An expedition to Belgian Congo composed of seven men, conducted by Dr. Richard P. Strong, professor of Tropical Medicine, will sail from New York tomorrow to spend six months studying the control and elimination of onchocerciasis.

The expedition will pay especial attention to the Katanga region where Dr. Strong will continue the studies he has made in the Congo in 1926-27.

Beside their study of onchocerciasis, the expedition will gather material in the fields of botany, mammalogy, ornithology, herpetology, helminthology, and entomology. Accompanying Dr. Strong will be Dr. Joseph O. Sequaert, assistant professor of Entomology; Dr. Jack H. Sand-ground, assistant professor of Tropical Helminthology; Henry E. Mallinckrodt, laboratory assistant and photographer; R. Stuyvesant Pierrepont, Jr., zoological assistant; and Byron L. Bennett, technician.
