560 APPENDIX, 



" Some experiments on the proportion of carbonic acid exhaled in 

 phthisis pulmonalis." Fifteen patients, nine males and six 

 females, in decided consumption, were operated on thirty-two 

 times. The disease had reached the stage of softening in all but 

 one, and in three there were cavities ; the pulse averaged 104, the 

 respiration 30. The result of the experiments in these cases was 

 this : the percentage of carbonic acid averaged 4*467 5 the extremes 

 being 3*7 and 5'5. The result of experiments similarly made 

 upon twelve healthy individuals, six males and six females, at an 

 average age of 29, showed an average percentage of 4*6916, 

 ranging from 4*2 to 5 '9. G. E. D.]
