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.

SEROLOGICAL RELATIONSHIPS AMONG AND BETWEEN THE STREPTOCOCCI AND PNEUMOCOCCI
Using the complement fixation reaction with whole bacterial solutions as antigens, it has been possible to confirm the existence, within the non-hemolytic streptococcus family, of two great groups. One of these groups, that which may be designated as of the left side, is related in an orderly way to the hemolytic streptococci; the other of the right side, is similarly related to the entire pneumococcus family. In addition, the hemolytic streptococcus family shows a reactive range which relates it, though less closely, to the non-hemolytic streptococci of the right side, and to the pneumococci. The existence of these cross-relationships is not associated with the precipitable substance of either family, but may tentatively be presumed to be dependent upon the properties of the protein or lipoid-protein fraction of the bacterial cell.
