Up to the seventh month the pupil is closed by the membrana pupillaris, derived from the capsule of the lens which is part of the mesodermal ingrowth through the choroidal fissure already mentioned.
The posterior part of the eyeball and the anterior parts of the muscles are enveloped in a lymph space, known as the capsule of Tenon, which assists their movements.
In these cases, as well as in all cases of plastic iritis which have not been properly treated, serious consequences to sight are apt to follow from the binding down of the iris to the lens capsule and the occlusion of the pupil by exudation.
Often an eye bears permanent traces of a perforation in adhesion of the iris to the back of a corneal scar or in changes in the lens capsule (capsular cataract).
According to the nature and severity of the exudation there may be deposits formed on the back of the cornea, attachments between the iris and lens capsule (synechiae), or even gelatinous-looking coagulations or pus in the anterior chamber.
Penetrating wounds of the eye involving the capsule, or rupture of the capsule from severe blows on the eye without perforation of its coats, are followed by rapidly developing cataract.
The farther it is moved outwards, the greater is the pressure upon the thermostatic capsule and consequently the higher will be the boiling point of its contained liquid.
The temperature at which it is desired that the liquid in the capsule shall boil can be determined by sliding the weight (W) nearer or farther to the fulcrum of the lever (L').
The thermostatic capsule is placed on a fixed cradle (F) and is filled with a mixture of ether and alcohol, the proportions being such that the boiling point of the mixed liquid is 100 deg.
This thermostatic capsule works admirably, and the incubator will work for months at a time and requires no adjustment, however much, within the limits of our climate, the external temperature may vary.
The principle upon which this capsule is designed is that the boiling point of a liquid depends not only upon temperature but also upon pressure.
The distension of this capsule can be used to raise the lever (L').
The heat-regulating apparatus is identical with that in the chick incubator, and the thermostatic capsule (S) is placed in the upper chamber, near the head of the infant.
When the capsule is thoroughly ripened by the sun, it bursts, and expels the seeds, which are usually three in number.
The sole effect of mingling two kinds of pollen is to produce in the same capsule seeds which yield plants, some taking after the one and some after the other parent.
Mr. Scott likewise fertilised fifty-four flowers of Verbascum phoeniceum, including two varieties, with their own pollen, and not a single capsule was produced.
With hybrids raised from the same seed-capsule the degree of sterility is innately variable, so it is in a marked manner with illegitimate plants.
The innate sterility of hybrids of the same parentage and raised from the same seed-capsule often differs much in degree.
After evaporation the capsule is weighed, which shows the yield of the bark in aqueous extract.
Put the product in a porcelain capsule and expose it to the heat of a boiling water bath for half an hour, with occasional stirring.
The chemical toy sold under this name consists of the powder of sulphocyanide of mercury made up in a capsule of tin foil in a conical mass of about an inch in height.
Transfer the contents of the retort to a porcelain capsule and evaporate the liquid until it is reduced to 4 fl.
A few days after the petals have fallen the capsule is ready for incision.
If the capsuleis too dense to allow the worm to be seen, a drop or two of weak hydrochloric acid should be added.
The cells are surrounded by a dense capsule of connective substance, and in some cases the peripheral zone of the cell next the capsule is light.
These spots are provided with a lens, connective tissue capsule and a reflector, and are supposed to be luminous.
Head-capsule compact, massive, the praefrons large with a few marginal punctures; externo-lateral plates very broad.
On examining the eye by looking straight into it through the pupil, the anterior wall of the capsuleappeared opaque in its whole extent, and of a color and luster like mother-of-pearl.
On looking from the temporal side in an oblique direction into the pupil, there was visible in the anterior wall of the capsule a very small perpendicular cleft of about one line and a quarter in length.
On the other hand, it seems probable that the lateral cleft in the capsule permitted rays of light to pass into the interior of the eye.
They all have some form of a capsule for fruit, which in most generally split lengthwise.
In the coco de mer, a palm from the Seychelles, the seed often weighs forty or fifty pounds, while in some orchids a single capsule will contain over a million almost microscopic seeds.
