The reflector C was {193} kept up to the required position by the handle lever, upright post and bolts.

Reflector B was hinged at its upper end at the top of the window frame, the only motion being necessary was that which would reflect upon the sitter the incident rays from reflector C--the reflector B being kept at the required angle by the connecting lever m, etc.

Suitable back-grounds were placed behind the sitter.
[Illustration: Fig.

12 (amdg_12.gif)] The reflector B and C, had frequently to be renewed, the heat of the sun soon destroying their brilliance or power of reflecting, light, before renewing them, however, we resorted to the springing of them, by which means their power was increased for a period.
The camera or reflecting apparatus, invented by Mr.Wolcott, was, from the nature of the case, better adapted at that day to the taking of portraits from life, than any other instruments.

After carefully examining the camera described by Daguerre, and the time stated as necessary to produce action for an image, it became evident to the mind of Mr.Wolcott at once, that more light could be obtained (as the field of view required was not large) by employing a reflector of short focus and wide aperture, than from a lens arrangement, owing to spherical aberration and other causes.
