LITERARY NOTICES, &c.

Several notices of Works recently published have been sent to us which we cannot insert. Authors and publishers who desire to see their PUBLISHED works noticed in our Journal must send copies of such works, as we have before requested, to Messrs. Sherwood and Co., Paternoster Kow.

MR. P. W. WATSON, of Hull has been engaged in the vicinity of London, since the spring of 1820, in collecting materials for a Dendrologia Britannica, or trees and shrubs that will live in the open air of Britain during the whole year, to be illustrated by original descriptions and coloured plates from living plants. One hundred and ten coloured octavo drawings by eminent artists, with occasional minute dissections are already completed of such hardy trees and shrubs as have not, a few excepted, been figured by recent respectable botanists.

A new society is about to be formed under highly auspicious circumstances for the encouragement and promotion of the science of entomology.

Gems, principally from the antique, with verse illustrations by the Rev. G. CROLY, M.A. drawn and etched by R. DAGLEY, are preparing for publica

tion.

Mr. PONTEY's Practical Treatise on Rural Ornament, which deduces the science from well-known fixed principles, will appear in the course of the present month.

Mr. J. G. WALKER has just published a print of Mr. Stothard's cele brated picture of the senior scholars of Christ's Hospital delivering their orations on St. Matthew's day; report speaks highly of this engraving.

M. SIEBER is about to publish in two volumes, octavo, an Account of his Visit to the Island of Crete, with plates and maps.

Spade Husbandry.-By an experiment Jately made to ascertain the difference between the use of the spade and the plough, the superiority of the spade has been unequivocally demonstrated. Of a field which was in beans last year and oats the year before, two ridges were dug and two ploughed alternately: the whole was sown on the same day;

a part both on the ploughed and dug being drilled with the garden hoe. The whole was reaped the same day; and, being thrashed out, the dug, sown broadcast, was to the ploughed, sown broadcast as fifty-five to forty-two. The dug and drilled was as twenty and a quarter to twelve and a quarter upon the ploughed and drilled. Besides the additional quantity of grain, there was also more straw, and the land was free from weeds.

Dr. ZIMMERMAN, professor of chemistry in the university of Giessen, has discovered that all the aqueous atmospherical precipitates or deposits, as dew, snow, rain, and hail, contain meteoric iron, usually combined in the same manner as meteoric stones with nickel. Most of the rains examined contained common salt, and a new or ganic substance composed of hydrogen, oxygen, and carbon; this the Dr. calls Pyrine. Rain-water was often found also to contain various kinds of earths. From contemporary observations made on various eminences, the results are in favour of the opinion, that the stony meteoric masses are of telluric and not of cosmic origin.

A correspondent in the Annals of Philosophy will be obliged by any objection to the following definition of a straight line. A straight line is such as being divided or produced to any extent is still directed towards the same points. We do not desire to make this journal an arena of controversy, but we think this gentleman, upon a little reflection, must see that the definition is by no means so simple or explicit as could be desired. What has a line's being divided to do with the proof of its straightness? The great fault of all definers, from Dr. Johnson downwards, is, that they forget that definitions are wanted chiefly for the simple and unlearned.

To JOHN CHRISTOPHERS, of New Broad-street, London, for certain improvements on, or a substitute or substitutes for, Anchors.

THESE improvements consist in the construction of certain peculiarly formed anchors, or substitutes for anchors, represented in Plate VII. Fig. 1 and 2, are different views of an anchor, slightly varied in form from the common anchor; a, a, is the shank consisting of two eliptical bars, set at an angle to each other, but which are united, and square at the upper part where the shackle is introduced; b, b, are the arms to which the lower parts of the shank bars are riveted, bolted, or otherwise secured; c, c, are the palms of the anchor of the ordinary form, but are recommended to be circular at their back part as dotted; d, d, is the stock of wrought

iròn, or it may be of wood, as usual; which is intended occasionally to be introduced through the hole f, in the middle of the arms b. This anchor, with the branching shank, is considered to be much stronger in proportion to its weight than a common anchor, and is better calculated to resist, during the operation of tearing or wrenching the anchor out of the ground, as the two branches of the shank mutually support each other; and also the arms, or flukes, are less liable to be broken, in consequence of the shank being connected thereto nearer to the point of the palms, than in the common anchor.

Fig. 3, 4, and 5, exhibit different views of another formed anchor, which is proposed as a substitute for the common anchor. It is furnished with two double palms, connected by a cross bar; a, is the shank, divided as before; b, is the curved cross bar, or arm, to which the ends of the shank a are riveted or bolted; c, c, are the double flukes, or palms of an oval form, connected by the curved cross bar, or arm b. This form of anchor possesses considerable advantage over the ordinary anchor, as it requires no stock, and is capable of taking very firm hold of the ground, by having two of its palms in operation at once. It is also superior to the common anchor in strength, as it will sustain a very great lateral strain, as the ship swings about when riding at single anchor, and is less liable to foul or entangle with the cable.

Fig. 6 and 7 are representations of another formed anchor, which may be called a mushroom anchor; it is chiefly made of cast-iron. a, a, a, are three branching bars of wrought-iron, arranged in a triangular position; they are united, and form a square at the top where the shackle passes through, and, at their lower ends, enter
