Studies using dogs for both experimental and test purposes have made available much information during the past decade concerning the requirements of dogs for proteins, vitamins, fats, minerals and energy. From the list of 13 questions prepared by Dr. Harlan E. Jensen, 3 have been selected as a guide for this discussion.

It is not the purpose of this report to describe this case as an individual one because as such, it has little clinical significance. An effort will be made in this paper to describe the procedures and techniques used at the Stange Memorial Clinic in performing the canine oophorohysterectomy.

A 5-year-old horse was admitted to the Stange Memorial Clinic in spring of 1945. The horse showed marked enlargement and distention of the tortuous superficial veins on the lateral side of the foreleg in the region of the elbow joint.

Sound research study of anaplasmosis in cattle has long been conducted in hopes of discovering adequate control measures. The investigators have been numerous, have made their studies in various parts of the world where the disease occurs, under well controlled experimental conditions and under local field conditions. The approaches to solving existing problems have been directed toward phases of investigation, including both those afforded by clinical cases and by recovered carrier cases. In spite of the thoroughness exercised and the well planned investigational procedures followed, experimental results have failed to provide adequate practical control measures.
