CULTURE OF THE JAMROSADE AND 
It is evident from all we see and read, that at present we have merely approached 
the threshold of natural philosophy. The mind has attained some glimmerings 
which point to truth ; but it wanders discursively from theory to theory, as here and 
there a discovery has resulted from some fortunate experiment. The spirit of 
research is, however, roused ; and, if persisted in, may produce results of practical 
utility. As to glass, pending further inquiries, the wealthy man may adopt the 
green tinted medium that has been employed at Kew. The more humble amateur 
must be content to avoid expensive white glass, and trust to the shade of some 
delicate fabric, of rather open tissue, which shall produce a softened, diffused light, 
throughout the few mid-day hours of brilliant sunshine which are experimentally 
found to scorch the foliage, and scald some of the fruit near the lower surface of the 
glass. We have not profited much by the clear and beautiful glass lately introduced, 
and it is more than probable that the green-tinted glass of former years was 
productive of less injury than is the medium now so fashionable, and which facili- 
tates the passage of all the rays in the form of pure, white light. Strength and 
substance have been obtained, and so far breakage by hail has been obviated ; but 
little more can be said on the ground of utility. 
Since the above was written, the subject has been resumed in the " Gardeners' 
Chronicle " of March 4. The learned Professor has offered some apposite remarks; 
but the paper must be referred to. 
CULTURE OF THE JAMROSADE AND VARIOUS OTHER 
SPECIES OF ROSE-APPLE. 
The Jamrosade or Jambosa vulgaris of modern Botanists, is the Eugenia 
Jambos of the old catalogues, and belongs to the natural order MyrtacejE, or 
Myrtle-blooms, of Dr. Lindley's " Vegetable Kingdom." It forms a branching tree- 
like evergreen shrub, 20 or 30 feet high, with long, opposite, narrow, glossy leaves. 
Its flowers are produced in axillary, and terminal cymes, from April to June ; they 
are at first pure white, and almost destitute of fragrance ; but after a few hours, they 
become tinged with a slight yellow colour, and acquire a grateful and peculiar 
smell. The fruit grows to the size of a golden pippin apple, is very sweet to the 
taste, and emits so powerful a scent of the rose, that a single one laid in any 
apartment will fill it with its pleasant odour. 
The cultivated and wild varieties in the native country of this plant are very 
numerous, some bearing white, and almost transparent fruit, and others with every 
shade of colour up to the deepest red ; but all possess the same peculiar flavour, and 
are nearly equally esteemed by the natives. 
The plant which fruited at Chatsworth during the summer of 1847, is probably 
the same variety, which some years ago fruited with Professor Thouin, in the
