Few persons, perhaps, would think it susceptible of remarks so curious as are here offered to the reader. For particulars, however, we must refer to the work,

On Oxygen as a Remedy. By M. GRILLE.-It is here said that persons affected by the itch are cured by working in the mine of manganese at Maçon; and M. GRILLE asserts that an ointment of 6 parts of oxyd of manganese and 16 of oxygen cured this disease sooner than Pringle's ointment. He observes that the usual remedies were at the same time administered. The attempt to account for the effect of working in the mine, by help of the diffusion of oxygen in vapour, appears to us injudicious. If the fact be true, it is more likely to be owing to the fine dust of the ore.

Memoir on the Ammoniure of Cobalt, or, on an Acid contained in the grey Oxyd of this Metal usually denominated Saffre. By L. BRUGNATELLI.-This author describes a new acid which he denominates cobaltic acid, though he confessess that its base remains to be ascertained, It is procured, among other methods, simply by boiling saffre in water, and it exists therefore ready formed in that substance.

Report by M. FOURCROY concerning the artificial Mineral Waters prepared by M. PAUL.-The list of waters mentioned. in this paper amounts to eleven; and, which is more surprizing, some of the liquids are said to contain five and six times their bulk of carbonic acid. There is an oxygenated water which contains half its volume of oxygen gas! an hydrogenated which contains a third! and an hydro-carbonated which contains two thirds! The impregnation is effected by strong compression: but the principal part of the machinery is kept secret. In the proportions of impregnating gases, however, there is reason for supposing that the desire of the manufacturer to extol his goods has produced some exaggeration: since the reporters could not extricate the quantity of gas specified. In the case of the oxygenated water, they could not expel one third of the bulk of the oxygen gas with which it was stated by M. PAUL to be impregnated.-Notwithstanding exaggeration, however, (if such it be,) enough is here brought forwards to shew that prodigious improvements in this branch are practicable; and we hope that our chemists and mechanics will turn their attention to it.

We have left unnoticed several papers which appeared to us to be wholly unimportant, or the nature of which rendered them uninteresting to the English reader.-Nos.99 and 100 are just come to our hands: but, as we have not time to report their contents, we must reserve them for our next Appendix.

ART. XII. Nouvelle Methode d'Enseignement, &c. i. e. A new Method of Instruction for early Childhood. By Madame DE GENLIS. 12mo. pp. 426. Hamburgh, &c. 1799. Imported by De Boffe, London. Price 5s. .

HOUGH designed for a younger class of pupils than the former works of Madame DE GENLIS, this volume is said to be the fruit of longer meditation and of more reflection than any that she has before written on the same subject.' The plan is thus explained:

I have here composed dialogues, a tale, some maxims, and little pieces for children. I have written them with simplicity, always sacrificing imagination to morality, and elegance of style to clearness; which necessarily occasions a continual repetition of words. With regard to detached maxims, I have not endeavoured to offer any that are either new or brilliant: my wish has been to trace the first rudiments of morality; and that these seeds, so precious, should result from the dialogues, &c. to the end that they should make the deeper impression.'

Notwithstanding the simplicity of the language, Madame DE GENLIS could not avoid introducing some words which may be beyond the comprehension of a child of six years old; and she has therefore subjoined a list of those which she thought might require explanation, and has given definitions of them.

Les jeux d'enfans, introduced in the last dialogue, are well devised, by making a play of the necessary employments of common life which children may have hereafter to perform; thus teaching them to rehearse their part well, before they are required to act. It is proposed to do this without loss to other instruction, by contriving that it shall form a part of their recreation.

A new method is recommended for teaching young people to design and to paint; which is by instructing and forming their judgment, before they enter on the practical part.

Madame DE GENLIS is of opinion that any child, well edu cated and perfectly managed from its earliest infancy, would appear a prodigy at twenty years of age. The difficulty consists in making the experiment: but, in the endeavour, much good would probably be produced.

From this brief description, and from the known abilities of Madame DE GENLIS, the reader will perhaps be able to appreciate the utility of this work. An English translation of it has appeared; as also of another recent production of this lady's pen, entitled La Brugere the Less: of which we shall shortly give some account.
