My dear Sir,

I am very sorry to be obliged to trouble you about a few sheets. In going on with the translation of your new book I came to a stoppage, as p. 145–208 are wanting.¹ I am not quite sure, if I have got them shortly before or after my short absence from Leipzig in the end of September, or if I have not received them at all. They may be mislaid amongst the heaps of new litterature pouring in for the new Jahresbericht.² So I beg your pardon very heartily, but ask you to have sent these four sheets once again. I received the conclusion with the Index this morning.

I am delighted with the book, as it tells again a most wonderful lesson of methods of observation, patience and thought. The first Chapter will perhaps seem a little long to general readers, but I think it is one which ought to be read most carefully.

With my best wishes for your health (I am almost stiff with a severe rheumatism in my right shoulder) believe me | My dear Sir, | Ever yours sincerely, | J. Victor Carus
