Tumour Surgery and Local Anæsthesia

THE VETERINARY JOURNAL
was kept as a control, one was treated with culture filtrate, and the other two with antiformin vaccine. They received repeated doses during their pregnancy. The culture-filtrate did not prevent abortion, but the animal remained in good general health, while the control suffered considerably following the injection of virulent bacilli. Of the two injected with antiformin vaccine, one remained normal in every way, while the other, though not aborting, excreted bacilli from the vagina and udder. The author draws the following conclusion: "The experiment seems to show that vaccine treatment, carried out in the manner described, exerts a very palpable influence. Even if abortion infection cannot always be prevented, the curative effects of the vaccine will make themselves felt , and will in some degree check the development of pathological processes, and this will be manifested by a milder course of the disease with small disturbance of general health."
TUMOUR SURGERY AND LOCAL AN.IESTHESIA. By W. R. McKINNA, M.R.C.V.S. , D.V.S.M. Huddersfield. THE ease of application and the numerous excellent local amesthetics tend to make one use them in preference to general amesthesia perhaps more often than the after results justify. For use over small areas, local amesthetics are excellent in everyday surgical use, and cannot be discarded; but when used for infiltrating extensive areas, as are sometimes occupied by some tumours, one has been disappointed with the after healing of the wound, although .the operation has been carried out under strict aseptic precautions and without pain. We have noted that we have obtained much better healing of wounds after tumour removal has been undertaken under general amesthesia, and now make it a practice to discard local anresthetics when a large area is involved. In addition, those cases where a cavity is necessarily left after the removal of the growth heal with less trouble if a drainage tube is anchored in the most dependent part of the wound for several days. Such details of technique are probably generally practised by many surgeons ; we have found their benefit in our own experience.
NORMAL AND ABNORMAL GIZZARDS. By G. MAYALL, M. R.C.V.S. Bolton. THERE is little in poultry text-books on diseases of the gizzard in the fowl. Foreign bodies and inflammation of the organ receive due attention, but little else is mentioned. When one conducts a number of post-mortems a year one is struck by the variations one finds in the contents of the gizzard and in its consistency. There are times when one can only account for the death of the bird by the fact that the gizzard has failed to act physiologically and mechanically.
