and Ireland. Mr Loudon (by the bye, a very remarkable man) 

 has, by the publication of these important, interesting, very 

 useful, generally' accurate, and beautifully illustrated volumes, 

 contributed to the literature of this country a work not sur- 

 passed by any within the range of our reading. To the pro- 

 fessional forester, the improver and embellisher of estates or 

 pleasure grounds, Mr Loudon''s work will afford on all occa- 

 sions useful and accurate information, for there is not a subject 

 connected with these operations, that is not to be found amply 

 discussed there ; even the amateur will consult the Arboretum 

 with great pleasure and much advantage. We do not say more 

 than the work merits, if we add, that it should form the ma- 

 nual of the professed forester and embellisher of grounds, and 

 find a place in all our public libraries, and the Hbrary of every 

 country gentleman.

We expected from a chemist of Dr Ure's celebrity, a work of 

 a superior cast, and in this we have not been disappointed. ^On

 tion of the author. The chief articles in this Part are the fol- 

 lowing : — Acetic Acid, Alcohol, Alum, Anchor, Assay, Baths, 

 and Beer. Where necessary, the descriptions of apparatus and 

 processes are amply illustrated by engravings. It is the inten- 

 tion of Dr Ure to complete the work in ten monthly parts, 

 and to illustrate it with upwards of one thousand engravings 

 in wood.

Dr Johnston has done a great service to the Fauna of Bri- 

 tain, by the pubHcation of this valuable' volume. Since the 

 time of Ellis ^the zoophytes of our country have occasionally 

 engaged the attention of observers, and their observations have 

 been laid before the public through various channels. Now,
