Propagation facilities are being greatly improved, and there are stringent laws for the protection of immature fish.

John was sent out by the Society for the Propagation of the Gospel, and hoped to labour as a missionary among the Indians, but though he had many interesting conversations with them the mission was found to be impracticable.

His only published works are two sermons, one preached before the Lords (London, 1794), the other before the Society for the Propagation of the Gospel (London, 1797).

Propagation is by the formation of new corms from the parent corm, and by seeds.

His prize subjects were, the capstan, the propagation of light, and the magnet.

They found that the velocity of propagation of different musical sounds was the same.

He suggests that the propagation of earthquake disturbances is probably affected by the curvature of the surface of the globe, which may act like a whispering gallery.

That which we term the Record of the Past comprises the " taboos,' the customs, the traditions, the beliefs, the knowledge which are handed on by one generation to another independently of organic propagation.

No attempt should ever be made to raise large crops of tobacco from imported seed, but only a small crop, and the seed of the selected plants should be used for future propagation.

The manifold plate is then heavily punched from one side, so that the opposite face protrudes in broken blisters, which are then hammered down until each becomes a centre of wave propagation.

The motion of a particle of air is, as represented in these illustrations, to and fro in the direction of propagation, i.e.

If we take one of these spheres a distance from the source very great as compared with a single wave-length, and draw a radius to a point on the sphere, then for some little way round that point the sphere may be regarded as a plane perpendicular to the radius or the line of propagation.

Every particle in the plane will have the same displacement and the same velocity, and these will be perpendicular to the plane and parallel to the line of propagation.

Hence sound rays, in passing from one medium into another, are bent in towards the normal, or the reverse, according as the velocity of propagation in the former exceeds or falls short of that in the latter.

The vibrations of certain sources of sound may be represented, at least as a first approximation, as consisting of stationary waves, and from a consideration of the rate of propagation of waves along these sources we can deduce their frequency when we know their length.

We shall find the velocity of propagation, just as in previous cases, from the consideration of transfer of momentum.

The velocity of propagation of a torsional disturbance along a wire of circular section may be found by the transfer of momentum method, remembering that we must now replace linear momentum by angular momentum.

If, instead of considering one point in a succession of instants, we consider a succession of points along the line of propagation at the same instant, we evidently have waves of amplitude varying from 2a down to o, and then up to 2a again in distance U/(ni - n2).

The only aether which has survived is that which was invented by Huygens to explain the propagation of light.

Real-time dynamic system for monitoring ionospheric propagation conditions over europe.

The topics covered range from antennas, through radiowave propagation, optics and radar, to communications signal processing and networks.

With all the important work he accomplished in physics - the enunciation of Boyle's law, the discovery of the part taken by air in the propagation of sound, and investigations on the expansive force of freezing water, on specific gravities and refractive powers, on crystals, on electricity, on colour, on hydrostatics, &c. - chemistry was his peculiar and favourite study.

In some of the genera parthenogenetic propagation is carried to such an extent that of the familiar Cypris it is said, " until quite lately males in this genus were unknown; and up to the present time no male has been found in the British Islands " (Brady and Norman, 1896).

This Society, instituted to this special end, namely, to offer spiritual consolation for the advancement of souls in life and Christian doctrine, for the propagation of the faith by public preaching and the ministry of the word of God, spiritual exercises and works of charity and, especially, by the instruction .of children and ignorant people in Christianity, and by the spiritual, consolation of the faithful in Christ in hearing confessions...."

In this original scheme it is clearly marked out "that this entire Society and all its members fight for God under the faithful obedience of the most sacred lord, the pope, and the other Roman pontiffs his successors"; and Ignatius makes particular mention th4t each member should "be bound by a special vow," beyond that formal obligation under which all Christians are of obeying the pope, "so that whatsoever the present and other Roman pontiffs for the time being shall ordain, pertaining to the advancement of souls and the propagation of the faith, to whatever provinces he shall resolve to send us, we are straightway bound to obey, as far as in us lies, without any tergiversation or excuse, whether he send us among the Turks or to any other unbelievers in being, even to those parts called India, or to any heretics or schismatics or likewise to any believers."

It can be shown mathematically that the velocity of propagation will be greatly increased if the frequency of the light-wave is slightly greater, and greatly diminished if it is slightly less than the natural frequency of the molecules; also that these effects become less and less marked as the difference in the two frequencies increases.

The fundamental assumption is that the medium contains positively and negatively charged ions or electrons which are acted on by the periodic electric forces which occur in wave propagation on Maxwell's theory.

