water, and then put along with water into a still. . The oil comes 
over with the water. There are two kinds of oil obtained: a light 
oil which swims on the surface of the water, and a heavy oil which 
sinks to the bottom. The whole of the light oil separates in 24 
hours; but the heavy oil continues to subside for ten or twelve days. 
80 Ib. of fresh bark yield 24 oz. of the light oil, and 5+ oz. of the 
heavy. The product is a little diminished when the bark has been 
kept for some years before it is distilled. 
Cinnamon when first separated from the branch has an orange 
colour, and a very agreeable fragrant odour. The colour diminishes 
and the smell nearly disappears by keeping. 
Cinnamon is confined to the torrid zone. Besides Ceylon, it 
grows on the Malabar coast, in Cochin China, in Sumatra, Borneo, 
Celebes, the Isle of France, Guiana, Jamaica, and other West 
India islands. 
On Thursday, April 17, the remainder of Mr, Marshall’s paper 
was read. It was taken up with endeavouring to trace the origin of 
the terms cinuamon and cassia. Herodotus informs us that the 
Greeks adopted their term cinnamon from the Phenicians. The 
Phenicians probably would adopt the word used in India. The 
Malays express cinnamon by the phrase kayw menes, sweet wood ; 
and Mr. Marshall is of opinion that this is the origin both of the 
words cinnamon and cassia. 
At the same meeting a note by Mr. Thomas Knight was read. 
On looking over Mr. Spence’s book on Logarithmic Transcendents 
he found the very same demonstration of the binomial theorem 
which he himself had lately presented to the Royal Society. The 
paper contained some observations on Mr. Spence’s demonstration 
of a nature not to be read. 
At the same meeting, a paper by Mr. Babbage on the Utility of 
Analogical Reasoning in Mathematics was announced, but was not 
of a nature to be read. 
At the same meeting, a description of an Increaser of Electricity 
by Mr. Uppington was begun. He had invented the instrument in 
1810, had found it useful in his private experiments, and had given 
an account of it to the late Lord Stanhope, which his Lordship had 
approved of. The present description consisted of extracts from 
Mr. Uppington’s letters to Lord Stanhope. 
On Thursday, April 24, Mr. Uppington’s paper was concluded. 
As it consisted entirely of the description of an instrument, and 
referred to figures which I had not the means of seeing, it is not in 
my power to convey an intelligible account of it to my readers.
