Drawn from the register, in the manner of the Field Book, and opened beside the plates that explain each part of it.

FB-ENG-001, Fig. AAtmosphere in sectionThe whole standard atmosphere this station stands in, from the ground to the edge of space.
FB-ENG-003, Fig. CHydrostatic balanceWhy a barometer 134 ft up reads less: it weighs only the air above it.
On Oct 11 the noon sun stands 64 degrees above the horizon at 18.39 N, and the day is 11 h 41 min long. Level ground there takes 90 per cent of the noon sunlight a surface facing the sun would.
