the temperature was found Lo vary a feiv degrees from day to day, hut the lowest tempera lure was consistently '22.2 ± 2.2"K. By realistically assuming that, all sources wore then contributing their fair share (as is also tacitly assumed in Table II) it is possible to improve the over-all accuracy. The actual system temperature must be in the overlap region of the measured results and the total results of Table JI, namely between. 20 and 2J.9°K. The most likely minimum system temperature was therefore r»,.lem - 21 ± i°k.*

The inference from this result is that the " + " temperature possibilities of Table II must predominate.
