Vows;' duet, 'I know a Bank,' by the Semiramide young ladies; fantasia pianoforte, from the Fille du Régiment; 'Rode's air, with variations,' from the text; and the storm movement of the Sinfonia Pastorale, by Beethoven!
Such may be taken as a fair specimen-slice of a Concert Monstre; and in listening to this wild agglomeration of chaotic music, the day passes, very likely from two o'clock until six. In a future paper, I may touch upon the peculiarities of the artists performing.

THE TALLOW-TREE OF CHINA.
It is one happy recommendation of the Natural system of botany, that many of its orders form groups of plants distinguished not only by the characteristics of general physiognomy, and the more accurate differences of structure, but in an especial manner by the medicinal and economical properties which they possess, and which are indeed frequently peculiar to the order. Such is the case with the natural order Euphorbiace?, or spurge family, to which the tallow-tree of China belongs. The order includes 2500 species, all of which are more or less acrid and poisonous, these properties being especially developed in the milky juices which abound in the plants, and which are contained, not in its ordinary tissues, but in certain special vessels. Many important substances are derived from this order, notwithstanding its acrid and poisonous character. Castor-oil is obtained from the seeds of Ricinus communis; croton-oil, and several other oleaginous products of importance in medicine and the arts, are obtained from plants belonging to the order. The root of Janipha Manihot, or Manioc-plant, contains a poisonous substance, supposed to be hydrocyanic acid, along with which there is a considerable proportion of starch. The poisonous matter is removed by roasting and washing, and the starch thus obtained is formed into the cassava-bread of tropical countries, and is also occasionally imported into Europe as Brazilian arrow-root.
Many of the important economical productions of China are little known in this country; we are, however, daily gaining additions to our knowledge of them; and within the last few years, much valuable information has been obtained respecting the productive resources of the Eastern Empire. The grass-cloth of China only became known in Europe a few years ago, but it now ranks as one of the important fabrics of British manufacture. Daily discoveries seem to shew that there are Chinese products of equal importance, as yet unknown to us. On the present occasion, we call the attention of our readers to a substance which has been long known, as well as the plant which produces it, but neither of which has hitherto been prominently brought into general notice in Britain. For our information respecting the uses of the tallow-tree, we express our chief obligations to a paper by Dr D. J. Macgowan, published in the Journal of the Agricultural and Horticultural Society of India.[1]
The tallow-tree of China is the Stillingia sebifera of botanists; a plant originally indigenous to China, where it occurs in wet situations, but which is now somewhat common in various parts of India and America, chiefly as an ornamental tree. In Roxburgh's time, it was very common about Calcutta, where, in the course of a few years, it became one of the most common trees; and it has become almost naturalised in the maritime parts of South Carolina. In China alone, however, is it as yet appreciated as an economical plant, and there alone are its products properly elaborated. It is chiefly prized for the fatty matter which it yields, and from which it derives its appropriate name; but it affords other products of value: 'its leaves are employed as a black dye; its wood being hard and durable, may be easily used for printing-blocks and various other articles; and, finally, the refuse of the nut is employed as fuel and manure.... It grows alike on low alluvial plains and on granite hills, on the rich mould at the margin of canals, and on the sandy sea-beach. The sandy estuary of 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.... They are seldom planted where anything else can be conveniently cultivated--but in detached places, in corners about houses, roads, canals, and fields.'
The sebaceous matter, or vegetable tallow, is contained in the seed-vessels of the Stillingia. The processes adopted for abstracting it are of importance, and meet with due consideration in Dr Macgowan's valuable paper. The following clear account is given of the whole process, as practised in China:--'In midwinter, when the nuts are ripe, they are cut off with their twigs by a sharp crescentric knife, attached to the extremity of a long pole, which is held in the hand, and pushed upwards against the twigs, removing at the same time
