What is "fluids"

Usage examples of "fluids".

This impairment, as well as the insensibility of six of the leaves, may be attributed to injury from exosmose, caused by the density of the fluids placed on their discs.

The first effect of the carbonate and of certain other salts of ammonia, as well as of some other fluids, is the darkening or blackening of the glands.

So again, if drops of various fluids, for instance of saliva or of a solution of any salt of ammonia, are placed on the central glands, the same result quickly follows, sometimes in under half an hour.

We shall hereafter see that the filaments on the leaves of Dionaea are likewise insensible to the impact of fluids, though exquisitely sensitive to momentary touches from any solid body.

We shall hereafter see what excessively small doses of certain organic fluids and saline solutions cause strongly marked inflection.

If a tentacle is examined some hours after the gland has been excited by repeated touches, or by an inorganic or organic particle placed on it, or by the absorption of certain fluids, it presents a wholly changed appearance.

Other fluids, besides a solution of the carbonate, for instance an infusion of raw meat, produce this same effect.

These effects differ altogether from those produced by the several salts of ammonia, as well as by various organic fluids, and by inorganic particles placed on the glands.

Various nitrogenous organic fluids and salts of ammonia induce aggregation, but in different degrees and at very different rates.

As it was immediately evident that these fluids produced a great effect, I neglected in most cases to record how soon the tentacles became inflected.

Altogether I experimented on sixtyfour leaves with the above nitrogenous fluids, the five leaves tried only with the extremely weak solution of isinglass not being included, nor the numerous trials subsequently made, of which no exact account was kept.

Some of the leaves which were not affected by the nonnitrogenous fluids were, as above stated, immediately afterwards tested with bits of meat, and were thus proved to be in an active condition.

The inflection excited by the other salts of ammonia is probably due solely to their nitrogen,--on the same principle that nitrogenous organic fluids act powerfully, whilst nonnitrogenous organic fluids are powerless.

Drosera is, perhaps, connected with this power, for we have seen that the fluids in which they were immersed often became pink, and the glands palecoloured or white.

We have here to consider the effects of immersion in various fluids on the subsequent action of salts of ammonia and other stimulants.
