R Institution | 3 June 1845
Dear Sir
I have balanced until this minute whether I may or ought to accept your very kind invitation1; or whether I should deny myself the pleasure which it offers: & I am constrained at last to come unwillingly to the latter conclusion. I have almost finished my lectures2, I am also so tired (which with me always involves giddiness & other derangement of that kind) that I must take entire rest. I am sorry to say this but have no alternative[.]
