Note 470 — ON THE PROGNOSTICS.

This graphic description of the movement of the hands in delirium is nearly original, being but slightly touched upon in the Coacæ Prænotiones, 76. The terms are copied by most of the ancient authors subsequent to Hippocrates, in their descriptions of phrenitis and febrile delirium. See in particular Paulus Ægineta, Book III., 6. Stephanus, in his Commentary, has several very philosophical remarks on this passage, namely, upon the rationale of the ocular deception which leads to these extraordinary movements of the hands. (Ed. Dietz, t. i., pp. 103, 104.)
