  • of silica gel about 6' [feet] tall + 10" [inches] in diam [diameter] (contains the gel in removable serum cannisters) then through a cannister of (KOH?) [potassium hydroxide] + then another Silica gel [therefore symbol] air flow is monitored by a ball type flowmeter. O2 [oxygen] is bled into the system as follows. O2 [oxygen] comes from cylinders into a water bath type of spirometer that keeps the pressure constant. This is kept operating by a water tube gadget that activates switches when empty + when full thus starting + stopping the filling procedure. O [oxygen] is metered on a circular dial flowmeter. There are gadgets on the side of the chamber to permit the adjustment of internal pressure. Temp. [temperature] control is handled by a best exchanger system consisting of panels of coild [coiled] [illegible word crossed out] copper pipes between what looks like magnesium or anodized aluminum sandwiches. These are controlled in 3 batteries, Head, middle + tail. They are fron [word crossed out] loaded [word crossed out] or brine loaded + operate from a refrigerator bath in which coils are immersed in a brine bath that is either heater with immersion heaters or cooled by standard refrigeration. Motors or moving parts then are refrigerator, oxygen pressure equalizer, air pumps. A battery of leads passes into the unit for attaching 12 separate thermistors. He has done some very interesting work on the reactions of sheep to changes in temperature etc. It is in press just now but I saw his graphs. They are just what we are driving at. He finds that the greater part of the water loss even of non sweating animals is through the skin. He has found that the living skin constantly changes its heat conductivity contrary to the finding of Irvine et al on dead skin Small thermocouplers in the ears have revealed them as important heat losing organs
