I saw again the apparatus for using high oxygen with children, 
that is, the bell jar with the rubber blanket attached to it made 
of fabric used for balloons, and Mile. Bochet was much interested 
in haying found a new type of zipper that seemed to produce an 
air-tight closure. Oxygen was introduced at 5 liters per minute, so 
she thought she was getting 60 per cent oxygen and says it works 
very well. As near as I could make out they were not using the infant 
respiration chamber that we sent them, although they were making 
attempts to put it in condition. The trouble was to get a blower that 
was air tight. The closed circuit is out of the question and for the 
open circuit I don't think they have sufficiently mastered the technique 
of the Plantefol apparatus to justify its use for such a small carbon- 
dioxide increment, and worse than that I don* t believe that the 
Plantefol apparatus at its best and with the best operator approximates 
the accuracy of the Carpenter apparatus. So the outlook is not 
particularly good as it appears to me. 
Mile. Bochet is certainly a very clever girl, but I don't know 
how far she is getting. I think if she could have a year with us 
she would be quite a different person but that is out of the question.
