The general principle of dynamics developed here, of which I have already treated, and which I have applied to different examples of analytical mechanics, in two little German works intitled Os Analytische Bestimmung des Gesetezes der virtuellen Geschwindigkeiten,' &c. and “Weitere Entwickelung und Anwendung des Gesetzes der virtuellen Geschwindigkeiten," &c. is sufficient of itself to resolve all the questions of dynamics and statics; without its being necessary previously to consider whether the problem belongs to dynamics or statics, or to employ in the two cases two different principles. Under the point of view in which dynamics is here developed, statics forms not a separate part; the static state being only a particular case of dynamics in general, of which cases we may imagine an infinite number. This principle of dynamics rests on none of the principles of mechanics or statics at present known.'
This new theory is made to depend on the following consi. derations; viz. suppose a system of bodies, b, b', b”, &c., to which are applied divers individual dynamic impulsions, i, i, i', &c.; and let us farther suppose that these points of appliçation are so arranged that the space run over by one of them shall decide the space run over by all the others (as well in direction as in distance),' then the combined motion of the system may be considered by merely contemplating that of an individual point. Such a new principle of mechanics is something like the old principle of catching birds by laying salt on their tails; — at least, the practicability appears to us to be nearly the same in both cases.

Jews of the Nineteenth Century, or Considerations on their Civil and political State in Europe; followed by a Biographical Notice of those Antient and Modern Jews who have distinguished themselves in the Sciences and Arts. By M. BAIL, formerly Inspector of Reviews, and Member of the Legion of Honour. Second Edition, revised and corrected by the Author. 8vo. pp. 148. Paris. 1816. THE situation of the Jews has in the present age excited
considerable attention; various attempts having been made by benevolent individuals to convert them to Christianity, and to lessen the existing prejudices against their name and character. Bonaparte chose to take up the subject about twelve years ago with more than common warmth; in the hope, no doubt, of making this oppressed race useful in his military schemes, particularly in his views on Poland. Influenced by different motives, M. Bail, without belonging to the Hebrew nation, now comes forwards as their zealous advocate; dwelling with great emphasis on the persecutions which they endured in former times, as well as on the humi
