for I must Ihin'k it unfair, and of course not very honourable, to make 

 the book a pretext for misrepresenting or maligning the author. 



J. L. Drummond. 

 Belfast, June 12, 1851. 



[The review in question was from the pen of a well-known botanist, 

 who is not likely to have mis-stated or coloured facts. I have neither 

 seen nor heard of Dr. Drummond's work, but intend to procure it and 

 amend my ignorance in this respect before the appearance of another 

 number. In the mean time I only ask my readers to suspend their 

 judgment. — E. N.] 



Notice of the ' Botanical Gazette,^ No. 30, June, 1851. 



Under the head 'Original Communications' Mr. Henfrey reverts 

 to his former plan of giving us in an English dress the labours of our 

 continental brethren. The title of 'original' is, however, misapplied. 

 He might as well have called the translated abstract of the paper by 

 MM. Macaire and DeCandolle on the 'Direction taken by Plants' by 

 any other name, say 'elastic' or 'waterproof Macaire's paper appeared 

 in the ' Philosophical Transactions' for 1848, and reappeared in the 

 ' Bibliotheque Universelle de Geneve' for 1849, in the latter instance 

 being accompanied by explanatory observations by Alphonse DeCan- 

 dolle. The conclusion deduced from a great number of experiments, 

 which appear to have been conducted with labour and precision, is 

 this: — "It must be through the distension of the tissue by oxygen 

 and the fixation of the carbon, that the leaves bend, curl or twist 

 upon their petioles. The cause is evident, but we do not know /low 

 it acts." 



Under the head ' Literature ' the following works are noticed : — 



' Outlines of the Anatomy and Physiology of the Vegetable Cell. 

 By Prof H. von Mohl. Brunswick, Vieweg and Son, 1851. Pp. 

 152, woodcuts and plate.'

' The Phytologist,' May, 1851.
