it appears from the experiments of Mr. Fife, of Edin- 
burgh, and of M. Gaultier de Claubry, that Iode exists in 
sponges although in very small quantity: it is obtained both 
before and after incineration.—Annales de Chimie, &c.

Peaches growing on an Almond tree. 
Mr. Thomas Richard Knight, long known by his great 
knowledge and success in horticultural pursuits, has obtain- 
ed peaches from a sweet almond tree. The tree grew in a 
pot which contained about one square foot of earth, and was 
impregnated by the pollen of the peach. It produced nine 
peaches, the first fruit that it had borne ; three opened in 
the manner of almonds and died, the other six had all the 
characters of the peach. Mr. Knight is of opinion that the 
peach and almond are originally the same species, and that 
an almond tree, may, by cultivation, become after a good 
many generations, a peach tree.——-Annales de Chimie, &c.

A new Metal, (Aurum Millium.) 
A letter from London to a gentleman in Baltimore, an- 
nounces the discovery of a new metal by Mr. Mills. The 
writer describes the “aurum millium (as it is called) as re- 
sembling gold in colour ; very durable, and malleable, and 
not expensive, the price being 4s. a 4s. 6d. pounce. It is 
hard and sonorous, has the invaluable property of not easily 
tarnishing, and is nearly as heavy as common jeweller’s 
gold.”
