THE LATEST IN SCIENTIFIC VENTILATION. Very rapid strides have been made during recent years in the development of ventilation sytsems in Great Britain. Quite the most ingenious installation for an assembly house is that which is being arranged in the new Council Chamber of the London County Council. Each member is supplied with a current of pure air at the proper temperature, the speed of the current being so adjusted that no feeling of draught is experienced. The stream emerges from the desk in front of the member and drifts over his head. At his feet there is a small electric heater which can be switched on if desired. Thus the system is designed to keep the members’ heads cool and their feet warm—a condition which is understood to be the exact opposite of what usually exists in representative bodies. Another unique ventilation equipment recently installed in London is at a large film studio. The frequent occurrence of fog and the still more frequent tendency to haze in the atmosphere causes great expense and delay in the taking of film pictures in London stud’os. In order to ensure continuous working an automatic system of warming and damping the atmosphere of the building was designed. All the air entering the studio is washed, filtered, and warmed; and the control is so arranged that whatever change of temperature or condition of the outside air takes place the inside air is altered in such a way that no fog is produced. The control is so delicate that even the switching on of one or two lamps in the studio meets with an immediate response by the automatic plant. An endeavour is now being made to remove from the incoming air various gases which are contained in a London fog. These gases have no effect on the photographs taken, but they cause headache and lassitude among the per-
