It has simply been traced as far as the formation of a diblastula which acquires a ciliated band, and becomes a nearly spherical trochosphere.
Passing on, we find not far from the genital pore a glandular spherical body (the spermatheca c) opening by means of a longish duct into the common duct, and then we reach the pore (fig.
A trial was then made at 350 yards; the spherical balls and the conical balls both went home to the target, but only one of the latter penetrated.

I might go on to elaborate this method, to show how it may be made still more exact, but as it will come under the discussion of spherical surfaces, I will leave it for the present.
To measure a plane or curved surface with this instrument, a perfect plane or perfect spherical surface of known radius must be used to determine the zero point of the division.
Unfortunately for this process, it demands a large truly spherical surface, which is just as difficult of attainment as any form of regular surface.

When such a disk is dried in the sun, and the bristles entirely removed, the lines of suture of the plates composing it, and corresponding exactly to those of the spherical Sea-urchin, may very readily be seen.
The disk is so flat, being but very slightly convex on the upper side, that one would certainly not associate it at first sight with the common spherical Sea-urchin or Sea-egg, as the Toxopneustes is sometimes called.
When it first escapes from the parent Hydroid stock, the Oceania is almost spherical in form.
As the animal advances in age the disk loses its spherical outline, and becomes much flattened, as may be seen in Fig.
After a day or two the outline of these planulae, spherical at first, becomes pear-shaped (see Fig.
A cubical or spherical mass of cells could not grow by the formation of new layers of cells on the outside, for these layers would deprive the centrally placed masses of cells of their conditions of existence.
The attempt to become spherical is opposed by other forces, in accordance with which the cells resulting from division press against each other.
I have only mentioned spherical spots for distinctness sake; but this discharging operation is found diversifying those strata in various ways, but always referable to the same or similar causes.
This, by gravitation, is reduced to a spherical form, and by the centrifugal force of the earth's rotation, is become oblate.
The flattening of the spherical earth was not suspected until in 1672 a clock regulated to beat seconds at Paris, when taken to Cayenne near the equator was found to lose two and one-half minutes a day.
The probability of cloth entering a wound with the conical ball is not so great as it was with the spherical ball, which not unfrequently tore out a little cap, as it were, of cloth in its passage.
Both these injuries, however, were caused by spherical balls.
Then there appeared, I knew not how, but seemingly developed by the same agency and in the same manner as the crystals, a small transparent sphere within the watery globe, containing itself a spherical nucleus.
Therefore, it was evident to him that the heaven was of a spherical figure.
Hayy concludes that the Heaven is of a spherical Figure.
In spite of the development of the dirigible airship, there remains work for the free, spherical type of balloon in the scientific field.
In Reptilia the eye is spherical and its anterior part is often protected by bony plates in the sclerotic (Lacertilia and Chelonia).
In fishes the eyeball is flattened in front, but the flat cornea is compensated by a spherical lens, which, unlike that of other vertebrates, is adapted for near vision when at rest.
Again, he never tells us whether he believed the earth to be flat or spherical; he uses at one time language that belongs to the spherical earth, and at another, language that can have sense only if he believed the earth to be flat.
The ocean is on the surface of this spherical earth, and it washes “the limits of the circle of lands”.
He entirely omits the sentence in which Hyginus passes from the subject of the spherical earth to that of the lands.
In the passage from Hyginus, terra in the singular is the sphericalearth occupying the centre of the sphere formed by the universe.
He states the theory of the zones correctly in two passages,[59] applying it, however, not to the spherical earth but to the sphere of the heavens.
As he moved imperceptibly closer to her, he saw the two priests beside the gray mechanism reaching toward knurled knobs of ebonite affixed to its side, beneath the spherical web of pulsing wires.
Two of them stood beside a cubical, weird-looking gray metal mechanism from which upreared a spherical web of countless fine wires, unthinkably intricate in their network, many of them pulsing with glowing force.
The sphericalweb of wires pulsed up madly with shining force.
We may form an idea of this, by supposing a vessel filled with small spherical leaden bullets, into which a quantity of fine sand is poured, which, insinuating into the intervals between the bullets, will fill up every void.
The rectilinear path of a Spherical Body influenced by its rotatory motion.
The game of bilboquet, or cup and ball, will show the influence of rotatory motion in steadying the rectilinear path of a spherical body, whence the theory of the rifle-gun may be deduced.
A person with a spherical head seldom lived beyond middle age.
A spherical head denoted inconstancy, forgetfulness, and want of discretion.
The Huygenean conceives it to consist in the undulations of a highly elastic and subtle fluid, propagated round luminous centres in spherical waves, like those arising in a placid lake when a stone is dropped into the water.
He showed the properties of spherical segments and methods for calculating surface areas and other parts of spherical forms.
He defined spherical triangles and arranged methods for determining the volumes of irregular solids by measuring the water displaced by them.
Each of these spherical bodies rotates; that is to say, turns round and round, as a top does when it is spinning.
The Greek philosophers, who busied themselves much with such matters, gradually became convinced that the earth was spherical in shape, that is to say, round like a ball.
The earth is, therefore, what is technically known as an oblate spheroid; that is, a body of spherical shape flattened at the poles.
Half the length of the projection is equal to the mean spherical intensity to the same scale as the original polar curve.
Their arithmetical mean is the mean spherical intensity.
Owing to the absence of an integrating photometer, the mean spherical candle power has been found by Kennelley’s graphical method.
This method is very simple as compared with Rousseau’s and has the advantage of yielding the mean spherical intensity as a one dimensional quantity.
The sphericalreduction factor for these lamps is, then 9.
He now called me to see his buoyancy gauge, which was a half-spherical mass of steel weighing just ten pounds.
If an opaque body and a luminous one are (both) spherical the base of the pyramid of rays will bear the same proportion to the luminous body as the base of the pyramid of shade to the opaque body.
A perfectly spherical body surrounded by light and shade will appear to have one side larger than the other in proportion as one is more highly lighted than the other.
If a spherical solid body is illuminated by a light of elongated form the shadow produced by the longest portion of this light will have less defined outlines than that which is produced by the breadth of the same light.
The farther a sphericalbody is from the eye the more you will see of it.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "spherical" in a variety of sentences. We hope that you will now be able to make sentences using this word.
