Milk pasteurising plants and processes

so distinguished as President. Nor need there be fear that the more material side of the work of the Society-the aims to further the interests of the public health and those engaged in its service-will suffer during the period of Dr. Savage's tenure of office. It is not only in the laboratory and as a scientific investigator that he has attained fame and distinction. He is known, and the works he has performed and the contributions he has made on the practical side have shown him, to be no less skilled and experienced in the health field and as an administrator. He is qualified, therefore, and concerned as well, to fill the part a President must play on the business side of the Society: to advise and guide in the conduct of its affairs no less wisely and helpfully in Council, and with no less of dignity and success, than he will preside at Society meetings and act as the representative of the Society on formal and official occasions. If the Society is sure of this, there is a thing of which Dr. Savage in turn may be assured; that no matter the capacity in which he acts or appears, always and everywhere all the members are unanimous in their loyalty to him; accept him unhesitatingly as their head, and will never fail to render him at all times all respect and service.

absolutely essential if the treatment is to be effective are not always secured. The reasons for failure in these connections are to be found in imperfections in design or construction in the plant or in improper operation or control of the appliances and methods. As is well known, all milk sold under the designation " Pasteurised " is required to have Been treated in the manner prescribed in Part IV of the Third Schedule to the Milk (Special Designations) Order, 1923, i.e., it must be retained at a temperature of not less than 1450 and not more than 1500 Fahrenheit for at least half-an-hour, and be immediately cooled to a temperature of not more than 55° Fahrenheit. These requirements can be met with certainty only by what is known as " positive holding" (or the " holder method ") by which the whole of the milk is retained or " held" at the required pasteurising tempera~ ture for the specified time. The report shows, as indeed medical officers have found, that easy as it appears to be to secure compliance with requirements, failures are many, largely on account of imperfection in plant or technique. The report, which bears evidence of full and careful investigation and of having been prepared by one fully informed on the subject, has for its purpose the supplying of information on the subject of pasteurising plants, the explaining of considerations involved in their construction, operation and cleaning, and the giving of some account of the appliances and methods employed in the subsidiary processes of bottle-washing and bottle-filling. Since one of the conditions subject to which licences for selling milk as "Pasteurised" may be granted is that the type of apparatus used for pasteurising and the methods employed shall be such as are satisfactory to the local authority as licensing body, it is essential that they, and more particularly medical officers of health and other officers engaged in the work of supervision, should be well informed with regard to plants and processes. In these connections the report will certainly prove of material assistance, and so far as officers are concerned is likely to become more or less of a vade mecum. Because it has been so very well designed to serve this purpose, the report deserves something more than ordinary in the shape of recognition, and its author particular congratulation on the success he has undoubtedly achieved in providing such very clear descrip~ tions of matters liable to be found difficult to understand from mere written explanations.
