♦ime of its duration, its velocity will appear to have been 

 between seven and eight miles in a second : — a velocity 

 which more than twenty times exceeds the greatest velocity 

 of a cannon ball, and can only be compared to what we at 

 present know of the amaziag velocity of electricity. 



In accounting for the nature and production of meteors^ 

 it is evident that nothing can help us in our inquiries so 

 much as a knowledge of their dimensions, their distance, 

 and the extent of space through which they move; and 

 these are only to be obtained isy good observations. Al» 

 though their appearance and the manner in which they 

 burst are very curious, and should as much as possible he 

 observed, yet an attention to these eircumstances alone 

 are not sufficient to throw much light upon them, when 

 unassisted with any knowledge of their real situation and 

 dimensions. 



XLIX. Account of New Publications, 



A Treatise on the Culture and Management of Fruit-Trees, 

 in which a veiu Method of Priming and Training is fully 

 described, &c. ^c. By W. Forsyth, F, J. S, ani

 account of it from us would be superfluous. We only tak^ 

 notice of the present edition for the purpose of mentioning 

 a new \\ay of treating diseased trees, and to extract from it 

 a testimonial highly creditable to Mr. Forsyth. 



*^ I avail myself of this opportunity (says Mr. F.) to add 

 a discovery which I have recently made, and which, as 

 being calculated to save time and labour, may deserve at* 

 tcntion. 



*' Instead of paring away the bark, as had heretofore 

 been the practice, and covering the stem with the compo- 

 sition, I now merely scrape off the loose bark, and apply 

 a mixture of cow-dung and urine only (made to the con-r 

 sistence of a thick paint) with a painter's brush, covering 

 the stem carefully over. This softens the old scabrous 

 bark, which peels off during the following winter and 

 spring, and is succeeded by a tine smooth new bark."