The fruits are practically always a capsule that splits lengthwise.
A three-celled capsulesplitting lengthwise as in the common Iris.
DOSE: One capsule four to six times daily, Followed by large glass of water.
A solution of the entire capsule content was deep blue and responded to the U.
It is the most important thing of all--you can get along with it alone if you lose everything else, but without that capsule the whole system's shot to pieces.
No missile this, but a capsule containing a full ton of allotropic iron, which would be of more use to the Nevian defenders than millions of men.
Take this capsule and hide it against your skin, some place where it can't be found except by the most rigid search.
C: Depth from a point in front of capsule for incisor (See C to C' on Fig.
Relative to the length of the ramus (measured from the anterior mental foramen to the posterior margin of the capsule that surrounds the root of the lower incisor), the depth of the ramus anterior to the molariform tooth-row is 33.
Each consists of a globular capsule pierced at one or two points for the entrance of nerves which end in a central cup-shaped "striated body.
The fruit or capsule is obtusely three-cornered, and about the size of a hazel-nut; it contains three cells each enclosing a seed.
A capsule of carbon filled with mercury, which formed the positive electrode of the electric lamp, has a carbon point brought down upon it.
Placing in front of the electric lamp the intense flame of a large Bunsen's burner, a platinum capsule containing a bit of sodium less than a pea in magnitude is plunged into the flame.
Brush these particles into a capsule of pure water.
This question primarily hinges on whether the corneo-sclera is to be regarded as an unelastic capsule with a fixed volume, or as a yielding envelope with an ever changing capacity.
The great ganglia were of relatively large dimension, and the white mass of the hemisphere, aside from the internal capsule and the other detachments mediating the connection of the cortex with lower centres, relatively reduced.
The projecting fibres, such as those of crus and capsule and the great ganglia, are not as massive as in man, but they are nearly equal to, and in still lower forms exceed, those connecting the gyri with each other.
We were not able to observe this particular sub-peduncle any longer; but it would certainly have gone on circumnutating until the capsule was nearly ripe (which requires only a short time), and it would then have moved upwards.
The tracing was not continued any longer; but after two additional days, the peduncle with its capsule had become straight and stood upright.
In order to trace this upward movement, a filament was fixed to a sub-peduncle bearing a capsule nearly ripe, which was beginning to bend upwards by the two means just described.
By its subsequent upward movement, the capsule stands when ripe at a greater height above the ground by twice the length of the sub-peduncle, than it did when dependent, and is thus able to scatter its seeds to a greater distance.
Even the position of a seed at the end of the capsule sometimes gives to the seedling developed from it a tendency to revert.
The missile lies in the joint capsule between the head of the tibia, in front of the spine, and the patellar notch of the femur.
The course of the bullet was transverse, entering the capsule posterior to the patella without injury to the bone.
For convenience sake I chiefly tried small seeds, without the capsule or fruit; and as all of these sank in a few days, they could not be floated across wide spaces of the sea, whether or not they were injured by the salt-water.
So it is with hybrids, for their degree of fertility is often found to differ greatly in the several individuals raised from seed out of the same capsule and exposed to exactly the same conditions.
After several weeks thecapsule was removed, the bacilli found still alive, and transferred to another capsule in another fowl.
The collodion capsule permitted the fluids of the body to enter and provide food for the bacilli, but prevented the admission of the leucocytes to attack and destroy them.
It was further pointed out that there had been no opportunity of giving the boy a pill without the knowledge of the schoolmaster, and that the prisoner could not have charged the capsule with aconitine without having been observed.
He points out that Lamson was far too clever a man to attempt such a clumsy plan as to charge the capsule with aconitine, and thus draw suspicion upon himself.
Then he took a capsule from his pocket, gulped it down with some water, and sat back down.
Presently the capsule was shifted automatically into the pressure tube that would carry him thirty miles north to his destination.
The orderly brought a glass of water and a small capsule which Black Doctor Tanner gulped down.
