Wiother Part (11. Vol. XI.) has appeared of The Edinburgh 
Encyclopedia, conducted by Dr. Brewster. 
The principal articles are, Hybernation, Hydrodynamics, Hy- 
grometry, Jamaica, Japan, Java, Ice, Iceland, Ichthyology, Idria, 
Jedburgh, Jersey, Jerusalem, Jesuits, and Jews. . 
In the article Hydrodynamies, the various subjects of Hydro- 
staties, Specific Gravities, Hydrometers, Equilibrium of Floating 
Bodies, Capillary Attraction and Cohesion, Hydrostatic Instru- 
ments, Hydraulics, Motion of Water in Tubes, Pipes, and Ca- 
nals, Resistance of Fluids, and Hydraulic Machinery, are treated 
ina plain and popular manner, so as to be easily understood by 
those who have but a slight acquaintance with Mathematics.— 
Among the parts of this article which have never before appeared 
in our language, are an account of Laplace’s Theory of Capillary 
Attraction; of Gay-Lussac’s Instrument for measuring the Ascent 
of Water in Capillary Tubes; Venturi’s Experiments on Floating 
Cylinders of Camphor; Girard’s Experiments on the Effect of 
Heat upon the Motion of Fluids; and Prony’s Researches on the 
Motion of Water in Pipesand Canals. ‘The Experiments of Mr. 
Smeaton, on the Motion of Water in Pipes, are here printed, for 
the first time, from the MSS. of that celebrated Engineer, and 
the Description of some new Hydrometers, of Burns’s Overshot 
Wheel without an Axles of Burns’s Sluice Governor; and of the 
Screw Engine, erected at the Hurle:t Alum-works, have never 
before been published. New Tables for facilitating the applica- 
tion of Dubaut’s Formule have also been computed for this article, 
by Mr. Lawrie of Glasgow. he article Hygrometry contains an 
account of the recent investigations of Gay-Lussae and Biot, and 
of many important discoveries made by Mr. Anderson of Perth, 
the author of the article, who has reduced into the form of a 
science a subject hitherto obscure and little understood. 
The article Ice contains an account of the Observations of 
Mr. Scoresby on the Polar Ice; and the article Iceland is written 
by an eminent traveller, who lately yisited that interesting 
island.
