If the overaction or excess of secretion begins in childhood or adolescence, that is, before puberty, there results a great elongation of the bones, so that a giant is the consequence.

One of the desiderata which I had pointed out in my Report on Astronomy was the determination of the mass of Jupiter by elongations of the 4th satellite: and as the Equatoreal of the Cambridge Observatory was on the point of coming into use, I determined to employ it for this purpose.

During the last winter I had well employed the Equatoreal in observing elongations in R.A. of the 4th Satellite.

By the elongation of the florets in the centre.

Many plants, like many animals, are furnished with arms for their protection; these are either aculei, prickles, as in rose and barberry, which are formed from the outer bark of the plant; or spinæ, thorns, as in hawthorn, which are an elongation of the wood, and hence more difficult to be torn off than the former; or stimuli, stings, as in the nettles, which are armed with a venomous fluid for the annoyance of naked animals.

Q.And what is meant by the lap of the valve? A.It is an elongation of the valve face to a certain extent over the port, whereby the port is closed sooner than would otherwise be the case.

Some such increase is obviously inevitable, if a similar form of flue be retained in the larger and smaller powers, and at the same time the elongation of the flue in the same proportion as the increase of any other dimension is prevented; but in the smaller class of wagon boilers the consideration of facility of cleaning the flues is also operative in inducing a large proportion of sectional area.

The space thus left enables the bars to expand without injury on the application of heat, whereas without some such provision the bars are very liable to get burned out by bending up in the centre, or at the ends, as they must do if the elongation of the bars on the application of heat be prevented; and this must be the effect of permitting the spaces at the ends of the bars to be filled up with ashes.

The effect of this arrangement is to lengthen the rod, but at the cross head end of the rod the elongation is neutralized by making the strap loose, so that in tightening the brass the rod is shortened by an amount equal to its elongation at the crank pin end.

For this latter purpose several observations were in the first place made upon the polar star ([Greek: alpha] Ursae Minoris) when at its greatest eastern diurnal elongation, and the direction thus obtained was afterwards verified and corrected by numerous transit observations upon stars passing the meridian at various altitudes both north and south of the zenith.

The first is merely that of elongation of the epithelial processes into the connective tissue, until the rete Malpighii gives one the impression that it has hanging to its underneath surface and into the corium a number of thorn-like processes.

Accompanying this elongation of the processes is a condensation of the epithelial cells immediately above the rete Malpighii, with a partial or total loss of their nuclei.

The deflecting power exerted by the elastic bond is also increased by its elongation.

If, however, the strength of the deflecting bond is increased by its elongation in a more rapid ratio than the centrifugal force is increased by the enlargement of the circle, then a point will be reached in which the centripetal force will be sufficient to compel the body to move again in the circular path.

When the sample is forced through the tube near the flame, gas if present at once reveals itself by the elongation of the flame in the usual way, at the same time giving an additional proof by burning with a blue flame on the top of the test tube.

Such a casting, if free from other impurities, would have a strength of between 30 and 40 tons, and on an 8 inch specimen would give an elongation of 20 per cent.

The face of the saint is so attractive that one forgets the elongation of her figure.

Within the elastic limit the elongations and shortenings are equal, and the neutral plane lies in the middle of the beam.

As a result the shortenings on the upper side of the beam become considerably greater than the elongations on the lower side.

'[10] Conceivably the elongation of Home and the ancient Egyptian mediums may have been an extreme case of this 'change of volume.'

Could this be proved by examples, Home's elongation would cease to be a 'miracle.'

The results are given for twenty-two examples, about one-half of which have stood well, while the remainder have either broken, split, or suffered considerable abrasion in wear; but in many instances the mechanical test of tensile strength, elongation, and contraction, and the figures of quality (Wohler's sum and Tetmajer's coefficient) deduced from these have varied very considerably for the results obtained in practice.
