From the Cape de Verd Islands I came to this place, and hoped to - 
spend part of the winter amid its southern scenery, where noble woods 
and your favourite succulents abound. M. Berthelot, one of the kindest 
of men, promises to direct my excursions, and assures me that I shall 
visit valleys hitherto untrodden by the foot of any naturalist. Armed 
with your saw and accompanied by one man, I shall explore the Laur 
groves of Ténériffe. I can hardly suppose that all the succulent plan 
which grow here have found their way into European gardens ; and this 
island is also rich in Zi/iacez, in species of Scilla and Asphodelus. There 
are also several kinds of land shells, of which I could see but three 
species in the Cape de Verd Islands, and a single fluviatile shell. 
On the increase of temperature in the Flowers of VICTORIA REGIA. 
— Translated from the ‘ Neue allgemeine deutsche Garten- und Blumen- 
zeitung’ (New German Garden and Flower Gazette, by EDWARD 
Orro, Curator of the Botanic Garden at Hamburg). Part M. í 
7th year, 1851. 
At the request of Professor Lehmann, who thought he had formerly 
. noticed an increase of temperature in the flowers of Nymphaea alba at 
. the moment of opening, as compared with that of the surrounding 
. atmosphere, we made experiments in this garden (the Hamburg | 
. tanical Garden) with the Victoria regia on the 24th of Sipieteban 
(1851), which produced the following striking results. 
The temperature in the hothouse being 173? Réaum., and that of 
tank being 163? Réaum., the thermometer on being sive into the 
flower at the moment of expanding its anthers, at 7h. 11min. p. m» 
rose to 214° Réaum., the bulb being placed among the anthers. On 
_ being sunk into the blossom below the anthers, a decrease of tempu 
= tire took place gradually. 
—. In thus preliminarily noticing the above fact, we deem it proper to 
say, that owing to the number of visitors who crowded to see the plant 
in flower, it was impracticable to pursue the experiment any further. 
_ It was made on the fourth flower that had opened. On a subsequent
