| Title | Unpublished paper, 'Accommodation of vision and the anatomy of the ciliary body and iris' by Arthur Trehern Norton |
| Creator | Norton; Arthur Trehern (1841-1912); British surgeon; anatomist |
| Date | 1873 |
| Description | Norton aims to show that the increase in the convexity of the lens, when accommodated for near vision, is caused by compression of the equator of the lens by an erectile cushion composed of the ciliary processes turgid with blood, the ciliary muscle being the motor agent; also that the iris aids accommodation by increasing its rapidity, but that accommodation of vision can be effected slowly without the assistance of the iris. Norton states that by dissection of human eyes he has determined the existence of an erectile mass attached to the interior surface of the ciliary muscle from which the ciliary processes proceed, and that in dissections of injected specimens the vessels of the ciliary processes and of the erectile mass can be seen to pass through and between the fibres of the ciliary muscle near to the apex of that muscle.
Marked on front as 'Archives Oct 1873'. Note on front reads 'The anatomy is in print but has not been published'. Includes four pages of printed material on the ciliary body and two plates showing the ciliary muscle and the eyeball respectively.
