Tobacco as a Farm Crop for Evgland. 
These two leaves were marked Zh, and were weighed and dried separately, 
but the insuflScient quantity prevented them being analysed separately from 
the others. 
The samples were dried at 100° C. and weighed, and the moisture deter- 
mined with the following results : — 
Per Cent. 
No. 1 contained 20- 7 water 
No.2 21-4 
No. 3a ,, 20-8 ,, 
No. 3b ,, 18-8 ,, 
Zb sample was then mixed with the remainder of Xo. 3a. The dried 
leaves were broken down and the mid-ribs removed. The mid-ribs were 
very bulky, and were weighed and their percentage calculated. 
Per Cent. 
No. 1 contained 30 • 4 stalks in dried leaf 
No. 2 26-2 
No. 3 ,, 21-9 ,, ,, 
The remainder, consisting of the fleshy part of the leaf, and the smaller 
veins, constituted, when perfectly dry, the samples that were taken for 
analysis. 
The ash was first determined in the usual manner by heating a weighed 
quantity to a dull red heat. The following are the results : —

The samples burnt much more readily than the previous English samples, 
although there was a slitjht difficulty in oxidizing the last traces of carbon, 
especially in No. 1. On first heating, an oil distilled off and burnt with a 
very luminous flame. No. 2 giving ofi" a very large quantity. Little or no 
self-supporting combustion was noticed except in No. 3, which continued to 
burn slightly when once ignited. It will be seen that the quantities of ash 
in Nos. 1 and 3 are high, No. 2 being fairly low. 
Complete analyses of the ash were then made with the following results : —
