For high southern latitudes special value in the American method was useless for this purpose.

In intermediate latitudes there is a loss of heat and then the increased density due to equatorial concentration becomes a factor.

Russia the summer is much warmer than in the corresponding latitudes of France, and really hot weather is.

Shore Deposits are the product of the waste of the land arranged and bedded by the action of currents or tidal streams. On the rocky coast of high latitudes blocks of stone detached by frost fall on the beach and becoming embedded in ice during winter are often drifted out to sea and so carry the shore deposits to some distance from the land.

There will be great outbursts of polar ice, but this will melt at higher latitudes than in the periods when the tide-generating force is minimal.

The birds of Australia in their number and variety of species may be deemed some compensation for its poverty of mammals; yet it will not stand comparison in this respect with regions of Africa and South America in the same latitudes.

This wealth of plant life is confined to the littoral and the coastal valleys, but the central valleys and the plateaux have, if not a varied flora, a considerable wealth of timber trees in every way superior to the flora inland in the same latitudes.

A similar zone surrounds the permanent snow on lofty mountains in all latitudes.

Since the difference between the acceleration of gravity at the pole and at the equator is about 2%, the correction for latitude will be quite sensible in an instrument which might be used at various times in high and low latitudes.

The indiscriminate use of Mercator's projection, for maps of the world, is to be deprecated owing to the inordinate exaggeration of areas in high latitudes.

Two broods seem to be common in the course of the season, and towards the end of summer the birds - the young greatly preponderating in number - collect in large flocks and move to the sea-coast, whence a large proportion depart for more southern latitudes.

Ephemeridae are found all over the world, even up to high northern latitudes.

The bottom water is relatively rich in these substances as well as in decaying organic matter, and would become progressively richer but for the slow drift towards the equator and the welling-up of bottom water to the surface in these latitudes.

Such old sea-ice when prevented from escaping forms the palaeocrystic sea of Nares; but, as a rule, it is carried southward in the .East Greenland and Labrador currents, and melted in the warmer seas of lower latitudes.

Diatom ooze has been found in detached areas between the Philippine and Mariana islands, and near the Aleutian and Galapagos groups, forming an exception to the general rule of its occurrence only in high latitudes.

The central section of the Great Plains, between latitudes 42 and 36, occupying eastern Colorado and western Kansas, is, briefly stated, for the most part a dissected fluviatile plain; that is, this section was once smoothly covered with a gently sloping plain of gravel and sand that had been spread far forward on a broad denuded area as a piedmont deposit by the rivers which issued from the mountains; and since then it has been more or less dissected by the erosion of valleys.

In virtue of these physical characteristics, the air over the land becomes much warmer in summer and much colder in winter than the air over the oceans in corresponding latitudes; hence the seasonal changes of temperature in the central United States are strong; the high temperatures appropriate to the torrid zone advance northward to middle latitudes in summer, and the low temperatures appropriate to the Arctic regions descend almost to middle latitudes in winter.

In summer the stormy westerly winds withdraw from these lower latitudes, which are then to be more associated with the trade winds.

He accepted also the division into five zones; he quotes approvingly the assertion of Hipparchus that it was impossible to make real advances in geography without astronomical observations for determining latitudes and longitudes.

They are as a rule of a very hardy character, thriving best in northern latitudes - the trees having round, slender branches, and serrate, deciduous leaves, with barren and fertile catkins on the same tree, and winged fruits, the so-called seeds.

The leaves are used as fodder in northern latitudes.

Some are littoral, living between tide-marks; others are found at very various depths, up to 2800 fathoms. A few species have invaded the fresh waters, while the pulmonate and terrestrial Gastropods are distributed over the whole surface of the land in all latitudes and to a height of 15,000 ft.

He also described a method of correcting deviation by means of a bar of vertical iron so placed as to correct the deviation nearly in all latitudes.

He attained correct views as to the character of centrifugal force in connexion with Galileo's theory; and, when the fact of the variation of gravity (Galileo's acceleration) in different latitudes first became known from the results of pendulum experiments, he at once perceived the possibility of connecting such a variation with the fact of the earth's diurnal rotation relatively to the stars.

