of the rear centre building will contain store rooms and vegetable cellars.

PRINCIPAL STORY.

The general plan of the building consists of a centre building, three stories high, sixty feet by ninety-two feet, a building in the rear of the centre, two stories high, forty-nine feet by one hundred and fifty-six feet, and two wings of three sections each, two being three stories high. The first section on each side is fifty-six feet by one hundred and fiftyfour feet; the second section, fifty-six by one hundred and forty-five feet nine inches; the third section, two stories high, fifty-seven feet by one hundred and twenty-one feet nine inches; one being at each side of and at an angle of forty-five degrees to the second section. This gives eight distinct wards for each sex, the minimum required (by unanimous vote of the Association of Medical Superintendents of American Institutions for the Insane) in a hospital for two hundred patients; this designed for three hundred.

The principal story of the centre building contains Superintendent's room, twenty feet square; private room, seventeen feet by twenty feet; Assistant Superintendent's room, seventeen feet by twenty feet; apothecary's room, twelve feet by seventeen feet; library, twelve feet by seventeen feet; dining room, twenty feet by forty feet; pantry, seventeen feet by twenty feet; and six large closets.

The first section on each side of the centre will contain fifteen single rooms, eight feet six inches by fourteen feet; sitting room, twenty-two feet by thirty feet; bay window, eighteen feet by twenty feet; reception room, thirteen feet by twenty-one feet; attendants' room, thirteen feet by twenty-one feet; bath room, nine feet by fourteen feet; storeroom, nine feet by fourteen feet; dormitory, seventeen feet by twenty-seven feet; dining room, sixteen feet by thirty-four feet.

The second section on each side will contain sixteen single rooms; general store room, twenty feet by twenty-three feet; the other rooms are the same as described for first section.

The third section will contain twelve single rooms, eight feet six inches by fourteen feet; open corridor, twenty-eight feet by sixty-two feet; dining room, seventeen feet by twenty feet; storeroom, ten feet by seventeen feet; attendants' room, fourteen feet by seventeen feet; bath room, ten feet by seventeen feet.

SECOND STORY.

The second and third stories of the first and second sections are divided the same as the first story of said buildings, and the second story of the third section is also like the first story of the same. attics of the first and second sections will furnish pleasant and desirable The infirmaries. The attics of the third section will afford ample and convenient room for the isolation of small pox and other contagious diseases. ♦

The second and third stories of the centre building are arranged to accommodate the Superintendent and his family, with his assistants.

* The second story of the rear centre building contains a chapel, forty-five feet by seventy-five feet; domestics' room, fourteen feet by twenty feet; billiard room, eighteen feet by forty-five feet; storeroom, twelve feet by twenty feet. The main centre building and the first section on each side, also rear centre buildings, are connected by corridors ten feet wide.

Is located one hundred and three feet distant from the rear centre building, and is forty-seven feet by seventy-four feet, containing a boiler room thirteen feet by fifty-seven feet; engine room, fourteen feet by twenty-four feet; fan blower room, thirty-two feet by fourteen feet; fuel rooms, fourteen feet by twenty-three feet, and fourteen feet by thirty-four feet; connected with this house is the large chimney, fifteen feet square at the base by one hundred and eighty feet in height.

The outside cellar walls are to be two feet thick of stone laid in cement mortar; the walls above are of brick twenty inches thick, laid hollow, the outer walls being twelve inches, an air space of four inches, and the inner wall four inches thick. The interior walls on the side corridors will be also twenty inches thick, so as to leave room for the ventilating and heating flues to pass through them. To render the building as nearly fireproof as possible without going to the expense of brick arches and iron beams or girders, all the plastering will be done directly upon the brick walls without furring; the floors will be plastered between the floor boards and the base or plinth around the rooms, and corridors will be of face brick, painted; all the inside partitions will be also of brick.

To give some idea of the size of the building, it may be stated that it will require one thousand seven hundred and seventy-five perches of stone for the foundation. Seven million seven hundred and fifty thousand two hundred and fifty bricks will be used in the walls; sixty-two thousand eight hundred and twenty-nine yards of plastering; three thousand two hundred and twenty-four feet of gutters, with two thouBand twenty-two feet of conductors; eighteen thousand two hundred and fifty feet of gas pipe; one million two hundred and eighty-nine thousand four hundred and eighty-eight feet of lumber; one thousand two hundred and thirty-eight windows; fifty-nine thousand four hundred and twenty-four lights of glass, and nine hundred eighty-nine doors; five hundred and four being required for the pipe chambers in the base

ment.

The building will be arranged so as to hereafter decide upon the best method of heating, whether by hot water, high or low pressure steam, all of which systems have their strenuous advocates. The ventilation of all the waterclosets will be effected by the downward draft to the heated chimney; the ventilation of the wards will be likewise arranged for the downward draft; there will also be provided in the boiler house, a fan blower upon the Doctor Nichols plan, to be used as occasion may require.

342

The high chimney will be so constructed as to form a large ventilating flue entirely around the boiler flue, to assure a steady draft. The underground air flues will be eight feet in diameter, diminishing in size as they approach the third section, with small branches to each of the several hot air chambers in the basement story.

COUNTY OF SURREY ADDITIONAL LUNATIC ASYLUM.

At Brookwood, near Woking.

The additional asylum for the pauper lunatics of the County of Surrey is designed to accommodate six hundred and fifty patients, and stands on an estate of about one hundred and fifty acres in extent, at Brookwood, about three miles from the Woking station on the South Western Railway.

The site is bounded on the south by the Basingstoke Canal, and on the east and west by the high roads to Guildford and Chertsey. Few sites could be found in the country better adapted for such an institution. The soil, a primary consideration, is a dry sand, with occasional veins of gravel, loam, and clay. The ground rises gradually from the south and west about seventy feet above the level of the canal, and the buildings are erected on a plateau of some extent, with a fine range of views and southern aspect.

The plan of the building gives to every part uninterrupted views of the surrounding country, and free access to light and air.

The principal entrance with the visiting Justices', Superintendent's, Porter's, Steward's, and waiting rooms form the central portion of the north front of the main building.

To the west of the entrance block is the laundry wing, with the rooms for the female working patients and their attendants.

On the east side of the entrance block corresponding to the laundry wing just described, are the workshops and the apartments appropriated to the patients engaged in them.

In the centre are placed the kitchen, offices and stores, so arranged that the service on the male side is perfectly separated from the female side.

The apartments for the Assistant Surgeon and the matron, with dispensary and stores, are grouped together in the centre of the south building, near the wards for recent cases, which with the infirmaries form the rest of the south front of main building.

The height of the rooms occupied by the patients on the ground floor is twelve feet, and on the upper floors eleven feet.

Fifty superficial feet, or nearly six hundred cubic feet, are allowed to each patient in all dormitories, except those in the infirmaries, where the cubical contents exceed seven hundred feet per patient.

The smallest separate sleeping room is nine feet by seven feet, which gives seven hundred cubic feet; in the infirmaries they vary from eleven feet by eight feet seven inches to fourteen feet by ten feet.

The day rooms, except one on each side of the wards for recent and acute case, are all on the ground floor.