Moreover, though each natural substance is corruptible (40apr6v), species is eternal (&t&ov), because there was always some individual of it to continue its original essence (expressed by the imperfect tense in TO TI Etvae), which is ungenerated and incorruptible; the natural world therefore is eternal; and nature is for ever aiming at an eternal propagation, by efficient acting on matter, of essence as end.

It would therefore seem to be more appropriate to replace 1 - K- 1 by (2 - I)1112, where j s is the refractive index; but this expression involves the wave propagation for periods coinciding with free periods of the molecules.

He was one of the founders of the Society for the Propagation of the Gospel.

Though these writings are mostly the same in origin as are known from the older lists of apocryphal books, they underwent in this case a certain modification at the hands of their Bogomil editors, so as to be used for the propagation of their own specific doctrines.

St Basil's influence, and the greater suitability of his institute to European ideas, ensured the propagation of Basilian monachism; and Sozomen says that in Cappadocia and the neighbouring provinces there were no hermits but only cenobites.

The philosopher Thomas Harriot (1560-1621), one of his colleagues, laboured for the conversion of the natives, amongst whom the first baptism is recorded to have taken place on the 13th of August 1587.9 Raleigh himself presented as a parting gift to the Virginian Company the sum of loo " for the propagation of the Christian religion " in that settlement.

For now the corporation was styled " The Propagation of the Gospel in New England and the parts adjacent in America," and its object was defined to be " not only to seek the outward welfare and prosperity of those colonies, but more especially to endeavour the good and salvation of their immortal souls, and the publishing the most glorious gospel of Christ among them."

He contributed to the expense of printing and publishing at Oxford the four Gospels and the Acts of the Apostles in the Malay language, and at his death left 5400 for the propagation of the gospel in heathen lands.

Both the Society for the Propagation of the Gospel and the Church Missionary Society were at that time suffering from a general coldness which, in the case of the latter society, had led in that very year to the committee reporting " a failing treasury and a scanty supply of men."

Another influence upon university men and others who have taken holy orders is that of the Younger Clergy Union of the Church Missionary Society (1885) and the Junior Clergy Association of the Society for the Propagation of the Gospel (1891).

It soon appeared, however, that neither the Society for the Propagation of the Gospel nor the Church Missionary Society was willing to be absorbed; and it was urged by some that in a great comprehensive national Church, comprising persons of widely different views, more zeal was likely to be thrown into voluntary than into official enterprises.

The Society for the Propagation of the Gospel came in 1819, mainly for colonists, the Church Missionary Society in 1837.

West Africa was first visited by the Society for the Propagation of the Gospel in 1752.

In the Straits Settlement the foundations of modern missionary effort were laid by the London Missionary Society pioneers who were waiting to get into China; they were succeeded by the Society for the Propagation of the Gospel (1856), English Presbyterians (1875), Methodist Episcopalians (1884), who have a fine Anglo-Chinese College at Singapore, and the Church of England Zenana Society (1900).

In Dutch Borneo the Rhenish Society is slowly making headway among the Dyaks; in British Borneo the Society for the Propagation of the Gospel (1848) and the Methodist Episcopalians occupy the field.

In some instances buds form on the roots, and may be used for purposes of propagation, as in the Japan quince, the globe thistle, the sea holly, some sea lavenders, Bocconia, Acanthus, &c. Of the tendency in buds to assume an independent existence gardeners avail themselves in the operations of striking " cuttings," and making " layers " and " pipings," as also in budding and grafting.

For evergreens August or September, and for greenhouse and stove-plants the spring and summer months, are the times most suitable for propagation by cuttings.

Those most suitable for the purpose of the gardener are carefully selected for propagation, while others not so desirable are destroyed; and thus after a few generations a fixed variety, race or strain superior to the original form is obtained.

When used for propagation, the tubers are cut up into what are called " sets," every portion having an eye attached being capable of forming an independent plant.

The cut portions of bulky sets should be suffered to lie a short time before being planted, in order to dry the surface and prevent rotting; this should not, however, be done with such tropical subjects as caladiums, the tubers of which are often cut up into very small fragments for propagation, and of course require to be manipulated in a properly heated propagating pit.

For propagation the bulbiferous portion is pegged down on the surface of a pot of suitable soil; if kept close in a moist atmosphere, the little buds will soon strike root and form independent plants.

For the propagation by grafts of stove and greenhouse plants the process adopted is whip-grafting or a modification of it.

Root-grafting is sometimes resorted to where extensive increase is an object, or where stem-grafting or other means of propagation are not available.
