the Thorax^ for they preffcd agaiiift the inward 
Orifice of the Wound, and continued in this 
State for fome time : But then as this right 
Lobe of the Lungs fell gradually more and 
more, fo the Dog fliewed more and more 
Uneafinefs in breathing ; and on dilating or 
contrading the Thorax by the Adlion of the 
Diaphragm, the Air ruflied briskly in and out 
at the Incifion : But when the Orifice was 
covered by drawing the Skin over it, the Dog 
immediately breathed in a natural cafy manner. 
2. Hence we may obferve, that the Lungs 
Continuance in a dilated State, for fome time 
after the Orifice was made, muft be owing to 
the Force of the Blood in the pulmonary Ar-
