memnon aud Sarpedon (and probably Brathycles), which feed on ciii- 

 iiamon aud sour-sop : the chrysalis is smooth, the head bluntly biftir-"' 

 cate, the thorax prolonged into a point aud the back nearly straight ;' 

 whereas all the others are more or less bent into an angle : they differ 

 also in position, being suspended to the undersides of leaves with the 

 head downwards, whereas all the others are attached to the stems of 

 plants with the head upwards. 



I cannot at this moment call to mind what the larvae are like ; it , 

 is several years since I saw and drew them (with many others), aria ' 

 my wife painted them. They are, or were, in the British Museum, 

 placed there by Dr. Templeton ; you can refer aud see, if you wish 

 to follow this up. 



Lastly, P. disshnilis carries its name with it into the chrysalis state : 

 it is unlike any other, being indeed sxii generis : it precisely resem- 

 bles a piece of burnt stick, very elongated and ending abruptly as ft" 

 were ; head hardly bifurcate ; thorax distinctly so. 



Papilio Antipathes has only been captured once to my knowledge 

 in the island, I therefore know nothing of its transformations. Be- 

 sides this one which is in my collection, I saw two specimens only, 

 aud those on the road between Ambegammoa and Yatteantotte in the 

 hills.

Principles of the Anatomy and Physiology of the Vegetable Cell. By 

 Hugo von Mohl. Translated by Arthur Henfrey, F.R.S. 

 &c. Van Voorst, 1852. 



Somewhat late in the day perhaps, but still we hope not too late, 

 we call the attention of our readers to the above most valuable con- 

 tribution to the science of vegetable physiology. There are others 

 who have made more noise in the world, but perhaps no continental 

 botanist has contributed so much, by careful, painstaking, and con- 

 scientious research to the development of his subject, and there is 

 certainly none whose voice deserves to be more attentively listened to 

 than Hugo von Mohl ; — a man of facts, whose theories have been his 

 humble and useful servants, not his masters. It is hardly necessary 

 for us to point out in addition, that Mr. Henfrey' s name, as the trans- 

 lator, not only secures the fidelity of interpretation of Von Mohl's 

 ideas, but is sufficient assurance that the doctrine of the vegetable 

 cell is here at the level of the present state of knowledge. 



As an admirable exposition of that doctrine, we cordially recom- 

 mend it to the English reader, and regarding it in that point of view, 

 there are one or two matters on which we shall venture to offer a few 

 words of criticism. 



The first of these is the very common notion which prevails, we 

 might say among all botanists (with the exception of Von Mohl), | 

 with regard to the respective activities of the two great morpholo- 

 gical elements of the vegetable cell, — the cellulose membrane, ahd"tti4 ,* 

 nitrogenous primordial utricle.
