Lungs for All

Hopeful of averting such underwater disasters as the S-51 and 54, the Navy Department last week placed orders for the manufacture of 6,300 of the new, successfully tested "lungs" developed jointly by Lieut. C. B. Momsen, Chief Gunner C. L. Tibbals and Frank Hobson, civilian engineer, to help sailors escape from sunken submarines (TIME, Feb. 18). Each of the 2,600 officers and men on submarine duty will be furnished with two or more of the devices.
