INFLAMMATIONS. 



thetic fever. As these fhree forms are liable to be easily mis- 

 taken for each other, I shall place the symptoms of each in juxta- 

 position in the following Table : 



COMPARATIVE TABLE OF SYMPTOMS. 



Acute Pleurisy. 



Early 

 symp- 

 toms. 



Stetho- 



scopic 



sounds. 



Percus- 

 sion. 



Termin- 

 ation. 



Shivering, with 

 slight spasms of the 

 muscles of the chest ; 

 inspiration short and 

 unequal in its depth, 

 expiration full, air 

 expired not hotter 

 than usual ; cough 

 slight and dry ; pulse 

 quick, small, and 

 wiry. 



No very readily dis- 

 tinguishable sound. 

 A practised ear dis- 

 covers a friction 

 sound or rubbing. 



Produces at first no 

 result different from 

 a state of health. 

 After a time, when 

 serum is thrown out, 

 there is increased 

 dullness. 



The symptoms ei- 

 ther gradually dis- 

 appear, or lymph is 

 thrown out, or there 

 is an effusion of se- 

 rum or matter, with 



Acute Pneumonia. 



Acute Bronchitis. 



Strong shivering, 

 but no spasms ; in- 

 spiration tolera- 

 bly full, expiration 

 short, air expired 

 perceptibly hotter 

 than natural ; nos- 

 trils red inside ; 

 cough violent and 

 sonorous, with ex- 

 pectoration of rusty 

 coloured mucus ; 

 pulse quick, full, 

 and soft. 



A crackling sound, 

 audible in the early 

 stage, followed by 

 crepitating wheez- 

 ing. 



Dullness after the 

 early stage is pro- 

 duced by the thick- 

 ening of the ti.ssue, 

 approaching to the 

 substance of liver, 

 hence called " hepa- 

 tisation." 



If the symptoms do 

 not disappear, there 

 is a solidification of 

 the lung, by which 

 it is rendered imper- 

 vious to air, and in 



Shivering, soon fol- 

 lowed by continual 

 hard cough; inspir- 

 ation and expira- 

 tion equally full ; 

 air expired warm, 

 but not so hot as in 

 pneumonia ; cough 

 soon becomes moist, 

 the mucus expecto- 

 rated being frothy, 

 scanty at first, but 

 afterwards profuse ; 

 pulse full and hard. 



The sound in this 

 form varies from 

 that of soap bub- 

 bles to a hissing or 

 wheezing sound. 



No change. 



The inflammation 

 generally subsides 

 by a discharge of 

 mucus, which re- 

 lieves the inflamma- 

 tion ; or it may go
