_ -- Calcium oxide or lime has been known from a very remote period, and was for a long time considered to be an elementary or undecomposable earth. ❋ Various (N/A)
It seems to me that this reasoning rests on an unscientific use of the term _element_; it rests on giving to that class-name the meaning, _substances asserted to be undecomposable_. ❋ M. M. Pattison Muir (N/A)
A line of demarcation is drawn between _elements_, meaning thereby forms of matter said to be undecomposable but probably capable of separation into unlike parts, and _true elements_, meaning thereby groups of identical undecomposable particles. ❋ M. M. Pattison Muir (N/A)
Since those early days of the century when the electric battery performed its miracles and seemingly reached its limitations in the hands of Davy, many new elementary substances have been discovered, but no single element has been displaced from its position as an undecomposable body. ❋ Unknown (1904)
Some silicates are completely decomposed by such treatment; but it saves time (unless one is sure that no undecomposable silicate is present) to treat these in the same way as the others. ❋ Cornelius Beringer (1886)
So far as our knowledge extends, there are about sixty-six of these undecomposable bodies, of which about one half occurs in but exceedingly minute quantities, and a considerable number of the others exists in comparatively small amounts. ❋ Charles Alexander Cameron (1875)
Torture them as we will in our crucibles; expose them as we please to the highest temperature of a wind furnace, or to the more intense heat evolved by a powerful galvanic battery; subject them to the influence of any agent, or force, or process we may choose, and still they will yield nothing but iron, sulphur, and oxygen: hence these undecomposable bodies are regarded as ❋ Charles Alexander Cameron (1875)
The earliest impressions which the mind can assimilate are the undecomposable sensations produced by resistance, light, sound, etc. ❋ Herbert Spencer (1861)
Putting aside the muscular sense, which had not come into view in Hume's time, the questions arise whether these are all the simple undecomposable materials of thought? or whether others exist of which Hume takes no cognizance. ❋ Thomas Henry Huxley (1860)
The effects which take place when a succession of conducting decomposable and undecomposable substances are placed in the electric circuit, as, for instance, of wires and solutions, or of air and solutions ❋ Michael Faraday (1829)
Where possible, this is of course valuable, but mathematical research is often almost uniquely undecomposable, because the nature of the problem is that it's solution is unknown and hence undecomposable. ❋ Unknown (2009)
"common acceptation" -- "as meaning any cognition reached by an undecomposable mental act." ❋ John Edward Mercer (1889)
