On allergy to cottonseed oil.
The question of specific sensitiveness to edible cottonseed oil in contradistinction to cottonseed is worthy of recognition and more critical study than it has received. Discussions of cottonseed sensitiveness in textbooks on allergy generally imply that cutaneous sensitiveness to allergenic extracts of cottonseed or cottonseed meal signifies clinical sensitiveness to foods containing salad oil or vegetable shortening made from cottonseed oil. A pronounced difference of opinion concerning this concept is displayed in the testimony of six allergists who appeared as expert witnesses at a public hearing 1 in relation to label declaration of vegetable oils in salad dressings. Opportunity to study allergy to cottonseed oil is rare. 1 Hence, worthy of record are results of a concurrent comparison of two cottonseed-sensitive allergic subjects, one of whom disclaimed and the other proclaimed a demonstrable sensitiveness to edible cottonseed oil.

THE SOLUBLE SPECIFIC SUBSTANCE OF PNEUMOCOCCUS
1. Refinements in the methods for the isolation of the soluble specific substances of Types II and III pneumococcus are described. These improvements have resulted in the isolation of the end-products in a form free from nitrogen and of enhanced activity with immune serum. 2. The soluble specific substance of Type I pneumococcus is described and shown to differ sharply from the corresponding substances of the other two types, each of which, in turn, differs from the other. 3. Progress is reported on the identification of the sugar units from which the polysaccharides are built up. 4. The evidence so far accumulated is believed to favor strongly the view that the polysaccharides isolated are the actual specific substances of Pneumococcus.
