An upright bath (Fig. 1) is the more convenient form for use in the ferrotype process of photography. This bath is not very easy to make, and can be purchased very cheaply. A flat porcelain dish may he used as a hath, but must be kept well covered as it offers a large surface for the deposition of dust. For a dipper (Fig. 2), cut a piece of glass A and attach with good cement a strip at B. The plate then rests on B face up and may be lowered gently into the hath.
