Lovell I'd like to make one comment· on the C&bin Inlet Valve, I
think a. future procedure woul d be to either open the visor
or unzip the hood prior to using the snorkel va.lve, so you
do not get this concentrated ambient flow into the suit in
a small concentrated area. Okay. Primary o2 System

Borme.n Prima:ry o System Monitoring was no problem. The cryogen

a.bout the 8th d~ it started venting. Performance of the
cryogenics bottles have been outstanding. The first one,
ECS o2 , started venting tod~. And we were still adding
heat to the other two bottl es. Let's see, this was Sunday
morning so that woul d have been the 8th day that i t started
ventmg. The quantity measuring system worked fine. The
flow rates were adequ&te . I just ca;nnot emphasize enough
the desirabil ity of going without suits. The pressure a.nd
temperature remained just nominal. We had dome plots &boa.rd
the spacecraft, and we checked them out. We had to use the
auto heater on the ~S o2 bottle perhaps, the first two days
or so and then we were able to turn the heater off complete-
