and sulpliuret of lead is formed. The same simple experiment 

 will demonstrate that sulphur exists in the bile and in urine also. 

 The sulphur probably exists in the above substances in the state 

 of sulphuretted hydrogen, if this gas be not formed by the heat, 

 or rather by putrefaction. It is also probable that sulphur exists 

 in all the animal humours: but I have not found it in cow's milk; 

 at least I did not discover its presence by operating on a few 

 quarts of this fluid." 



MESSRS. GALL AND SPURZHEIM's SYSTEM OF CRANIOLOGY. 



Having noticed in a former number of the Philosophical 

 Magazine the Lectures of Doctor Spurzheim on the Physiology 

 of the Brain, it may be interesting to many of our readers to 

 have a short account of his proceedings in that science. The 

 Lectures, which commenced on Monday the llth instant, began 

 with a declaration of the general plan of the system, and a 

 refutation of the several opinions of other philosophers respecting 

 the nature of the mind. He then proceeded to give an account of 

 the different organs of the brain, and the means of discovering 

 the relative degree of their development severally in different 

 individuals. In order to give the reader some idea of the general 

 outlines of the system, I must observe that the brain has always 

 been considered as the organ of thought ; that the present system 

 differs from the general notion of physiologists, in regarding the 

 brain not <is one organ, but as an assemblage of different organs 

 which have different functions ; and demonstrates that the mind 

 varies according to the relative degree of strength of these dif- 

 ferent organs in different people. These organs (which are 

 upwards of thirty in number) are the material conditions of 

 distinct faculties. The faculties are divided into, first, those 

 which belong to the intellect, or what tlie Germans call Gh'eist; 

 and secondly, those of the sentiment and propensities, which they 

 call Gemul/i : these latter are again divided into, first, sentiment, 

 and secondly, propensities. We have not room to enter further into 

 the detail of this system. We shall therefore ejid by observing, 

 that however unwilling the public may be to adopt any new 

 system at first, and however intimidated by the numerous im- 

 positions of pretenders to science ; every philosophic mind who 

 will attentively study the present system will (we are assured by 

 those who have studied it) be amply repaid for his trouble — even 

 should he remain unconvinced of its truth. We hope to give 

 more detail in our next. Dr. Spurzheim has a very respectable 

 class, and is attended by many of the most eminent and ingenious 

 medical practitioners of tlie metropolis.
