Note 1253 — LETTER XXXIV.
Reading edition
I was not aware that Knoch had observed this part, till some time after the publication of my paper On Mr. William MacLeay's Doctrine of Affinity and Analogy (see Linn. Trans. xiv. 105—), when I happened to meet with it in a letter from a friend, received more than thirteen years ago; but without any reference to the work of Knoch, in which it was stated. It was doubtless taken from his Beiträge zur Insektengeschichte.
