Five persons sat for 80 minutes in the room. In all cases 
there was great irregularity of breathing. They were all 
conversing with each other, which occupation, as was found, 
somewhat modified the effect. In two cases the rise of the 
pulse was considerable, viz., from 60 to 79, and from 84 to 91 ; 
but the numbers soon fell down to the natural amount, and 
would apparently have fallen much lower if one of the two 
persons had not felt too unwell to remain. The pulses in all 
cases were difficult to count, being excessively feeble, and the 
most delicate of the fingers was sought for the operation. 
No deficiency of strength was found in any of the trials, and 
the amount of carbonic acid rose equally from first to last. 
As the pulse fell and rose according to the individuality, the
