XL Further Experiments and Ohservations on the Action of 

 "Poisons on the animal System, By B. C. Brodie, Esq. F.R.S. 



Mr. Brodie, who has commenced his experimental career with 

 considerable lustre, and promises to throw new light on some of 

 the darkest parts of physiology, published two papers in the 

 Philosophical Transactions for 1811, with the objects of which 

 it is necessary the reader should be acquainted^ before he can 

 fully understand the present article. The first of these is enti- 

 tled, the Croonian Lecture on som.e Physiological Researches, 

 respecting the Influence of the Brain on the Action of the Heart, 

 and on tlie Generation of Animal Heat. In this paper Mr. Brodie 

 has shown, by a number of well-conducted experiments, 

 ] . That the influence of the brain is not directly necessary to 

 the action of the heart; for by means of artificial respiration the 

 action of the heart was continued for a considerable time after 

 the head was cut off. Indeed, many phenomena previously 

 known, such as the length of time that the hearts of some ani-
