RESIGNATION OF PROFESSOR BRANDE. 
April 3rd, 1852. 
On the 16th of March Mr. Brande communicated to the Managers 
his desire to retire from the Chair of Chemistry which he had 
held since May, 1813. This day he gave his final lecture, at the 
conclusion of which he addressed his audience in the following 
words : — 
‘In this course I have endeavoured to show the intimate rela- 
tions that subsist between abstract science and the useful arts — 
between the refinements of modern chemistry and the improved and 
extended condition of some of our leading manufactures ; — and, 
having brought it to a conclusion, I must take my leave. I may 
truly say that I unwillingly resign my professorship ; but the attacks 
of hoarseness to which I am subject have of late so much interfered 
with my duties here, and are so manifestly aggravated by any 
exertion of voice, as to render the measure one, if not of necessity, 
at least of prudence. 
“Tn the year 1812, when Sir Humphry Davy retired from office, 
I was desired by the Managers of this Institution to prepare a pro- 
bationary course of lectures, which I delivered at this table in 
1813, and was immediately after elected to the vacant chair; so 
that I have been officially attached to the Royal Institution for a 
period of forty years. During the greater part of that time, namely, 
from 1815 to 1848, I also delivered a series of lectures and de- 
monstrations on theoretical and practical chemistry in the Laboratory 
below. They were intended for all denominations of students, and 
were given thrice weekly, from October to May. They were the first 
lectures in London in which so extended a view of chemistry, and 
of its applications, including technical, mineralogical, geological, and 
medical chemistry, was attempted; and I look back upon them with 
much satisfaction, because I think I may fairly claim for them the 
merit of having completed the scheme, and added to the usefulness 
of this Institution ; of having helped to diffuse that knowledge and
