Sexual excitement is one among many causes intellectual excitement, pain, a loud noise, even any sensory irritation which produce dilatation of the pupils and enlargement of the palpebral fissure, with some protrusion of the eyeball. The influence of the sexual system upon the eye appears to be far less potent in men than in women.

This dilatation, however, is not effected by continuous application of combustibles, but by a peculiar process of transfer, by which the caloric is made to operate over and over again namely, the heat of the air escaping from the working cylinder at each successive stroke of the engine, is transferred to the cold compressed air, entering the same; so that, in fact, a continued application of fuel is only necessary in order to make good the losses of heat occasioned by the unavoidable eradiation of the heated parts of the machine.

In general, their cohesion is greatly increased, and the dilatation produced by slight changes of temperature is considerable. Sir James Dewar has effected careful measurements of the dilatation of certain bodies at low temperatures: for example, of ice. Changes in colour occur, and vermilion and iodide of mercury pass into pale orange.

Tenderness on pressure over the bone is the most valuable diagnostic sign. At a later stage there is an ill-defined swelling in the region of the ossifying junction, with œdema of the overlying skin and dilatation of the superficial veins. The swelling appears earlier and is more definite in superficial bones such as the tibia, than in those more deeply placed such as the upper end of the femur.

This table should have on it a wash-basin, a hand-brush, soap and hot water, an antiseptic solution, scissors, a ligature for the navel, and a suitable aseptic lubricant for the hands. The Process of Labor. The process of labor is divided into three stages. The first stage is that of dilatation; by which is meant the stretching of the mouth of the womb so that the child may pass through.

Stimulation of this centre causes contraction of the blood-vessels. Severing the same part causes paralysis of the vaso-motor nerves and dilatation of the blood-vessels. The conditions of the brain that have been most clearly shown to influence the circulation, are those that can be proved to take an effect on this vaso-motor centre.

We next crossed a dilatation of the river, about six miles in length, upon which the name of Lake Prosperous was bestowed. Its shores, though scantily supplied with wood, are very picturesque.

At a pressure of 0.0055 mm., 0.066 millionth, the highest exhaust obtained in any of the experiments, even a one-inch spark from an induction coil refused to pass. It was also ascertained that there is neither condensacian nor dilatation of the gas in contact with the terminals prior to the passage of the discharge.

The symptoms produced by the latter are usually vomiting, abdominal pain, pains in the limbs and cramps, diarrhoea, vertigo, coldness, faintness, and collapse. The symptoms of botulism are dryness of skin and mucous membranes, dilatation of pupils, paralysis of muscles, diplopia, etc.
