fectly hardy in the climate of England, although 
native of Nepaul, at a parallel of latitude below 
thirty degrees, which would indicate a temperatuie 
producing plants which could only be grown in this 
country by the assistance of artificial heat. This 
apparent anomaly arises from the great elevation 
of the mountain land of this portion of Asia. Here 
arise the unrivalled Himalayas, forming a moun- 
tain district, to which we are indebted for many 
splendid garden ornaments. From the accounts, 
lately received from Dr. Joseph Hooker, who is ex- 
ploring these regions in search of theii vegetable 
riches, we may expect soon to possess still more 
valuable subjects. He tells of Rhododendrons 
forty yards across, and fifty feet high ; and also of 
epiphytal Rhododendrons, growing on enoimous 
Oaks, dispensing delicious fragrance around them, 
their flowers' being as large as Lilies, four to five 
inches across. 
The researches of the botanist, for plants that 
with us may prove hardy, are not alone directed by 
parallels of latitude, although these geogiaphical 
lines may be esteemed as the primary guides of 
temperature. This is a fact, as truly observed by 
Loudon, in his Arboretum, well worthy of being 
noticed, as proving the positive advantage likely to 
acrue to any one country, from introducing into it 
the productions of every other country, however 
different they may be in geographical circumstan- 
ces. It affords a fine illustration of that law of 
Providence, by which man is enabled by labour, by 
knowledge, and researches, to add greatly to his 
stock of enjoyment and happiness,
