Rh “While this process was devised by me with reference to the preparation of paper for use by photographers, I do not by any means consider it as limited to such use, as sheets of material may be coated in the manner described with alcohol, aqueous, alkaline, or acid solutions, or with fused resins, oils, varnishes, or paints But care must be taken to have the fluid, with which the sheet is saturated, one with which the covering or coating solution or fluid has an affinity.

“The object of thoroughly and uniformly saturating the sheets before applying them to the table is to cause them to lie flat thereupon, so that, if the sheet is of uniform thickness, there will be no valleys in which the deposit of coating matter will be thick, or hills on which it will be thin.”

It will be seen that the patent issued to Mr. Crosman is only for making tissue for use by the Swan, or other processes described hereafter. What arrangements, if any, will be made to allow the photographers of this country to use Mr. Swan's process we cannot yet say, but we are assured that no interference whatever will at present be made with any one who may feel inclined to take it up and experiment with it. A great many have already done so, and are also making their own tissue. The making of the tissue is troublesome, and it is more economical to buy it of the dealers. Great credit, honor and praise is due to Mr. Swan for his process, and the whole world is indebted to him. We had heard that Mr. Swan's and the Crosman interest had been combined, but there has been no public announcement of such a combination. We suppose it is not Mr. Swan's intention to disturb those who are working his process in this country at present. In time, he will no doubt announce his plan for licensing.

A number are now using the process, and have been doing so for two years without interference, and we believe all are safe in doing the same.
