428 THE LAWS OF ORGANIC 



ment, at 98^, and at another at 99, the sensibi- 

 lity of the instrument appeared proportionately 

 augmented. The gentleman, to whose animal 

 temperature I allude, is young, vigorous, and ap- 

 parently of strong constitution ; his chest is very 

 well developed, and he has not been subject to 

 any pulmonic disease whatever ; yet, notwith- 

 standing these organic adaptations for the gene- 

 ration of animal heat, and for the force and ful-

 neath the average, and it is with the greatest dif- 

 ficulty that he can bear cold. His pulse ranges 

 from 60 to 65 in a minute, and is at all times small. 



DXXIII. Having, by the preceding experi- 

 ments, observed the operation of emetics upon 

 the system, in reference to certain preconceived, 

 and, I almost venture to say, established princi- 

 ples, I hope the attempt will not be deemed pre- 

 sumptuous that aspires to regulate in future the 

 exhibition of emetics, by explaining, in a clear

DXXIV. Emetics may be divided into two 

 kinds ; into those which nauseate, and into those 

 which excite vomiting. The former have always 

 been considered as depressing the circulation,
