[The defects described by our correspondent are so frequent with manipulators in the wax-paper process, and which DR. MANSELL has called so aptly a "gravelly appearance," that we shall be glad to receive communications from those of our numerous correspondents who are so fortunate as to avoid it.] _The New Waxed-paper, or Ceroleine Process._--The following process, communicated to the French paper _Cosmos_ by M. Stephane Geoffroy, and copied into _La Lumiere,_ appears to possess many of the advantages of the wax-paper, while it gets rid of those blemishes of which so many complain. I have therefore thought it deserving the attention of English photographers, and so send a translation of it to '"N. & Q." As I have preserved the French measures--the _litre_ and the _gramme_--I may remind those who think proper to repeat M. Geoffroy's experiments, that the former is equal to about 2 pints and 2 ounces of our measure; and that the _gramme_ is equal to 15.438 grains, nearly 15-1/2. ANON. I send you a complete description of a method for either wet or dry paper, which has many advantages over that of Mr. Le Gray. I assure you it is excellent; and its results are always produced in a manner so easy, so simple, and so certain, that I think I am doing great service to photographers in publishing it. 1st. I introduce 500 grammes of yellow or white wax into 1 litre of spirits of wine, of the strength usually sold, in a glass retort. I boil the alcohol till the wax is completely dissolved (first taking care to place at the end of my retort an apparatus, by means of which I can collect all the produce of the distillation). I pour into a measure the mixture which remains in the retort while liquid; while it is getting cool, the myricine and the cerine harden or solidify, and the ceroleine remains alone in solution in the alcohol. I separate this liquid by straining it through fine linen; and by a last operation, I filter it through a paper in a glass funnel, after having mixed with it the alcohol resulting the distillation. I keep in reserve this liquor in a stopper-bottle, and make use of it as I want it, after having mixed it in the following manner. 2nd. Next I dissolve, in 150 grammes of alcohol, of 36 degrees of strength, 20 grammes of iodide of ammonium (or, of potassium), 1 gramme of bromide of ammonium or potassium, 1 gramme of fluoride of potassium or ammonium. I then pour, drop by drop, upon about 1 gramme of fresh-made iodide of silver a concentrated solution of cyanide of potassium, only just sufficient to dissolve it. I add this dissolved iodide of silver to the preceding mixture, and shake it up: there remains, as a sediment at the bottom of the bottle, a considerable thickness of all the above salts, which serve to saturate the alcohol by which I replace successively the saturated which I have extracted by degrees in the proportions below.
