Dy- 

 namics; and a continuation of Le Gendre's Memoir on. 

 Elliptic Transcendentals. 



Mr. W. Moore, of the Royal Academy at Woolwich, has Treatise on 



in a good state of forwardness a Treatise on the Doctrine of fluxions ail< * 



Fluxions, with its application to all the most useful parts of tion to naval 



the true Theory of Gunnery, and other very important an . d military 



science 

 matters relating to Military and Naval Science. The 



fluxions will be preceded by such parts of the science of 

 mechanics, as are necessary for reading the work without 

 referring to other authors; and the whole will be so ar- 

 ranged, that any person moderately skilled in algebra, geo- 

 metry, and trigonometry, and having a knowledge of the 

 most common properties of the conic sections, may pro- 

 ceed to these inquiries without any difficulty. The whole 

 will be printed in 1 vol. 8vo, and will be particularly adapted 

 t£ all Military Institutions of eminence. Meteorqn
