Professor of Botany in the University of Edinburgh (1845-1879)

to the University where he graduated D.Sc. in the Department 
of Physical and Natural Science and also matriculated in the 
Faculty of Medicine. 
In 1874, when he was only 21 and an undergraduate in the 
latter Faculty, he was selected to accompany the party which 
went out to Rodriguez to observe the transit of Venus and at 
this early age he showed full promise of his powers. One of his 
letters from Rodriguez was considered of such interest by Sir
