Abstract
THE report of the Ontario Research Foundation for the year 1940 includes the Director's report together with the financial statment and a full list of publications to December 31, 1940. The Director's report refers to the new problems created for those engaged in agriculture, particularly to work concerned with remedying the slow depletion of the soil. The Foundation is studying areas which show evidence of trace–element depletion and also characteristic deficiency diseases, such as boron deficiency in the apple, sugar beet and turnip, copper deficiency in the onion and manganese deficiency in oats. A survey of land values in rural Ontario and their relation to soil, climate and economic factors has been commenced. The work on mastitis in cows has continued throughout the year and evidence has been secured proving that the leucocytes present in milk can destroy the characteristic bacteria which are associated with mastitis. A study of the pathological changes in the udder of the cow caused by tuberculosis and other diseases has been commenced.
