These notes (not transcribed by Finberg) continue on folio 28 verso (D06775); for convenience they are given in full here:
Carlisle affirms the mind is only | a quick perception and that some having | a quicker degree of perception is Genius | or rather only the common powers of mental | faculties which if carried by enthusiasm | is capable of producing that which it | thinks itself able to obtain and therefore | what has been done by the ancients may | be done again.

For Turner’s notes for his lectures as Professor of Perspective at the Royal Academy see Introduction to this sketchbook and under folio 15 (D06749). This additional text is probably connected with his plans for Lecture 1, on perspective and geometry, in which he sought to establish the relationship between his subject and the others taught by the Academy’s Professors, including anatomy and sculpture.1 It also seems to anticipate his discussion of the subject of vision, developed in his later courses of lectures from 1814 to 1818.
