The difficulty may be overcome by using, instead of a thermometer, a pyrometer, actuated by a metal rod extending across the interior of the chamber. 12. In steam apparatus the three requirements above mentioned are all satisfactorily met, and for this reason, as well as on account of greater rapidity and certainty of action of steam, steam chambers are in his opinion greatly preferable to those in which dry heat is em- ployed. 13. It is important that the arrangements of the ap- paratus, the method of working, and the mode of con- veyance to and fro should be such as to obviate risk of articles which have been submitted to disinfection com- ing into contact with others which are infected. There are several steam disinfecting machines in the market, notably, Bradford's, Washington Lyon's, and Goddard, Massey and Warner's. The Nottingham steam disinfecting apparatus, as shown in fig. 45, which is that manufactured by Messrs. Goddard, Massey and Warner, of Nottingham, is undoubtedly much superior to any other steam disinfecting machine invented. The makers claim for the Nottingham steam disin- fecting apparatus the following advantages :— 1. Its simplicity—a labourer can work it after a few trials. 2. It is entirely self contained, generating its own steam, and heating the air required. 3. Condensation on the sides is impossible because they form part of the boiler. 4. Condensation on the end doors is also impossible
