Using the Ilfordplates and the formula given above he said he hadto develop until the high lights were well seen onthe back of the plate.

If this is followed out, the more experi-ence one gets the more will he find that one makeis perhaps as good as another, and capable of pro-ducing good negatives if the exposure and devel-opment are correct. The Ilford formula is the one used by the lec-turer, and he said had served him well for someyears. It consists of four grains to the ounce of In developing it is well to keep as far awayfrom the light as possible, for no dark-room lampseems to be absolutely safe. We can do with per-fect impunity at four feet what would be quitefatal at one foot. The lecturer used two sheetsof canary fabric, and was able to read the paperwhilst development w^as going on.
