Practical sanitation; a handbook for sanitary inspectors and others;with apxon Sanitary law, by Herbert Manley . ating tabloids of paraform. Eecently, how-ever, what appears to be a more efficient, and by no meanselaborate, apparatus has been introduced, called the Lingnerdisinfecting apparatus. The drawing, with a section of theworking parts (Fig. 106), represents this apparatus, which 214 PRACTICAL SANITATION. consists of a circular boiler, A, for generating steam, surroundinga reservoir, B, containing a 40 per cent, formic aldehyde solu-tion, or a special preparation called glycoformal (a mixtureof formic aldehyde, glycerine, and water). The working of theapparatus will be understood from the following description withthe aid of the sectional drawing. The heating medium is methyl-ated spirit with which asbestos, in the circular trough, 0, underthe boiler, is saturated, and the steam passes from the boiler intothe reservoir through connecting pipes, D, and forces the formicaldehyde, in a vaporised state, through four nozzles connectedwith tubes, E, into the room. Experiments with the apparatus. Fig. 106. have been conducted by Dr, Klein, who found that by a threehours exposure to formic aldehyde vapour discharged from it ina sealed up room virulent spores of Bacillus anthracis andvirulent tubercle bacilli were destroyed, and he states thatthe results compared most favourably with those previouslyobtained by him in conjunction with Drs. Houston and Gordonwith the Alformant lamp which are referred to later.* In place of using this substance in a gaseous form someadvocate its use in solution in the form of a spray. Dr. LeslieMackenzie strongly advocates this method of room highly efficient disinfection Dr. Kenwood recommends theuse of a spray containing 0-5 per cent, formic aldehyde followedby the fumigation process. As in the case of all fumigation processes, it is necessary toseal up the room openings, and the room should be kept closedfor six hou
