combustion method ; the nitrogen by the usual methods. The results of the whole 
series are averaged in the following table :—

No sulphur applied . . 1:754 1:130 63°338 317 
In every single case the percentages of total nitrogen and albuminoid nitrogen and 
of sulphur were increased by the application of sulphate as manure. The pro- 
portion of albuminoid nitrogen to total nitrogen varied ; in the case of clover, 
grass, mustard, and maize it was decreased ; and in the case of vetches and oats 
it was increased by the application of sulphate. 
These results are remarkable, and may have an important bearing on the 
question of the frequently noticed differences in the feeding-value of pastures and 
root crops. Further experiments are being made. 
5. The Improvement of Poor Clay Soils by White Clover and other 
Leguminos. Sy Professor T, H. Mippieron, M.A. 
In the following table will be found some results obtained in six experiments 
on poor pastures in the counties of Northumberland, Cambridge, Essex, 
Northampton, Hampshire, and Norfolk. The figures give the increase in the 
live weight of sheep produced by the action of various manures on pastures. 
The soils in the first five cases varied from strong loam to clay, and the results are 
the average figures of three years. The Norfolk soil was sandy, and the figures 
for this station are averages for two years only :—
