Field Experiments on Swedish Turnips. 
which may, like salicylic acid, reduce the number of days of 
suffering and loss of condition of the animals. 
Since the first few lines of this Paper were written the disease 
has disappeared from my farm, and every animal is in better 
health than before. The cow which had the disease the worst 
is now giving more milk than before she was attacked. I have 
also tried an experiment with salicylic acid on sheep with foot- 
rot of so bad a kind that their hoofs came off, and have found 
that they recover more quickly when that medicine is applied 
to them than from any other foot-rot remedy I had previously 
tried. 
The great importance of this discovery cannot be over- 
estimated when some 40,000 animals are known to be suffering 
at this moment from foot-and-mouth disease, and the trade in 
cattle and sheep in several counties has been almost entirely 
stopped, and that at a time when graziers in the corn-growing 
counties have the greatest number of cattle to dispose of. 
Salicylic acid can be procured from any chemist at the cost of 
Is. an ounce, or less if a larger quantity is required. 
VIII. — Field Experiments on Swedish Turnips with Soluble and 
finely ground Fhosphatic fertilisers. By Dr. Augustus 
VOELCKER., F.R.S., Consulting Chemist to the Royal Agri- 
cultural Society. 
By the liberality of His Grace the Duke of Bedford, a field 
well adapted for experiments was recently placed at the dis- 
posal of the Royal Agricultural Society for the more special 
purpose of testing experimentally, on a sufficiently extended 
scale, the comparative manuring properties of finely ground 
coprolites and other mineral phosphates and phosphatic fer- 
tilisers, in which the phosphates for the greater part are actually 
soluble in water. 
The field, which was very foul, was steam-cultivated early 
in spring, and an enormous quantity of weeds brought to the 
surface when the steam-harrows were put through the land in 
April. The steam-harrows did excellent work. The most 
level, and, as far as could be judged, the most uniform part of 
Warren-field was set apart for the swede-experiments. This 
part of Warren-field was divided into 24 sections, of one-fourth 
of an acre each. 
The whole of the 6 acres occupying the 24 experimental 
quarter-acres was surrounded by a path 2^ feet wide, and each
