Very strict studies in anatomy were not much in vogue among the early painters. Our author recommends drawing from nature, and lays down his canon of proportions of the human body, which will be little heeded by our academies. The old Italian is not very complimentary to the sex. Mr Etty will open his eyes with alarm, to find he has been practising all his life in a wrong direction, when he reads "leave that of woman, for there are none perfectly proportioned." We are not quite certain, if some of Mr Etty's stay-spoiled figures are taken for examples, but that the opinion of the old Italian may be in some credit. We spoke in the commencement of this paper, of the "Gummi Fornis," which M. Merimee concluded to be copal. The translator, in a note, offers a conjecture, not without its probability, that it may have been sandarac, the "Vernice da Scrivere" of Cennino, and quotes Raffaello Borghini in his "Reposo." If you would have your varnish brilliant, use much sandarac--it makes certainly a very hard varnish--it is difficult to combine it with oil. We suppose it to have been one of the condemned novelties as a vehicle for painting, from its being included in the condemned list of trash, as only fit to polish boots, that moved the satirical pen of Boschini:-- "O de che strazze se fa cavedal! D'ogio d'avezzo, mastice e sandraca, E trementina (per no dir triaca) Robe che ilusterave ogni stival." MARCO BOSCHINI. Much has been said of late of "Encaustic Painting." It must have been discontinued before the time of Giotto, as shown by the experiments of Lanzi--no wax has been found in pictures painted after the year 1360. We know that Sir Joshua Reynolds frequently used it, as have some painters since his day. We cannot suppose that, mixed with oil, it would ever give pigments their proper hardness.
