378 RESPIRATION 



last-named method, the determination has almost always been 

 limited to the relative amount of carbonic acid in the air, without 

 regard to the volume of the expirations, and hence we need 

 hardly observe that such experiments are scarcely of any value. 



My experiments on the process of inflammation and its influ- 

 ence on the perspiration have been unavoidably limited to rabbits, 

 in whom it is very difficult to excite an acute inflammation. I found 

 it was not sufficient merely to wound the animals, and that it was 

 necessary at the same time to inject stimulating substances into 

 the wounds ; but notwithstanding these measures, I always had to 

 make several fruitless attempts before any individual animal could 

 be brought into the condition necessary for these experiments. I 

 subjoin only the results of those experiments to which I attach 

 the greatest importance, and in which the morbid phenomena, as 

 well as the composition of the blood, indicated the presence of the 

 process of inflammation. 



In (a) and (b] the lungs were the seat of inflammation, and in 

 (c) and (d) the inflammatory process extended over several muscles. 



(a) In every three hours a rabbit excreted, at the mean tem- 

 perature, the following quantities of carbonic acid : 



Before the animal was wounded, and during three 



hours in the morning 3'820 grammes. 



Immediately after being wounded 3'877 



On the first day 2'951 



second day 3'217 ,, 



third day 2*308 



fourth day 1'838 



in the evening 1731 



(b) In every three hours a rabbit excreted, at the mean tem- 

 perature, the following quantities of carbonic acid: 



Two days before being wounded .... .... .... 3'170 grammes. 



Immediately after being wounded .... .... 3*392 



On the first day 3'199 



second day .... ... .... .... .... 2'914 



third day 1'877 



(c) In three hours a rabbit excreted, at the mean temperature, 

 the following quantities of carbonic acid : 



Two days before being wounded .... .... .... 3*592 grammes. 



Immediately after being wounded .... .... 3 % 947 



On the first day 3'533 



second day.... .... .... .... .... 2*711 ,, 



third day 2-179 



fourth day 2*098
