Seite 145 - The capsules are gently pounded in a mortar, to loosen the seeds from their shells, from which they are separated by sifting. To facilitate th,e separation of the white, sebaceous matter enveloping the seeds, they are steamed in tubs having convex open wicker bottoms, placed over caldrons of boiling water.
Seite 43 - Nepenthes destillatoria. Those present at the meeting, as well as the readers of the ' Philosophical Magazine/ will remember that, in opposition to the statements of most botanists who have directed their attention to the subject of the watery secretions of the leaves of plants, I found the liquid in the ascidia of Nepenthes to differ materially from pure water, inasmuch as it contained from O30 to nearly 1 per cent, of solid substances, partly organic partly inorganic.
Seite 145 - The article thus procured becomes a solid mass on falling through the sieve, and to purify it, it is melted and formed into cakes for the press ; these receive their form from bamboo hoops, a foot in diameter and three inches deep, which are laid on the ground over a little straw. On being filled with the hot liquid, the ends of the straw beneath are drawn up and spread over the top, and when of sufficient consistence, are placed with their rings in the press. This apparatus, which is of the rudest...
Seite 143 - There seems to be no doubt that it is an anomalous state of mould or of some fungus, and the peculiarity of form and consistence appears to be owing to the material in which it grows. In place of producing the usual cellular sporiferous stalks, the mycelium increases to an extraordinary extent; its cellular threads interlacing together in a remarkable manner and producing one expanded cellular mass, with occasionally rounded bodies like spores in its substance.
Seite 128 - The general impression produced by a first glance will be confirmed on farther inspection. The analogy between the skeleton of the leaf and the skeleton of the branch may be seen in a number of points as well as in the general resemblance between the ramification of the plant and the ramification of the venation of the leaf. 1. Some trees, such as the beech, the elm, the oak, the holly, the Portugal and bay laurels, the privet, the box, will be found to send out side branches along the axis from...
Seite 129 - ... tree. Generally, it is the whole leafage coming off at a given place which represents the whole tree, and the single leaf, •when there is a number of leaves, represents merely the branch. 4. Some plants, such as the rhododendron, the azalea, and the lupin, send off leaves which have a tendency to become whorled, and their branches have also a tendency to become verticillate. 5. The stems of some trees, such as the thorn and laburnum, are not straight, and the branches have a twisted form ;...
Seite 145 - Hangchan yields little else. Some of the trees at this place are known to be several hundred years old, and. though prostrated, still send forth branches and bear fruit. Some are made to fall over rivulets, forming convenient bridges. They are seldom planted where anything -else can be conveniently cultivated — in detached places, in corners about houses, roads, canals, and fields.
Seite 94 - Now motioned with his hand for more :Fly to the desert, fly with me! Our Arab tents are rude for thee ; But, oh ! the choice what heart can doubt, Of tents with love, or thrones without ? Our rocks are rough, but smiling there The acacia waves her yellow hair, Lonely and sweet, nor loved the less For flowering in a wilderness.
Seite 151 - Paris zone," the quantity of iodine present in the atmosphere, in the rain-water, and in the soil is comparatively great, and to this he ascribes the absence of goitre and cretinism ; whereas in the zone corresponding to that of the "alpine valleys," the amount of iodine has diminished to one.tenth of that found in the
Seite 236 - ... tests : — Ammonia produced no change. Carbonate of ammonia gave no precipitate. Carbonate of soda on boiling gave a white precipitate. Oxalate of ammonia produced no change. Phosphate of soda and ammonia, added to the concentrated liquid, gave a crystalline white precipitate of phosphate of magnesia and ammonia. Chloride of platinum, added to the concentrated liquid after the removal of the magnesia, produced a crystalline yellow precipitate.
