Nevertheless, a large number of the specimens collected in Ecuador are intermediate in color as well as in zonal distribution.
The existence of zones horizontally or areally arranged about intrusives suggests also the possibility of a vertical zonal arrangement with reference to the deep sources of the solutions.
A zonal arrangement of minerals about intrusives is often noted.
The further investigation of this primary zonal arrangement promises interesting results with a practical bearing on exploration and development.
Of course when secondary concentration from the surface, described later, is taken into account, there may be a marked zonal distribution in a vertical direction, but this is not primary zoning.
For this purpose projections are drawn, with the aid of which the zonal relations of a crystal are more readily studied and calculations are simplified.
True perspective drawings are never used in the representation of crystals, since for showing the zonal relations it is important to preserve the parallelism of the edges.
The zonal or bedding race, on the other hand, has been more recently perfected; they are supposed to have arisen from hybrids between Pelargonium inquinans and P.
The zonal varieties, which are almost continuous bloomers, are of much value as decorative subjects; they seldom require much pruning after the first stopping.
In fact it may be said that, from a popular point of view, the pelargoniums of the botanist are still better known as geraniums than are the geraniums themselves, but the term "zonal Pelargonium" is gradually making its way amongst the masses.
For bedding purposes the zonal varieties are best struck towards the middle of August in the open air, taken up and potted or planted in boxes as soon as struck, and preserved in frames or in the greenhouse during winter.
The fancy varieties root best early in spring from the half-ripened shoots; they are slower growers, and rather more delicate in constitution than the zonal varieties, and very impatient of excess of water at the root.
What is known as a zonal distribution in organisms only occurs in anthropology when a district is inhabited by different peoples that live concentrically to one another.
This is especially evident when the bead is decorated with a twisted design, as occurs in the zonal decoration of a bronze vessel from a Swiss lake-dwelling.
Yet the mesh rises superior to zonal solicitation as to local barrier.
Rotational, climatic, or other physical cause could not fail of zonal expression.
To perceive the tropical character of the doubles in another way we have but to consider the zonal distribution of the single canals.
More often than not they show a density exceeding that of the nearest mainland having the same zonal location, often the same geologic structure and soil.
Here is no diversity of outward form, no contrast of zonal location, no fructifying variety of geographic conditions.
Even when the boundary line has been surveyed and the boundary pillars set up, the frontier is prone to assert its old zonal nature, simply because it marks the limits of human movements.
Even the most general statement of the zonal and interoceanic situation of Canada, the United States, Mexico, and the Russian Empire, indicates the area and contour of their territories.
South of the equator the native Bantu Kaffirs, essentially a tropical people, spread beyond their zonal border to the south coast of Africa at 33° S.
Without stopping to discuss the obvious results of a contrasted zonal location, such as that between Labrador and Yucatan, the Kola Peninsula and Spain, it is necessary to keep in mind always the effect of vicinal location.
Zonal range: Upper Austral (Upper Sonoran and Carolinian) and Transition (Alleghanian and Transition).
Zonal range: Upper Sonoran areas that are moist yet safe from continuous inundation.
Strange to say, they need only the ordinary course of cultivation of the winter-flowering Zonal Pelargonium; hitherto they have been treated as a stove plant, whereas they only need a temperature not higher than 50 deg.
I notice, both in your letter-press and advertisement, mention made of Zonal Pelargoniums; now I should certainly decline to receive Geraniums if I ordered Pelargoniums.
By the side are shown the principal zonal ammonites, and, for comparison, the subdivisions preferred by Messrs Tate and Blake and by A.
Many ammonites occur in this formation in addition to the forms used as zonal indexes mentioned in the table.
The group is poor in fossils with the exception of graptolites; of these Cyrtograptus grayae and Monograptus exiguus are zonal forms.
The fossils of the Llandeilo group include numerous graptolites, Coenograptus gracilis being taken as the zonal fossil of the upper portion, Didymograptus Murchisoni of the lower.
The numbers are most easily seen if the smallest circle on the surface of the ring, which circle is concentric with the axis, be one of the zonal circles.
From a perfect magic ring of n^2 cells containing one number each, n^2 distinct magic squares can be read off; as the four numbers round each intersection of a zonal circle and a transverse circle constitute corner numbers of a magic square.
From this it is argued that the zonal field is concerned with memories and recognitions of a kind based on visual perceptions.
This zonal field is small in the lower apes, and hardly discoverable in the dog.
Lapworth to furnish a useful basis for zonal subdivisions.
The brachiopods and trilobites have likewise been made use of for zonal purposes among the oldest sedimentary formations.
This zonal crowding would be of special importance in summer, at which time it would also be most pronounced.
Putting together the evidence on both sides in this disputed question, it appears that throughout most of geological time there is some evidence of a zonalarrangement of climate.
Moreover, the progressive increase in the height of the lands has presumably played a part in fostering local and zonal diversity in contrast with the relative uniformity of earlier geological times.
Local as well as zonal contrasts are also intensified.
Zonal structure is characteristic, being noticeable even without the use of polarized light.
The zonal fossils are Perisphinctes arbustigerus and Macrocephalus subcontractus with Ostrea acuminata, Rhynchonella concinna and Goniomya angulifera.
The sections of the crystals themselves are also frequently bounded by irregular outlines, but they often show internally delicate zonal markings, as indicated in Fig.
And here I was condemned to ennui and indolence when I might have been sitting up all night dosing the Zonal Pelargoniums with hot beef-tea and taking the temperature of the Campanula pyramidalis.
The chief plants in flower will be Lantanas, Campanula pyramidalis, Zonal Pelargoniums," and about twenty more.
In looking over a large series of the vases it will be seen that the tendency of decoration is toward the zonal arrangement, the spaces being narrow and long, even when divided into the usual number of panels.
The first forms part of the incised ornament of a small vase or needlecase and the second is a section of the zonal ornament of the tripod cup illustrated in Fig.
Spherical aberration may be located by using stops and zonal screens, and observing the effect on the image.
This may be due to uncorrected spherical aberration, particularly to a fault known as "zonal aberration," where different zones of the lens have different foci, but each zone has a definite focus.
In this case the disc may be partially screened by zonal screens, and the position of the image for different zones noted; the correctness or otherwise of the curvature may then be ascertained by calculation.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "zonal" in a variety of sentences. We hope that you will now be able to make sentences using this word. Other words: geographic; geographical; regional; sectional; topographic
