We learn with much regret that on the 12th of February the printing establishment of the Abbé Migne, at Mont Rouge, in the southern suburb of Paris, was totally destroyed by fire. No particulars of the occurrence have yet been given. The enterprise, conducted with extraordinary vigor and ability by the abbé, was unique in the history of publishing. It was founded for the purpose of supplying books for the Catholic clergy of France and the whole world. Nearly two thousand volumes, in large imperial octavo, comprising the whole of the Greek and Latin fathers of the church, and writers on theology and ecclesiastical history, were edited, published, and kept constantly in print, employing a staff of several hundred persons, including literary men, printers, binders, etc.--_London Publishers' Circular._ ---- _Amaurosis from Tobacco-Smoking._--Mr. Hutchinson has reported thirty-seven cases of amaurosis, of which he says thirty-one were among tobacco-smokers. Mr. Hutchinson concludes: 1. Amongst men, this peculiar form of amaurosis (primary white atrophy of the optic nerve) is rarely met, except among smokers. 2. Most of its subjects have been heavy smokers--half an ounce to an ounce a day. 3. It is not associated with any other + affection of the nervous system. 4. Amongst the measures of treatment, the prohibition of tobacco ranks first in importance. 5. The circumstantial evidence tending to connect the affection with the habit of tobacco-smoking is sufficient to warrant further inquiry into the matter on the part of the profession.--_Popular Science Review._ ---- _The New Laboratory at the Sorbonne._--This magnificent establishment, which is to be devoted to the pursuit of chemical investigation, seems to provide for the student's wants on even a more liberal scale than its celebrated rival at Berlin. Besides the various rooms for researches in chemistry, _pur et simple_, there are numberless apartments exclusively intended for investigation in optics, electricity, mechanics, and so forth. Motive-power is provided for by a steam-engine of great force, which is connected by means of bands with wheels in the several laboratories. Again, besides the ordinary pipes carrying coal-gas, there will be a series of pipes supplying oxygen from retorts kept constantly at work. Indeed, altogether the new laboratory will be a species of Elysium for the chemical investigator. ----
