So that, were a glass so exactly figured as to collect any one sort of rays into one point, it could not collect those also into the same point, which having the same Incidence upon the same Medium are apt to suffer a different refraction.
The starting-point of discussions as to incidence of taxation is a classical passage in Adam Smith's Wealth of Nations (book v.
To establish, therefore, any fair account of the incidence of indirect taxes on different classes of the community, real classes being distinguished, and not a mere rough grouping into so-called classes of units who are altogether heterogeneous, is probably beyond the skill of man.
In describing the principal taxes which are employed in 'the United Kingdom to provide for the national expenditure, observations have necessarily been made upon the incidence, probable or assumed, upon the taxpayer, and on the question how far they may fall equally on the whole community without any special incidence being traceable.
One difficulty is caused by the large proportion of the taxes in almost every system of taxation, and at any rate in the British system, where the exact incidence is in no way traceable, or where there is no sort of general agreement as to the incidence.
The largest incidence in Bombay was on young adults; but then they are more numerous and more exposed to infection, because they go about more than the younger and the older.
The tres Daciae formed a commune in so far that they had a common capital, Sarmizegethusa, and a common diet, which discussed provincial affairs, formulated complaints and adjusted the incidence of taxation; but in other respects they were practically independent provinces, each under an ordinary procurator, subordinate to a governor of consular rank.
Equality of the angles of incidence and reflection, that the reflected ray QR is such that the angles RQC and CQP are equal; to determine the caustic, it is necessary to determine the envelope of this line.
The determination of the curves of constant retardation depends upon expressing the retardation in terms of the optical constants of the crystal, the angle of incidence and the azimuth of the plane of incidence.
Another exception to the incidence of tithes were abbey lands.
