rags. The crop, which had suffered from the aphis blight, was 
8 cwt. per acre, gathered in the last week of September. 
Specimen No. 3. — A small variety of the Grape-hop from the 
same district. The subsoil is the soft lower marl. The field 
has been fifteen years in plant, being manured in alternate years 
with dung and artificial manures, such as guano, rags, &c. The 
specimen was gathered at the same time as the last. Crop 10 cwt. 
per acre. * 
The hops, Avhen taken for examination, were in the ordinary 
condition as dried for bagging. In the drying of Nos. 2 and 3 
sulphur was employed, but not in that of No. 1. It is necessary 
to mention this circumstance in reference to the diff"erences which 
will be observed in their composition.! 
The water and ash in the specimens of hops were as follows : —

* For these analyses I am indebted to my friend and pupil, Mr. Frede- 
rick Eggar. They were made under my own constant superintendence, 
and I liave perfect faith in the results — Mr. Eggar having qualified himself 
for such examinations by eight months' assiduous practice in this species 
of mineral analysis. — J. T. Way. 
t It is well known to all who live in the hop districts that many hop- 
growers are in the habit of burning sulphur in the charcoal fires which 
they employ for drying the hops. The sulphur of course is converted into 
sulphurous acid, which, with the carbonic acid and heated air of the fur- 
nace.?, passes through the stages upon which the hops are placed. This
