ing the relation of Landlord and Tenant, and the principles and forms of

and other rural works; Minerais and Woods. By David Low, Esq., 
F.R.S.E., &e. 1 vol., pp. 680. Longman, Brown, Green, and Longmans. 
London, 1844. We consider this as an invaluable work for landowners, 
tenants, and all who are ntrusted with the management of estates ; and 
we feel satisfied that it will add not a little to the high reputation of tts 
author, Besides the portions of the treatise devoted more immediately 
to Rural Economy, there is a lucid and important section on Mineral 
Property, and more especially on the working of metals, coal, limestone, 
building-stones, dc. There is also an interesting and comprehensive 
chapter on woods, including both the culture of forest-trees, and the ge- 
neral management of wood-land.

Science. By James C. Booth, Mem. of the Am. Phil Soc., &c.; and 
Martin H. Boye, Mem. of the Am. Phil. Soc. Carey and Hart, Phila- 
delphia. Sia numbers of this work have reached us. Judging from the 
industry, research, and accuracy of the authors, we anticipate, that, 
when finished, it will contribute to the advancement of chemical science, 
and find a place in every chemical laboratory and library. The style, 
too, in which it is got up is very creditable to the American publishers.