In the colder latitudes, and even in the middle states, it is absolutely necessary to protect cauliflower in this way, as it is much more tender than cabbage and lettuce plants.

The darkest and best come from Labrador and Hudson Bay, and the ordinary sorts from the northwest of the United States and, as with silver and other kinds, the quality is inferior when taken from warmer latitudes.

Cold deserts accordingly occur in high latitudes such as in polar regions.

Where the line of elevated land runs east and west, as in Asia, the desert belt tends to be displaced into higher latitudes, and where the line runs north and south, as in Africa, America and Australia, the desert zone is cut through on the windward side of the elevation and the arid conditions intensified on the lee side.

It was formerly supposed that comparatively temperate latitudes and steep sloping ground afforded the most favourable situations for planting, and much of the disaster which attended the early stages of the tea enterprise in India is traceable to this erroneous conception.

The clay belt is in latitudes south of Winnipeg, with a good summer climate but cold winters.

Isochasms. - Aurora is seldom observed in low latitudes.

In the southern hemisphere there is comparatively little inhabited land in high latitudes and observational data are few; thus little is known as to how the frequency varies with latitude and longitude.

In other words, auroras are much more numerous in the southern parts of Canada and in the United States than in the same latitudes of Europe.

In high latitudes for several months in summer it is never dark, and consequently a total absence of visible aurora is practically inevitable.

Whether there is any real difference between high and mean latitudes in the annual frequency of the causes rendered visible by aurora, it is difficult to say.

It is only during winter and in high latitudes that we can hope to ascertain anything directly as to the real diurnal variation of the causes whose influence is visible at night as aurora.

The same phenomenon appears at Jan Mayen especially in November, December and January, and it is the normal state of matters in temperate latitudes, where the frequency is usually greatest between 8 and io P.M.

In temperate latitudes auroral arcs are seldom near the zenith, and there is reason to believe them at very great heights.

Relations to Magnetic Storms. - That there is an intimate connexion between aurora when visible in temperate latitudes and terrestrial magnetism is hardly open to doubt.

In high latitudes, however, where both auroras and magnetic storms are most numerous, the connexion between them is much less uniform.

In higher latitudes auroras are most often seen in the south.

None of the results so obtained can be accepted without reserve, but there are several reasons for believing that the average height in Greenland is much below that in lower latitudes.

The southern winds of-the summer months which occur in the low latitudes north of the equator are not felt much north of Khartum.

While the laminated portion of the thallus is being gradually worn off in our latitudes during the autumnal storms, a vigorous new growth appears at the junction of the stipe and the blade, as the result of which a new piece is added to the stipe and the lamina entirely renovated.

Pytheas certainly had one merit which distinguished him from almost all his contemporaries - he was a good astronomer, and was one of the first who made observations for the determination of latitudes, among others that of his native place Massilia, which he fixed with remarkable accuracy; his result, which was within a few miles of the truth, was adopted by Ptolemy, and became the basis of the Ptolemaic map of the western Mediterranean.

His detection of considerable errors in the tables then in use led him to the conclusion that a more accurate ascertainment of the places of the fixed stars was indispensable to the progress of astronomy; and, finding that Flamsteed and Hevelius had already undertaken to catalogue those visible in northern latitudes, he assumed to himself the task of making observations in the southern hemisphere.

Its original use was the determination of geographical latitudes in the field work of geodetic operations; more recently it has been extensively employed for the determination S of variation of latitude, at fixed stations, under the auspices of the International Geodetic Bureau, and for the astronomical determination of the constant of aberration.

Hence that climatic characteristic of the entire Pacific Coast - already referred to and which is of extreme importance in determining the life-zones of California - the great amount of total annual heat supply at comparatively high latitudes.

On the west coast the climate is moderate, but the influence of the cold north winds is felt as far south as Smyrna, and the winter at that place is colder than in corresponding latitudes in Europe.

Beneath the Rete, in a hollow, are four thin brass discs, called Tables or Climates, engraved with projections of the sphere for different latitudes.
