Chemical Examination of English-grown Tobaccos. 
By Arthur Wingham, F.I.C, F.C.S. 
I. Tobacco Grown at Belmont by Lord Harris. 
I desire to introduce to the notice of chemists the results of a few analyses 
and experiments in connection with what may probably become a new in- 
dustry in this country, viz., tobacco-growing. It is a subject which is being 
seriously discussed, and in which a great amount of public and scientific 
interest is being shown. The results obtained and here recorded are puiely 
of a scientific nature and tend to throw considerable light on the subject as 
far as they go, and have been obtained by experimenting on some samples 
of English tobacco grown by Lord Harris at Faversham ; the work has been 
carried on iu the Chemical Laboratory of the Eoyal School of Mines and 
Normal School of Science. 
The English samples examined were of four distinct varieties, and were 
consequently arranged into four lots, which were mmibered 1, 2, 3, 4, and 
examined separately. 
The following table shows the average measurements and weights of 
leaves : —

No. 1 was of a uniform moderately deep dull-brown colour, rather thick 
and tough. 
No. 2 was of a light-bro^vn colour, partly green, and thin and somewhat 
slender. 
No. 3 was deeper in colour than No. 1. Thicker also and tougher. 
No. 4 was somewhat similar in shape to No. 1, but lighter in colour and 
thinner, although moderately tough. 
All the leaves were damp and unfermented. Before experimenting with 
them they were dried at 100° C. until no further loss in weight took place.

For the purposes of comparison some samples of foreign tobacco were taken 
and worked side by side with the English samples, and it would be as well 
to introduce them here. Unfortunately, these were all fermented leaves, it 
being impossible to obtain any that had not undergone fermentation. These 
samples were three in number, and were numbered 5, 6, and 7.
