| Title | Unpublished paper, 'The description of an organ by which the eyes of birds are accommodated to the different distances of objects' by Philip Crampton |
| Date | 7 June 1811 |
| Description | Crampton discusses the ciliary muscles in the eyes of ostriches and eagles, positing that these muscles flatten the cornea, reducing its convex shape and allowing the birds to view objects at a distance.
Numerous corrections and marginalia appear throughout in ink and graphite. The title originally began with 'On the means', but this has been struck out.
Subject: Zoology
Written by Crampton in Dublin [Ireland]. Communicated by H [Humphry] Davy. Read to the Royal Society on 16 January 1812.
