3. Observations on Fossil Fegelables, accompanied by Representations 

 of their Internal Structure, as seen through thej Microscope. 

 By H. WiTHAM, Esq. M.W.S., F.G.S. &c. 4to. Blackwood, 

 Edinburgh. 

 The geological public will^feel indebted to our active and 

 intelligent friend for this interesting and handsome volume. It 

 is ornamented and illustrated with six neatly drawn, and well 

 engraved, magnified representations of fossil and of recent woods, 

 in which the structures are more correctly exhibited than is gene- 

 rally the case in similar works. The method of shewing the 

 fossil structures, by cutting the woods into thin slices, and ex- 

 amining them by the microscope, is adopted ; and although of 

 late years less employed than it ought to have been, will now, 

 we trust, from the interesting displays of internal arrangement 

 which it displays, be more generally followed. The geological 

 details in regard to the distribution and kinds of fossil wood, 

 are also deserving the attention of naturalists. 



4. The Aberdeen, Duvfdee, Leith, and London Tide Tables for the 

 year 1831. By George Innes, Astronomical Calculator, Aber- 

 deen. 



We have carefully examined this very useful annual, and 

 find it, as heretofore, remarkable for precision and accuracy. It 

 is the best work of the kind with which we are acquainted.
