Text on pp. 385-386 includes:
“The idea originated in suggestions from T. T. Paterson, who had been with me in 1934 and considered that the Melville Bay weather which we had experienced that year was particularly suitable for high altitude balloon flights such as were desired by cosmic ray investigators near the North Magnetic Pole. E. G. Dymond and H. Carmichael became interested, and in October 1936 began constructing light-weight apparatus for measuring cosmic rays at the greatest possible heights. Their investigations had to be made at high altitudes as the rays are strongly absorbed in the lower levels of the atmosphere. The proposed method was to have the apparatus lifted by two freely floating balloons, each 8 feet in diameter, which would reach a height of 15-20 miles before bursting, and as soon as one or the other burst, the second, acting somewhat like a parachute, would then bring the attached instruments gently back to sea-level. ”.
