A treatise on hospital and asylum construction; with special reference to pavilion wards . onmechauical ventilation, that the fan is stopped onlyten minutes each day for oiling.

The fresh warm air is admitted at 4 registers(B), placed in the floor to save expense in the con-struction which was kept at minimum. The vitiated air is removed by four fire-places(D), in the center of the \vard. The four ceiling registers (C), are not dependedupon to any extent, although fresh cold air may beadmitted through them in winter, and heated airemitted in summer, thus preventing areas of stag-nation. All registers may be operated from thefloor of the ward. The warm air is passed oversteam coils, placed below each floor register, each ofwhich has an independent supply of fresh cold airalso controlled from the ward. The ward contains about 12,530 cubic feet of air,and 12 cribs for children are provided, thus allowingeach 1,044 cubic feet: it should be borne in mind. ooa c3 P-l -^ U Pi 122 HOSPITAL AND ASYLUM COXSTRUCTIOX. that children and old people give off less carbonicanhydride tlian others. {Parkcs.^ The size of each fresh -warm air register is 14X 21, or a total gross area 1176 square inches andan estimated available net area of 74S square anemometer showed (testing each) an averagecorrected incoming velocity of 15S lineal feet perminute or a total supply of S59 cubic feet per min-ute for the ward.
