Excerpt from The London and Edinburgh Philosophical Magazine and Journal of Science, Vol. 1: New and United Series of the Philosophical Magazine and Journal of Science; July December, 1832 1. On the Refraction of the differently-coloured Rays in Crystals with one and two Axes of Double Refraction. By M. Rudberg. As the remarkable discovery of Fraunhofer of the dark rays in the spectrum gives an unexpected degree of precision to researches on the refraction of coloured light, it becomes interesting to determine by this accurate method the indices of refraction. But for doubly refracting crystals similar researches are entirely wanting, which might show in general how the double refraction varies with different colours, and how this variation produces the different inclination of the optic axes which Mr. Herschel has observed for the differently-coloured rays in crystals with two axes. Besides, an inquiry into the double refraction of coloured light would add to the small number of accurate determinations of dispersion which we owe to Fraunhofer.

Excerpt from The London, Edinburgh, and Dublin Philosophical Magazine and Journal of Science, Vol. 1: January-June, 1851 The commencement of this New Series suggests the hope that the Philosophical Magazine may at this period receive an accession to the number of its supporters. Those of its Editors who have stood beside it for half a century, and made it their endeavour that it should be honestly, independently and usefully conducted, may be permitted, on this occasion, to urge how much the means of giving additional interest and value to the Journal must depend upon the support afforded to them; in the hope that many lovers of science who are not already subscribers may take this opportunity of adding to the number of those by whose encouragement alone the work has been upheld.

Excerpt from The London, Edinburgh, and Dublin Philosophical Magazine and Journal of Science, Vol. 19: January-June, 1860 The instrument consists of a glass tube, ab, in serted in a light half-pint flask A, the connexion at e 1) being made air-tight a thermometrical scale m n attached to the tube 3 a moveable barometrical scale C D Q a piece of very thin india-rubber tied over the top of the tube A B, to keep the external air from coming in contact with the strong sulphuric acid occupying a portion of the tube and flask. The tube AB is about 24 inches long, and about gths of an inch internal diameter; it is secured to the flask in the following manner z - Two perforated corks, e and fitting the neck of the flask, are placed on the tube the lower one, e, is coated with a solution of india-rubber to render it impervious to air; the upper cork, being raised a little, the cork e with the tube is pressed down to its proper depth some pieces of chemical cement, fusible at a gentle heat, are now placed above the cork e, and a gentle heat is applied until the cement melts the upper cork v is then brought down to its place upon the melted cement when the cement has cooled, the tube will be found firmly fixed in the flask and perfectly air-tight. Strong sulphuric acid of commerce is introduced through the tube by means of a pipette, the tube being held in an inclined position. N.b. All this process of cementing may be obviated by having a globe and tube bent in the manner shown in the succeeding diagram but I preferred showing how the instrument may be constructed cheaply, and with materials which may be readily obtained.
