tude until there was complete stoppage of the respiratory 
movements. If the pulmonary insufflation was made without 
waiting too long, and it was kept for one or two minutes, 
spontaneous respiration returned, provided the pleura was 
kept closed. The simple occlusion of the pleura would have 
the same result if done after only four or five large respira¬ 
tory motions ; if later it is useless. 
In respect to the pulse, there was, first, a period of accel¬ 
eration corresponding to that of the respiration, and then fol¬ 
lowed a general diminution until a definitive arrest a little 
previous to that of the respiration. These disturbances, with 
the death which soon followed, were the results of the phe¬ 
nomena of arrest and asphyxia. 
After the section of the pneumogastrics, the retarded 
beating of the pulse became more readily perceptible; the ac- 
cel eration persisted with even greater rapidity ; then, some 
instants after complete cessation of the respiration, it ceased 
gradually by the diminution of the systoles. The influence 
of asphyxia was also manifest, the markings of intra-brachial 
pressure showing that the movements of the thoracic frame 
were entirely inefficacious upon the chest, open only on one 
side. How is it that the sound lung itself did not dilate ? 
The hypothesis of Weill must here be admitted, viz., that 
of a displacement en masse of the mediastinum ; the aspiration 
produced in the sound side by the movement of inspiration 
may be without effect upon the lung if it exhausts itself in 
displacing the mediastinum.— Comp. Rend. Soc. Biol. 
NOTES UPON THE COMPOUND ANTISEPTICS. 
By Drs. deChristmas and Respant. 
In all the researches made into the nature and operation 
of antiseptics, the curious phenomena is brought out that by 
the association of several antiseptic substances possessing 
similar properties a new body is produced with a microbicide 
power far exceeding in its peculiar properties that of either 
of the component substances used singly. 
It is upon this data that the authors have made methodi-
