104 Anbury ; and the Analysis of Diseased Turnips. 
whitish-looking substance, which appeared to me like dried gas- 
lime, and I learned afterwards that on this very spot a cart of gas- 
lime had been unloaded the year before. Mr. Plumbe likewise 
pointed out to me a spot in the corner of the field : here, like- 
wise, the roots looked quite healthy, scarcely one diseased turnij) 
being seen. 
I took samples from both spots with me, and submitted them 
to analysis. 
Dried at 212"' Fahrenheit, 100 parts of each yielded the follow- 
ing results : —

No. 1 is the soil from the spot on the field where gas-lime was 
distinctly visible. 
No. 2 is the soil from a corner of the field where the turnips 
were quite sound. 
It will be seen that in No. 1 there was a good deal of lime in 
the shape of gas-lime, and that in No. 2 there was also much 
more lime than in the rest of the field where the root-crop failed 
entirely. 
Tlie larger amount of lime in the soil taken from the corner of 
the field is probably due to a dungheap, which in previous years 
had been set up on this spot. As all the other fields on this 
farm abound in lime, the manure produced on this farm natu- 
rally must contain more lime than is found in farmyard manure 
made in districts where lime is less abundant in the soil than in 
localities where oolitic rocks abound. 
I may state, in conclusion, that I have analysed one of the 
most diseased roots, and also separated the body, or more uniform 
portions of another root, from the finger-and-toe like excrescences. 
The whole root, affected very much by Anbury, yielded the 
following results : —
