ortant cases the radiographer should develop the platehimself. In hospital practice this is not possible, but there one generallyhas a nurse or photographer who looks after the development. In any caseit is of importance that the person who develops the plate should have someknowledge of the conditions under which the radiograph has been taken.The developer is usually one containing metol and hydroquinone, thoughin some cases pyro-soda may be employed. In a properly exposed plate, thedevelopment is generally completed in about five to ten minutes. The plate is fixed in the ordinary way. It should be allowed to fix outin the dark or in a ruby light, though the negative is frequently examinedby electric light before it is thoroughly fixed. We have not seen any harmful results from this premature examination,but nothing is to be gained by a hasty examination, and it is evident thatharm jnay result, so a good rule is never to examine a plate until it has beenallowed to fix out thoroughly.
