not having perception, or the power of perception. The . . . attributes of an insentient, inert substance. Reid. But there can be nothing like to this sensation in the rose, because it is insentient. Sir W. Hamilton.

trument by means of which the area of a figure can be measured directly, or its moment of inertia, or statical moment, etc., be determined.

An inert gaseous element of the argon group, occurring in air to the extent of about one volume in a million. It was discovered by Ramsay and Travers in 1898. Liquefying point, -- 152º C.; symbol, Kr; atomic weight, 83.0.

Like a lump; inert; gross; heavy; dull; spiritless. " Lumpish, heavy, melancholy." Shak. -- Lump"ish*ly, adv. -- Lump"ish*ness, n.

ns, of which methane is the first member and type, and (because of their general chemical inertness and indifference) called also the paraffin (little affinity) series. The lightest members are gases, as methane, ethane; intermediate members are liquids, as hexane, heptane, etc. (found in benzine, kerosene, etc.); whil…

into the perpendicular distance of its point of application from the plane. -- Moment of inertia, of a rotating body, the sum of the mass of each particle of matter of the body into the square of its distance from the axis of rotation; -- called also moment of rotation and moment of the mass. -- Statical moment, the…

To render inert or imperceptible the peculiar affinities of, as a chemical substance; to destroy the effect of; as, to neutralize an acid with a base.

One who, or that which, neutralizes; that which destroys, disguises, or renders inert the peculiar properties of a body.

s and odorless, comprising four fifths of the atmosphere by volume. It is chemically very inert in the free state, and as such is incapable of supporting life (hence the name azote still used by French chemists); but it forms many important compounds, as ammonia, nitric acid, the cyanides, etc, and is a constituent of…

To make numb; to deprive of the power of sensation or motion; to render senseless or inert; to deaden; to benumb; to stupefy. For lazy winter numbs the laboring hand. Dryden. Like dull narcotics, numbing pain. Tennyson.

, petroleum, etc., by distillation. It is used as an illuminant and lubricant. It is very inert, not being acted upon by most of the strong chemical reagents. It was formerly regarded as a definite compound, but is now known to be a complex mixture of several higher hydrocarbons of the methane or marsh-gas series; henc…

An inert isomeric modification of anthracene.

Inactive; inert; not showing strong affinity; as, red phosphorus is comparatively passive.

In a passive manner; inertly; unresistingly.

ody to remain in a given state, either of motion or rest, till disturbed by another body; inertia. Cheyne.

An inert amorphous white powder, PN2H, obtained by passing ammonia over heated phosphorus. [Spelt also phosphame.] -- Phos"pham"ic, a.

odification of phosphorus, obtained as a gray metallic crystalline substance, having very inert chemical properties. It is obtained by heating ordinary phosphorus in a closed vessel at a high temperature. -- Phosphorus disease (Med.), a disease common among workers in phosphorus, giving rise to necrosis of the jawbone…

a point conceived as being without extension, yet having physical properties, as weight, inertia, momentum, etc.; a material point. -- Physical signs (Med.), the objective signs of the bodily state afforded by a physical examination.

To counteract, as a force, by inertia or reaction.

t of the light platinum group. It is found in platinum ores, and obtained free as a white inert metal which it is very difficult to fuse. Symbol Rh. Atomic weight 104.1. Specific gravity 12.
