During the middle ages cattle and sheep were the chief farm animals, but the intermixture of stock consequent on the common-field system was a barrier to improvement in the breed and conduced to the propagation of disease.
They are effected chiefly by some alteration in the description of the root-crop, and perhaps by the introduction of the potato crop; by growing a different cereal, or it may be more than one cereal consecutively; by the growth of some other leguminous crop than clover, since " clover-sickness " may result if that crop is grown at too short intervals, or the intermixture of grass seeds with the clover, and perhaps by the extension by one or more years of the period allotted to this member of the rotation.
Yellow Soap consists of a mixture of any hard fatty soap with a variable proportion - up to 40% or more - of resin soap. That substance by itself has a tenacious gluey consistence, and its intermixture in excess renders the resulting compound soft and greasy.
Von Wrangel); the various coloration of many animals according to the composition of the forests they inhabit (the sable and the squirrel are well-known instances); the intermingling northern and southern faunas in the Amur region and the remarkable consequences of that intermixture in the struggle for existence; - all these render the study of the Siberian fauna most interesting.
The native carbonate or cerussite (q.v.) occasionally occurs in the pure form, but more frequently in a state of intimate intermixture with clay ("lead earth," Bleierde), limestone, iron oxides, &c. (as in the ores of Nevada and Colorado), and some times also with coal ("black lead ore").
The unrestricted intermixture of these three races forms the principal basis of the Brazilian population at the beginning of the 10th century.
But from the fact that the bulk of the Tunisian population belongs to the Iberian section of the Berbers, and to this being no doubt the fundamental stock of most Italian peoples, the intermixture of the Italianized Berber with his African brother has not much affected the physique of the people, though it may have slightly tinged their mental characteristics.
Other race mixtures consist of the zambos (the African-Indian cross), an Asiatic graft upon these various crosses, and an extremely confusing intermixture of the various crosses, for which the Spanish races have descriptive appellations.
James Melville (1556-1614), nephew of the more celebrated reformer, Andrew Melville, who was minister of Kilrenny, has given in his Diary a graphic account of the arrival at Anstruther of a weatherbound ship of the Armada, and the tradition of the intermixture of Spanish and Fifeshire blood still prevails in the district.
The serfs were rigidly debarred from intermixture or social advancement, and were watched by their masters with a suspicion fully justified by recurrent ineffectual revolts.
M N Intermixture may take place to any extent, and the more of it there has been the more difficult does it become to trace the transmission of a text.
In beds they can be supplemented as the season passes on by the intermixture of later blooming subjects, such as gladioli.
And in general it may be stated that the hypothesis of such an intermixture of forms from neighbouring dialects has been rendered in recent years far more credible by the striking evidence of such continual intermixture going on within quite modern periods of time afforded by the Atlas linguistique de la France, even in the portion which has already been published.
Plants of this character should be potted a little less firmly than specimens which are likely to stand long in the pot, and indeed the soil should be made comparatively light by the intermixture of leaf-mould or some equivalent, in order that the roots may run freely and quickly into it.
Most likely they were descendants of the Marcomanni, Quadi and Narisci, tribes of the Suevic or Swabian race, with possibly a small intermixture of Gothic or Celtic elements.
The critic has the right of it when he points out, for example, that the practical difficulty in the Method of Agreement is not due to plurality of causes, as Mill states, but rather to intermixture of effects, while, if the canon could be satisfied exactly, the result would not be rendered uncertain in the manner or to the extent which he supposes.
So too, if the canon of the Method of Agreement is never more than approximately satisfied, intermixture of effects will in practice mean that we at least often do not know the cause or antecedent equivalent of a given effect, without the possibility of an alternative.
Be this as it may, the physical appearance of the population of this central region of northern India - Hindustan and Behar - clearly points to an intermixture of the tall, fair-coloured, fine-nosed Aryan with the short-sized, dark-skinned, broad-nosed Dravidian; the latter type becoming more pronounced towards the lower strata of the social order.'
But, on the other hand, the same process of racial intermixture also tended to gradually draw the lower race more or less under the influence of the Brahmanical forms of worship, and thus contributed towards the shaping of the religious system of modern Hinduism.
The Jews are a good example of acclimatization, because they have been established for many centuries in climates very different from that of their native land; they keep themselves almost wholly free from intermixture with the people around them; and they are often so populous in a country that the intermixture with Jewish immigrants from other lands cannot seriously affect the local purity of the race.
Having indicated the chief races of which in various degrees of purity and intermixture the population of Africa is formed, it remains to consider them in greater detail, particu connected by a vertical strip of grassy highland lying mainly to the east of the chain of great lakes.
But as the collection of authentic decretals does not begin till Siricius (385), the pseudo-Isidore first forges thirty letters, which he attributes to the popes from Silvester to Damasus; after this he includes the authentic decretals, with the intermixture of thirty-five apocryphal ones, generally given under the name of those popes who were not represented in the authentic collection, but sometimes also under the names of the others, for example, Damasus, St Leo, Vigilius and St Gregory; with one or two exceptions he does not interpolate genuine decretals.
But even after it has done its best, the original intermixture of things is not wholly overcome.
The Gonds are the most numerous among the aboriginal tribes, but so great an intermixture has taken place between them and the Hindu races that they have lost their language and most of their ethnical characteristics, such as the flat forehead, squat nose, prominent nostril, dark skin, &c., and are scarcely distinguishable from the other classes of the Hindu labouring population.
