APABT from a few special investigations, such as that on grouse disease, little persistent attempt has been made to study the diseases of game or methods of controlling disease or increasing the health and productivity of game. The opening a few years ago of a game research estate at Knebworth by Imperial Chemical Industries Ltd. was therefore a movement of scientific as well as of sporting interest, and now a second centre has been set up at Jealott's Hill, Warfield, Berkshire, for the study of problems relating to intensive rearing and the incidence of disease. From these stations appear occasional short pamphlets dealing with the progress of research or summarizing present knowledge regarding specific diseases. Advisory Leaflet No. 12 (June 1937) deals with a few diseases of game most commonly encountered on rearing-fields and amongst wild stock, and offers some suggestions for simple treatment such as a keeper could apply. The diseases referred to are gapes, coccidiosis, cramp, pneumonia, 'sore mouth', and strongylosis or 'partridge disease'.
