One curious result we select In mention from the many details of the paper; less motion of the palate occurs in saying 'mamma' than 'papa.' Dr. Alien suggests that the smaller efTorl required may be one cause of children usiully learning the former word first. Like nil Dr. Allen's work, this also Is excellent.

— The Jotirnal of the IroD and steel Institute sums np the known distribution of iron ore in north-west Africa as foliowi: "In Morocco there are beds of liematlle of considerable size, and their continuity and re-appearance westwards is now an ascertained fact. Commencing from the Tunisian frontier, the Mediterranean seaboard offers an abundance of pay- able ore at various points, and these deposits were very extensively worked by the Romans, forming iii- deed their main supply. Tbe moat productive Alge- rian mines furnish a spathic carbonate containing sixty per cent of ferrous oxide, and a hematite con- taining ninety-two per cent of ferric oxide. The com- position of the Algerian ore is exceedingly uniform, and it is almost entirely fn-e from sulphur and plios- phorus. These beds re-appear as far west as the con- flnss of the provinces of llihomina and Dukkala in South Morocco. The deposits consist of red hema- tlta, and show an outcrop of very extensive area. Specimens brought from the Sahara caravan route either to TaBlelt orTinibuctoo prove the re-appear- ance of these iron-ore beds south uf the Atlas ranges."

— Tbe modern Uiathematlcian linds the space of rhree dimensions. In whicb our visible universe is contained, entirely too contracted tor his conceptions, and is obliged to Imagine a space of n dimensions In order that his fancy may find room to disport itself. But It is a new Idea, on the part of the novelist, to make the coucepiions of Iranacenilental geometry the iMsii for an onuislng story. ' Flattand, a romance' of many dimensions, by A. Square ' (Boston, Hobertu tiTOthers, 188-5), is lu sulntanco a description of life as a geometer might imagine It to be In space of one, two, or n dimensions. Headers of ' Alice behind ttin looking-glass ' will not fail to notice the resemblance of the present work to that singular play of fancy- Curiously enough, a' scientific romance 'on thcfuurth dimension is just now announced In England by C H. HIntoii.
