poisoning. In reference to tuberculosis, the substance called “ tuber- 
culin,” which is extracted from cultures of the bacillus of the disease, 
has been used with the most gratifying results as an aid to diagnosis. 
Other subjects of investigation have been inflammation of the lungs 
in horses and the occurrence of cancerous and other tumours in the 
different domesticated species. Details of the results of the inves- 
tigations made will appear in due course in the Society’s Journal. 
20 . Investigations into the communicable nature of Foot-rot in 
Sheep, undertaken for the Society by the Royal Veterinary College, 
have conclusively demonstrated the contagious character of this 
affection. Professor Brown’s report on these investigations has 
been reprinted from the Joui’nal in pamphlet form, and a leaflet 
giving practical directions for dealing with the disease has been 
extensively circulated. 
21 . In the Chemical Department, the number of analyses made 
on behalf of members during the past seven months has been 547. 
A decided improvement has been noticeable in the quality of linseed 
cakes sent for examination, and the instances in which guarantees 
of “purity ” have been willingly given to purchasers have been much 
more numerous than previously. In almost all such cases the 
guarantee has been satisfied. 
22 . The usual Field Experiments have been continued at the 
Woburn Farm, and the experiments have been visited by several 
parties of agricultural students and rural schoolmasters. The 
Council will be happy at any time to make arrangements for the 
Resident Superintendent to take any similar parties over the Farm, 
and to explain to them the experiments in progress. Feeding 
experiments, both with bullocks and with sheep, will be carried on 
throughout the winter. An extensive series of experiments on the effi- 
cacy of the bouillie bordelaise treatment of potatoes in preventing 
and checking disease has just been completed at the Woburn Farm, 
and the report will appear in the forthcoming number of the Society’s 
Journal. See page 771. 
23 . The three Local Agricultural Societies, viz., the Norfolk 
Chamber of Agriculture, the Essex Agricultural Society, and the 
Royal Manchester, Liverpool, and North Lancashire Agricultural 
Society — which are associated with the Royal Agricultural Society 
for the carrying out of Field Experiments — have continued their 
work as in former years. 
24 . The experiments wffiich were undertaken by the Society at 
th« request of the Board of Agriculture upon the prevention and 
cure of “ Potato disease ” have been again carried out in six diflferent 
parts of England and Wales. The results will be published in this 
number of the Journal. See page 761. 
25 . The quality of the seeds examined by the Consulting Botanist 
during the past year was satisfactory — the germination and purity 
retained the high position reached in the previous year. Less
