Botany. 451 
Rev. Mr. Alexander, (a very acute and highly informed gentleman who 
is the Principal of the Lahainaluna Seminary,) on the nature and origin 
of this rock, he inforrned me that his first opinions were similar to my 
own, and that he had submitted it to sufficient examination to convince 
him that there was no Jime in its composition. This belt of rock is 
about 400 or 500 feet of perpendicular elevation above his residence, 
and about 1200 feet above the sea. , 
rom the evidence in my possession on that point, I think you may 
assume, without fear of contradiction, that no coral formation exists on 
the very elevated side,of West Maui.

Translated (with the author’s permission) by Arthur Henfrey, F.R.S., 
With an illustrative plate and numerous wood-cuts. London: 
Van Voorst, 1852, pp. 158, 8vo.—We desire in a special manner to 
commend this condensed treatise not only to botanists, but to animal 
physiologists, to medical students, and to all who would obtain a clear 
view of the present state of vegetable anatomy and physiology,—a 
knowledge of which, most interesting in itself, is almost indispensable 
to the correct understanding of the minute anatomy and physiology of 
animals. Prof. Mohl is, without question, the first of vegetable anato- 
mists, and his statements carry with them the highest authority on this 
class of subjects. We copy the short preface which he has contribu- 
ted to the English translation, as it gives a clear view of the nature 
and scope of the work.
