These are but a few examples or slight indications of the work he has actually done for us all. It is unnecessary to mention the incidental salutary influences of his visits to Canada and to India, which have left an abiding favorable impression of English royalty in those provinces of the empire. Nor can it be requisite to observe the manner in which the prince's country estate and mansion at Sandringham, with his care of agricultural improvement, of stock breeding, studs, and other rural concerns, has set an example to landowners, the value of which is already felt. We refrain upon this occasion from speaking of the Princess of Wales, or of the sons and daughters, whose lives, we trust, will be always good and happy. It is on the personal merits and services of the head of their illustrious house, with reference only to public interests, that we have thought it needful to dwell, in view of the fiftieth birthday of his Royal Highness; and very heartily to wish him, in homely English phrase, "Many happy returns of the day!"--_Illustrated London News._ * * * * * DEVELOPMENT WITH SUCRATE OF LIME. I have experimented with carbonate of lithia as an accelerator, and I have obtained with it rather favorable results. However, in opposition to Mr. Wickers, I have always found that carbonate of lithia, used even in larger doses than those recommended by this author, was not sufficiently active, and that development had to be too much prolonged in order to obtain prints of good intensity. I have also observed that the prints developed by this process were as often fogged as when I made use of carbonate of potash. The oxides of alkaline metals or their alkaline salts are not the only accelerators susceptible of being used in pyro development. Two oxides of the earthy alkaline metals, lime and hydrate of barytes, may also be used as accelerators. I will not insist upon the second, which, although giving some results, should be rejected from photographic practice on account of its caustic properties, and of its too great affinity for the carbonic acids in the air, which prevents the keeping of its solutions. This objection does not obtain for the first, provided, however, that ordinary lime water is not used, but a solution of succharate or sucrate of lime. In my experiments I have made use of the following solutions: _Solution A._ Pyrogallic acid. 10 grms. Sulphite of soda. 20 " Citric acid. 2 " Water. 120 " _Solution B._ Water. 1000 " Sugar. sufficient quantity to triturate. To which add a sufficient quantity of pure lime to saturate the sugar solution. In this manner we get a highly concentrated liquid, very alkaline, and which keeps for a considerable time. To develop, I mix:
