Description | Dr Joly FRS is intending to show at the Soirée examples of natural colour photography. Joly will use the lantern and also the microscopic projection apparatus and they will be glad if the Messrs will arrange to attach this for Joly's use. Joly will also use the ordinary projector. As the Society are not using the lantern just now it is quite open to the Messrs to make the adjustements when they choose. |
