as the speediest means of subduing the fever and lowering the 

 circulation. Tartar emetic and digitalis are known also to have 

 the effect of retarding the circulation and lowering the pulse. It 

 will be observed that I apply these necessarily in the very early 

 stages ; spirits of nitre and flour of sulphur, which are continued 

 much longer, stimulate the secretions, and thus tend to purify 

 the blood and the system. My observations lead me to think 

 that the organs of respiration are on the first appearances, com- 

 paratively speaking, but slightly injured. It is not until after 

 a lapse of time that with the ear we can perceive that dul- 

 ness of sound which betokens injury. In the two Avhich died we 

 could distinctly trace the increase of this, until the flow of air 

 on the one side seemed entirely to have ceased, whilst on the 

 other we could plainly hear the air passing to and fro. On a 

 ■post mortem examination we found the lung on one side com- 

 pletely damaged, whilst on the other it was but little affected. 

 Whilst the greater heat of blood and the more frequent respira- 

 tion denote an excessive demand on the carbon, yet at the same 

 time the animal is devoid of appetite ; the necessary consequence 

 is a consumption of the components of the system. Tlie fats 

 will first be laid hold of, then, though probably not altogether 

 singly and separately, the carbonaceous components of the fibrine, 

 but as these materials are in succession less easily available, their 

 consumption seems necessarily to imply a greater exertion of the 

 organs of respiration. 



These considerations have led me to resort to a supply of food 

 rich in elements of heat, carbon, and hydrogen, in a form easily 

 available for respiration. Indian meal is particularly rich in 

 starch ; by the process of boiling it approximates more nearly to 

 sugar ; together with this I give sugar and treacle in appreciable 

 quantities, and also oleine oil. These ingredients are mixed and 

 given in warm water. Starch, sugar, gum, dextrin, &c., are 

 accounted the main supporters of the heat of animals when in 

 health ; they contain with carbon and hydrogen a considerable 

 proportion of oxygen. On this account they require less of the 

 oxygen of the air to effect their combustion. Their components 

 are : — 



The composition of oils differs very considerably from that of 

 starch and sugar, oils being much richer in carbon and hy- 

 drogen with less of oxygen. They contain on an average of 

 analysis : — 



Carbon. Hydrogen. Oxygen.
