JOHN STUART MILL AND BOTANICAL STUDY. 



By E. J. Hii,L. 



IN the Autobiography of Mill is an account of the way he became 

 interested iu botanj^ and of its advantages to him in literary work. 

 His father, James Mill, was a friend of Jeremy Bentham, the well- 

 known publicist and advocate of the utilitarian philosophy. This led 

 to an acquaintance with General Sir Samuel Bentham, a brother of 

 Jeremy and father of George Bentham, the botanist. Sir Samuel had 

 an estate in the south of France, to which young Mill was invited for a 

 visit of six months in 1820. By the kindness of the family it was pro- 

 longed to nearly a year. Under the influence of George, his senior by 

 six years. Mill then being fourteen, he took up the study of botany. He 

 also attended a course of lectures on zoology' and chemistry at the 

 neighboring College of Montpellier, which doubtless bore fruit of a 

 similar character, though his taste in after j^ears seems to have been 

 chiefly confined to botany.
