The University's introductory economics course is no longer the most heavily subscribed course, according to spring-term figures released yesterday by the Office of the Registrar.

Humanities 103, "The Great Age of Athens," heads the list with 799 students enrolled, and Economics 10, "Principles of Economics," is second with 782 students.

Ec 10 was the most popular course in the fall, but lost 50 people and slipped into second place.

Otto Eckstein, Warburg Professor of Economics and the principal lecturer in Ec 10, said yesterday that because of the drop the reading list committee will take an "extra hard" look at the course's reading.

John H. Finley '25, Eliot Professor of Greek Literature Emeritus and the lecturer in Hum 103, said yesterday that his course is popular because the section people are "marvelous" and the subject matter is inherently interesting.

Fine Arts 13, "Introduction to the History of Art," ranked third on the list with 356 students, and Humanities 9b, "Oral and Popular Literature," was fourth with 350.

Math 1b, "Introduction to Calculus," Natural Sciences 111, "Computers in Society," and Chemistry 20b, "Organic Chemistry," were fifth, sixth, and seventh.

Andrew M. Gleason, Hollis Professor of Mathematics and Natural Philosophy and an instructor in Math 1b, said yesterday that Math 1b was popular because of the "central position of calculus with respect to other subjects."
