The sword shaped tails, at variance with the common theory, can be accounted for by supposing a slight difference in density or material in the cometic atmosphere, which will deflect the light as seen.
This is in accordance with the theory, the temperature named being that of the maximum density of water, and it confirms the recent observations of Prof.
If the density is too great there is an escape of hydrogen, and the metal is deposited in a spongy condition.

We have seen that the molecular weight of a compound, as well as of most elements, is obtained from the vapor density by doubling the latter.
If, then, the standard of vapor density is the H atom, half the molecular weight of a gas must be its vapor density, since it is evident that we thus compare the weights of equal volumes.
The vapor density of this compound shows that its symbol should be As4O6, but the improper one, As2O3, is likely to remain in use.
Compare the vapor densityof I with that of Br and of Cl.
Also, the vapor density is directly proportional to the pressure, since a liter of any gas under a pressure of one atmosphere is reduced to half a liter under two atmospheres.

The exposure necessary will depend upon the density and character of the negative.
The requisites of a perfect plate are, great sensitiveness, combined with extreme latitude in time of exposure, and density in development.
These directions apply to all dry plates except the Stanley, which can be developed to any required density at sight, and loses none in the fixing solution.
The time of exposure will vary according to the density of the negative and the intensity of the light.
Time is necessary in this process to secure enough intensity, and this stage is the most difficult in the process, there being no means by which to judge with any degree of certainty the density of the image before you.
The mode of the refraction depends on the comparativedensity or rarity of the respective media.

Is there any possibility of gainsaying the conclusions these facts force upon us; namely that the fecundity of marriages is regulated by the density of the population, and inversely to it?
He proposes to prove that the fecundity of marriages varies in inverse proportion to the density of the population.
It is, therefore, perfectly clear that the fecundity does not diminish whenever the density of the population increases.
All this the young fireman did with considerable energy and haste, because the density of the smoke was increasing, and his retreat might be cut off by the flames at any moment.

Those bodies that have in themselves the earthy nature, attract the light, not by virtue of an hidden quality, but out of the antagonism with the sun; now it may proceed either from greater density or from true basic import.
The density also is not the only determinant, but the quality also of the matter; the Basic or Planetary must refract more than the Oxygenic or Solar.
The sun appears to have only the density of water; for it is four times less dense than the earth, and is thus pretty nearly in the condition of water.
Materiality is not the only determinant of refraction, but also the density of the element, the earth refracting light more than water, and this more than air.
The most transparent bodies must also become with a greaterdensity adiaphanous or opaque, because the Metallic increases in them.
Were the earth larger, it must also have occupied some other place, and have had another velocity, another density of mass, &c.
It is matter properly at the first manifestation of being, of time and of space; for at the same instant also the line, surface, density and gravity have been given.
It is a well-known property of the air that the temperature diminishes with its height, a circumstance referable to the general physical law, that as the density of gases decreases they acquire an increased capacity for heat.
In the North Pacific the maximum density occurs between 30 deg.
In regard to the density of the water at various depths, it has been ascertained that as a general rule it decreases from the surface down to about 1,000 fathoms, after which it increases again slowly to the bottom.
In the vicinity of Java and Sumatra, probably on account of the extreme humidity of the atmosphere and of frequent rainfall, the densityhas been found as low as 1.
The density of the waters of the Indian Ocean is not yet as well known as that of the Atlantic and Pacific, but the results ascertained indicate a lesser density in its northern part, with a maximum in the region between 20 deg.
In the equatorial calm region the frequent rainfall diminishes salinity and density through the dilution of the salt water.
Van Bezold has put forth a memoir on thermodynamics, while Helmholtz, Oberbeck, and Diro-Kitso have contributed valuable memoirs on motions caused by gravitation and the varying densityof the air.
Density and salinity are thus in a certain degree subject to seasonal changes.
In the South Pacific, which has a slightly greater density than the North Pacific, the maximum has been found in the vicinity of the Society Islands.
The salinity and density of sea water have been investigated very thoroughly, particularly in the Atlantic.
In the Atlantic the density increases in general from the higher latitudes towards the equator, but the maxima are separated by a zone of lesser density.
Density considered, in other words, the western roads are all as well kept up as those in the East.
This was due, of course, to the notable concentration of train loading, already described, as well as to a density of traffic per mile of line almost sixty per cent.
Density increasing in this way, a corresponding ability to carry at a lower rate per ton was a necessary result.
The most important single factor in the production of increasing returns upon a railroad is the density of traffic; that is to say, the amount of business which can be conducted with a given set of rails, terminals and rolling stock.
How closely this will approximate the facts in any particular instance will depend upon the density of traffic attained in relation to the capacity of the existing plant.
Fortunate the lot of the railroad which enjoys both these advantages, of density of traffic per mile of line and of tonnage capable of such concentration in heavy train units.
The high density of trunk line traffic is such that about two-thirds of all the tonnage of the United States is transported east of the Mississippi and north of the Ohio river.
The soft coal Hocking Valley road with its enormous density and very low revenue per ton mile, affords an excellent example.
A comparison of the rates of growth of mileage and traffic, or of density of traffic, shows how new construction is lagging behind the development of business.

At 2400 hours it was Vincennes Check with the density reports, all down in the past hour.
As we ascend from the galactic plane we perceive that the density decreases with great rapidity.
Here, too, we find different degrees of solidity or density in the agglomerated matter.
It is evident that the density of bodies must be diminished by expansion; and in the case of fluids and gases, the parts of which are mobile, many important phenomena depend upon this circumstance.
We see matter existing in space partly in the form of rotating and revolving spheroids, differing greatly in density and magnitude, and partly in the form of self-luminous vapour dispersed in shining nebulous spots or patches.
Yet again, the atmosphere diminishes in density upwards, and this diminution will affect the transmission of the electric force.

But the only fact in favour of such an hypothesis is the close correspondence between the apparent density of these planets and that of water.
Strong lines mark increased density in the absorbent medium, and lines hitherto unobserved indicate new elements.
Another inference is that the density of the planet must exceed the ordinary estimate in the proportion of two to one.
If equal masses are taken, the value of the constant R for different gases varies inversely as the molecular weight or as the density relative to hydrogen.
