Apparatus for restoring the Action of the Lungs. 375 
stored by the return of the natural movements of the lungs aud 
diaphragm ; and then the plugs being removed from the nostrils, 
the mechanism of the apparatus is simply confined 10 aiD- the ° 
incipient play of the lungs. Thus an inlet for pure air is in- 
stantly provided, when it is wanted,—and lefore this period 
there is no necessity whatever for new air. 
I think your correspondent should have weighed these cir- 
cumstances before he endeavoured to detract from the merits of 
the invention; and he should moreover have made himself ac- 
quainted with the structure of the instrument in its last and im- 
proved form. 
As tu the application of the instrument to the purposes of & 
«« gas blowpipe,” and the exhibition of ‘* nitrous oxide ;” I car 
have no ambition to claim an interest in such an association. 
The transition from the resuscitation of human beings, to @ 
‘¢gas blowpipe,’’ &c, is so entirely ludicrous, that ] am asto- 
nished such an erratic fancy should be indulged in, 
Ihave little to add to my former observations. 1 continue 
to receive complimentary testimonials of the value of ny inven- 
tion; and it is cheering to add, that the apparatus, from its ac- 
knowledged utility, and superiority over the ‘ bellows’’ recom- 
mended by the Royal Humane Society, is about to be introduced 
into several infirmaries, &c. 
It is singular, that all with whom I have conversed, unite in 
condemning the common apparatus as inefficient, to use the 
mildest term. [have not found oze its advocate. It stands a 
rude and barbarous machine ; a disgrace to the scientific genius 
of our country. The subject of restoring suspended animation | 
has too long slept in inglorious repose ; aud it is one of the most 
important and commanding description. 
In soliciting the aid of Science to a topic pregnant with such 
interesting results, | can be biassed by by no sinister motive, be- 
cause Ihave no pecuniary interest to subserye. 1 desire, in re- 
turn for my bumbje tributary aid in the cause of humanity, ouly 
a fibre of that feeling which vibrates in the breast of him, who 
is conscious of having done that which philanthropy approves,— 
what good men only know, 
Surely the very numerous cases that have been unsuccessful, 
and where the appearances and circumstances were so flattering 
to the presages of hope, should have long ago convinced the 
Royal Humane Society of the inutility of the common means 
employed in resuscitation, and operated as a stimulus lor the 
exertions of intellect, to improve the plan, and eulist Science into 
the cause. 
When we see an obstinate adherence to the “ bellows,’’ not- 
withstanding its rudeness and imperfection, and even the et
