Two or three of those in the stern were placed in contact with some of the electric machinery by which the rudder was usually turned, and through them were sent rapid and energetic currents, whose passage rendered the covering of the wires, notwithstanding their great conductivity, too hot to be touched.

It is also said to control the salt content of the blood upon which its electrical conductivity and other properties depend.

Iodine has been shown to increase the electric conductivity of the brain that is, the rate at which electrons will fly through it.

Adrenalin increases the electric conductivity of the brain.

The electric conductivity of his skin is greater, sometimes a hundred times greater, than the average.

Iodine and thyroid increase the electric conductivity of the brain, so that the memory trace must be deposited more easily in those who have an excess of thyroid.

A curious consequence was pointed out by Maxwell as a result of his theory; namely, that a necessary relation exists between opacity and conductivity, since, as he showed, electro-magnetic disturbances could not be propagated in substances which are conductors of electricity.

Properties of Nervous Tissue Impressibility, Conductivity, Modifiability.

The second property of nerve-cells which is important in study is conductivity.

In nerve tissue, impressibility, conductivity and modifiability are developed to a marked degree.

[Transmission of heat] diathermancy^, transcalency^, conduction; convection; radiation, radiant heat; heat conductivity, conductivity.

2.] A writer, who signs "W.E.H.," in The Electrician of 24th February last, says: "The variation of current arises from a variation of conductivity between the electrodes, consequent upon the variation of the closeness or pressure of contact;" and also, "there must be a variation of pressure between the electrodes when the transmitter is in action.

The varying conductivity of the different strata in relation to heat and electricity may have been an important factor.

In a further article we hope to deal with the effect of hard hats on the conductivity of the branches of the Vth nerve, the mentality of the Hairy Ainus and other cognate questions.

"Either they increase the central energy without affecting the nerves, or they simply increase the available energy by lowering the nervous conductivity; and all of them are unequal and local in their operation.

Transverse and shearing tests; also observations on heat conductivity of sticks over wood fires and a stick exposed to low temperature.

What is the nature of electrical conductivity or resistance, and how is it so greatly and so suddenly changed?
