Sample of cordage from Manilla hemp.
[Manilla hemp is not derived from the flax plant Linumusitatisskrmm, known in the other countries, but from aspecies of banana, Musa textilis . This tree is a native oftropical plains, and is most valuable for its general products.The fibrous material found in the bark is made into a cloth,and also into cordage. Tins flax-like substance is highlyvalued for textile purposes, and some of the finest muslinsof the East are formed of it. Its use for cordage is alsoimportant, and the ropes made from it are winter thanthose made from ordinary flax.—R. E.]

A variety of daguerreotypes.
[The Americans, from the first announcement of thewonderful art of sun-painting, have zealously made the sub-ject one of much patient experiment. The first portraitsfrom life were taken by the daguerreotype, in New York ,and a variety of valuable manipulatory processes haveoriginated in that country. The success with which theart is practised, and the degree of perfection to which ithas been brought, may be estimated by the specimensexhibited by various artists. The brilliancy and sharp-ness of some of these are highly remarkable. Of late anAmerican has announced the discovery of a method ofobtaining coloured pictures from nature, the ordinarycolours being communicated by a brush. The process isnot, however, published. M. Becquerel, a Erench chemist,has partially succeeded in obtaining a coloured impres-sion on plates; and, more recently still, photographsin natural colours have actually been exhibited in thiscountry. These remarkable pictures are taken by a pro-cess discovered by a relative of M. Niepce, the originatorof those principles which were brought to a successfulaccomplishment by Daguerre . The ordinary daguerreo-type process only produces pictures with light and shade.—R. E.] _
