202 Literary and Philosophical Intelligence, 



In his lectures on milk, which are delivered in this 

 department of his course, the Professor does not confine 

 himself merely to the natural and chemical history of 

 this fluid as it is furnished to us by the female- of the 

 human kind, and by other animals ; nor to an inquiry 

 into the diseases or conditions of the system, in which 

 milk is supposed to be salubrious or injurious ; but he 

 is led into extensive excursions on the duration of the 

 term of suckling, and on the state of infancy, among na- 

 tions, particuUuly among the savage nations of America; 

 on the moral habits of mothers, so far as they may be 

 supposed to be connected with the practice of suckling 

 their own children ; and on other questions of this kind. 



This part of the lectures involves the consideration of 

 many subjects relative to the philosophy of agricul- 

 ture, and the PHYSIOLOGICO-NATURAL HISTORY OF 



MAN : such, besides some that have already been hinted 

 at, as the question relative to the food of plants; 

 the ROTATION OF CROPS ; the nature of soils ; the 



INFLUENCE OF LIGHT UPON VEGETABLES, AND UP- 

 ON animals ; SPECULATIONS CONCERNING THE 

 COLOUR OF THE HUMAN SPECIES, 5cC. 



B. MEDICINES. 



Having finished the subject of aliment, the Professor 

 proceeds to treat of medicines, more properly so called. 

 This part of the course is by far the most extensive, the 

 subject of aliment being discussed in about three weeks, 

 or in ten lectures.
