It is our purpose in this paper to present certain observations on intestinal tuberculosis based on 1,000 consecutive autopsies performed at the Philadelphia General Hospital during the last six months of 1933, and to describe an x-ray procedure which we hope may be helpful in the clinical diagnosis of the disease.

In many instances it would appear that symptoms and physical signs may be indefinite even in the presence of advanced intestinal disease. Clinically, therefore, the diagnosis is seldom made with any degree of certainty, although it is presumed to exist in many cases. Numerous pathologic studies show a consistently high
