4 OBSERVATIONS. 



And those who are most acquainted with this 

 practice wonder least how dog-kenneljt 

 in every part of the kingdom, are so amply 

 furnished with horse-flesh. 



As an elucidation of this circumstance, and 

 to corroborate the consistency of these obser- 

 vations, we need only advert to the treatment 

 of the human species in the time of that lu- 

 minary, the famous Sydenham, who was so 

 much the celebrated favourite of his day, ~it 

 was almost supposed he could do no wrong. 

 It being then a common practice of his— to 

 order boldly THIRTY ounces of blood to 

 be taken from the arm of a man, without fear 

 of murder or danger of punishment . And this 

 is not altogether hkely to create wonder, 

 wdien we recollect there is no law existingf to 

 hang a physician for error in judgment. Time 

 and experience have fixed the standard, accord- 

 ing to cases, circumstances, and exigencies, 

 from SIX ounces to sixteen, which is nearly 

 one half the original evacuation ; so that we 

 find by this change of quantity the modern 

 human body is supposed to contain no more 

 than one half the proportion of blood that ran 

 in the veins of the heroes of antiquity.
