Under this class is included arithmetic, or the art of computation; geometry, or the science of mensuration, and comparisons of all kinds of extensions; analysis, or the calculations and comparisons of magnitudes in general; and lastly, geometrical analysis, or the combination of elementary geometry and analysis.. Mixed Mathematics, are certain parts of physics, w Inch are by their nature susceptible of being submitted to mathematical investigation; we here borrow from incontestible experiments, or suppose in bodies, some principal ami necessary quality, and then by a methodical and demonstrative chain of reasoning deduce, from the principles established, conclusions as evident and certain, as those which is nearly double that of the sun. Pure mathematics draw immedi At the poles of this planet there has been observed bright spots which are, however, variable in (heir size and fig me; and from the observations ol Dr. Herschel, it seems probable that they proceed from snows accumulated in his polar regions during their long winter, these having been observed to decrease and increase, according as they are directed to or from the sun. MASS, the quantity of matter in any body, which is always proportional to, and may be truly estimated by its weight, whatever be its figure or magnitude. MATHEMATICAL, relating to mathematics. MATHEMATICS, the science of magnitudes or quantities; or of the ratios, or relations of magnitudes or quantities. The subjects which fall to be considered under the different departments of Mathematics are spaces, distances, numbers, motions, velocities, and, in 'short, whatever is susceptible ot being measured. 303 ately from axioms and detinitioiif.
