The whole page is taken up with the following notes:

The passage is part of a sequence of notes and diagrams which runs back from folio 79 verso (D07487) to folio 72 verso (D07473). The previous page of notes is folio 74 verso (D07477); the next and last is folio 72 verso (D07473). The semi-diagrammatic drawing of a boat on folio 81 verso (D07491) also appears to belong with these notes, concerned with sunlight or light in general in terms of reflections and the casting of light and shadow from polished objects or bodies of water. They relate to Turner’s fifth Royal Academy perspective lecture, on reflection and refraction.
Davies has registered most of the notes from folio 91 verso (D07511) to folio 72 verso as ‘on light and shadow’;1 those from folio 91 verso to folio 82 verso (D07493) are distinct, dealing with sunlight as parallel or divergent rays.
