Trusting more to your friendship for me and to my memoranda, which
always guide me in my lectures, than to the notes taken by the students,
I send you herewith the entire fifth lecture, together with to-day’s
recapitulation. I am sure, you will not find anything anti-philosophical
therein. You may make whatever use you like of them—except a copy for
publication—please send them back before Saturday. That the memoranda
were made for my own use only, you will observe by the confusion in
their composition—the desire, however, to be always frank, makes me
forget any consideration which vanity could suggest.[3]
