Page 13 - ... ground during the year, and from the commencement of the rains in June or July until October, the ground is dressed and cleaned by successive ploughings and weedings, and manured to the extent which the means of the cultivator will permit. In the final preparation of the land in October and November, the soil, after being well loosened and turned up by the plough, is crushed and broken down by the passage of a heavy log of wood over its surface, and it is in this state ready for sowing. The amount...
Page 18 - The colour of well-prepared opium is a deep dull brown when viewed in mass, which becomes a bright chestnut brown when a small portion of drug is spread in a thin layer upon a white surface. It adheres to the fingers and draws out to a moderate extent, breaking with a ragged fracture ; should it, however, contain much pussewah, its ductility is much increased, and it is more glutinous. Its smell is peculiar, and perfectly sui generis it is not unpleasant, and in the recent well-prepared drug somewhat...
Page 154 - Acacias are of essential service, either for their durable wood, or for the abundance of tannin in their bark, which has rendered them already useful, or for their gum ; but the latter is even excelled in clearness and solubility by that obtained from PMosporum acacioides.
Page 14 - The smaller and dark-coloured ' leaves' are used in forming the inner portions of the shells of the Opium cakes, whilst the largest and least discoloured ones are kept for furnishing their outside coverings. In a few days after the removal of the petals the capsules have reached their utmost state of development, when the process of collection commences, which extends from about the 20th of February to the 25th of March.
Page 16 - ... earthen pot which the collector carries by his side. After the plant has ceased to yield any more juice its utility is still unexhausted. The capsules are then collected, and from the seeds an oil is extracted which is used by the natives for domestic purposes, both for burning in lamps, and for certain culinary purposes. Of the entire seed a comfit is made, resembling in appearance caraway comfits. Of the dry cake remaining after the extraction of the oil, a coarse description of unleavened...
Page 15 - In using the nutshur only one set of points is brought into use at a time, the capsule being scarified vertically from base to summit. This scarification is repeated on different sides of the capsule, at intervals of a few days, from two to six times. In many districts of Bengal transverse cuts are made in the poppy-head, as in Asia Minor. The milky juice is scraped...
Page 153 - Goodeniaceee, with the exception, perhaps, of a few species, contains a tonic bitterness never recognized before, and discernible in many plants in so high a degree, that I was induced, for this reason, to bestow upon a new genus from the interior the name of Picrophyta ; this property, which indicates a certain alliance to Gentianece, deserves the more consideration, as the true Gentianete.
Page 16 - ... and in the bottom of the vessel which contains it, is found collected a dark fluid resembling infusion of coffee to which the name of Pussewah is given. The recent juice reddens strongly litmus paper, and acts rapidly upon metallic iron, covering it speedily with an inky crust of meconate of iron. The juice when brought home by the cultivator is placed in a shallow earthen vessel which is tilted to such a degree, that all the Pussewah can drain off, and this plan is persevered in so long as any...
Page 91 - It has been found efficient in rheumatism and gout, also as an anthelmintic in cutaneous diseases. Distilled, it is used in the preparation of lac of the finest kind. It burns in lamps like olive oil, and dissolves caoutchouc completely in a short time. Perfumers in Paris use it in large quantities.
Page 90 - Pine-leaves into a sort of a cotton or wool ; the other offers to invalids, as curative baths, the waters used in the manufacture of that vegetable wool. Both have been erected by M. de Pannewitz, inventor of a chemical process by means of which it is possible to extract from the long and slender leaves of the Pine a very filaceous substance, which he has named wood- (or Pine-) wool. It can be curled, felted, and woven.
