In Finland the death-rate at the earlier period taken for the comparison was abnormally swollen by epidemic disease, and if it be set on one side the decline appears to have been in harmony with that in its Scandinavian neighbours.
A common type of mirage is the appearance of an isolated lake frequently seen in hot sandy deserts, as in the Sahara, Turkestan, &c. The explanation is as follows: The sand, being abnormally heated by the solar rays, causes the neighbouring air to expand, consequently its density, and therefore its refractive index, is diminished, and attains a minimum value in the lowest layers.
In her childhood she was noted for her abounding physical energy; but her vivacity, so far from being tainted by any coarse or unfeminine trait, was the direct outcome of an abnormally sensitive nervous temperament.
Absorbed in the work of the foreign office, which at this time was abnormally active, he refrained from pressing home the arguments for internal reform.
In the case of those oils which do not belong to the rape oils and yet show abnormally low saponification values, the suspicion is raised at once that a certain amount of mineral oils (which do not absorb alkali and are therefore termed "unsaponifiable") has been admixed fraudulently.
The portion of the lachrymal duct communicating with the cavity of the nose has, on the other hand, been abnormally developed, apparently for the purpose of cleansing that chamber from particles of sand which may obtain an entrance while the animal is burrowing.
Taking the statistics for the whole kingdom, the annual marriagerate for the years 1876-1880 was 7.53 per 100o; in 1881-1885 it rose to 8o6; in 1886-1890 it was 777; in 1891-1895 it was 7.41, and in 1896-1900 it had gone down to 7.14 (a figure largely produced by the abnormally low rate of 6.88 in 1898), and in 1902 was 7.23.
576 1254 The most significant item in the table, 36 passengers killed in train accidents, is perhaps to be considered as abnormally large, the totals under this head for the preceding six years beginning with 1901 being 7, 35, 3, 18, 4, 14, or an average of 11.57 per year.
When the Civil War was over, the abnormally high price of cotton made cotton raising for more than a decade a great assistance to the people in recovering from ruin, but when the price had steadily declined from 23.98 cents a pound in 1870 to 10.38 cents a pound in 1879, they turned to the erection and operation of cotton mills.
Hence it is that the amount of food consumed to produce a given amount of increase in live weight, as well as that required for the sustentation of a given live weight for a given time, should - provided the food be not abnormally deficient in nitrogenous substance - be characteristically dependent on its supplies of digestible and available non-nitrogenous constituents.
Hence, as current fattening food-stuffs go - assuming, of course, that they are not abnormally low in the nitrogenous constituents - they are, as foods, more valuable in proportion to their richness in digestible and available nonnitrogenous than to that of their nitrogenous constituents.
Strisores, a group now separated from the Clamatores of Wagner, and containing those forms which have their feet abnormally constructed; and 4.
MARSHBUCK, a book-name proposed for such of the African bushbucks or harnessed antelopes as have abnormally long hoofs to support them in walking on marshy or swampy ground.
By actual observations it has been shown that ether, alcohol, many esters of the normal alcohols and fatty acids, benzene, and its halogen substitution products, have critical constants agreeing with this originally empirical law, due to Sydney Young and Thomas; acetic acid behaves abnormally, pointing to associated molecules at the critical point.
The Anglo-Boer War (1899-1902) caused both revenue and expenditure to rise abnormally, while the depression in trade which followed the war adversely affected the exchequer.
There is no evidence to show that the Vincent who was sub-prior of this foundation in 1246 is the encyclopaedist; nor indeed is it likely that a man of such abnormally studious habits could have found time to attend to the daily business routine of a monastic establishment.
Such bodies show strong absorption bands in those colours which they reflect, while of the transmitted light that which is of a slightly greater wave-length than the absorbed light has an abnormally great refrangibility, and that of a slightly shorter wave-length an abnormally small refrangibility.
During the century which had elapsed since the expulsion of the Peisistratids and the establishment of the democracy, the Athenian constitution had developed with a rapidity which produced an oligarchical reaction, and the discussion of constitutional principles and precedents, always familiar to the citizen of Athens, was thus abnormally stimulated.
The miners were an energetic, covetous, wandering, abnormally excitable body of men.
In the opposite direction will be noted the case of Ireland, where the rate is abnormally low; and returns more recent than those included in the table show that of late the rates in Sweden and Norway have also fallen to but little above 11 per mille.
It is true that a Young Wales party has arisen, which seeks to narrow this movement to the exclusion of English ideas and influences; and it is also true that there is a party which is abnormally suspicious of and hostile to this Welsh Renaissance; but in the main it is correct to say that the bulk of the Welsh nation remains content to assert its views and requirements in a reasonable manner.
The climate is healthy and agreeable, though the death-rate among the common people is abnormally high on account of personal habits and unsanitary surroundings.
The heart's action is feeble, the pulse being small, irregular and often abnormally slow.
The Australasian species come nearest to laying eggs, inasmuch as the eggs are large, full of yolk, and enclosed in a shell; but development normally takes place in the uterus, though abnormally, incompletely developed eggs are extruded.
Now measurements of osmotic properties of these solutions show that their osmotic pressures are abnormally great and that, at extreme dilution, the ratio of their osmotic pressures to that of equivalent solutions of non-electrolytes is equal to the number of ions indicated by the electrolytic properties.
Formaldehyde behaves abnormally with magnesium benzyl bromide (M.
Travellers whose idea of picturesqueness is based upon the abnormally sharpened peaks of the ice-sculptured Alps are disappointed with the scenery of the central and southern ranges of the Rocky Mountains.
