Professor Edith A. Roberts and Mildred D. Southwick ’26 of the plant science department reported to the Electron Microscope Society of America that they had determined that Vitamin A, heretofore thought of as being formed primarily in fish livers, was in fact formed in young plants and vegetables, in the form of carotene.  In October, the team reported more fully on their technique in “Contribution of Studies with the Electron Microscope to Studies of the Relationship of Chromoplasts to Carotene Bodies and Carotene Bodies to Vitamin A,” in Plant Physiology.
