Milk for Infants.
The recent hot weather (says a writer in the Australasian) has emphasised the necessity for an improvement in the means o* suoplyinf. the inhabitants of cities with pure milk in a condition suitable for human consumption. The problem is not solved by making laws piohibiting the addition to milk of ary preserving substance. During hot weather a very large quantity ot miVi turns =our, and becomes unsaleable, even when the precaution of cooling it down immediately after milking is observed While milk is a highly valuable articie of food and indispensable for infants, it must be F* rff4ctlv fresh and •-*««* when used, othervrist- serious trouble may be caused. The trend of opinion in Europe in connection with the milk supply of cities seems to be in the direction of sterilisation. At the International Dairy Congress, held in Paris, special attention was devoted to processes for the preservation of milk. M. Michel, a farmer, of Tomblaine-Nancy, deserlfeeJ a- process of sterilisation with -whjcii he ha r l obtained excellent results. He had beei entrusted with the sterilisation of milk dhiribu*- by the medical pjacti-
tioners-.of Nancy, with a view of- checking' the mortality amongst the children of tho poor. After experiments t M. .Miche, finally adopted > the ';ffollowing" prpcess:—"The bottles are closed by means _ a tin cr.pmile, provided -at the top' with a^imaJljp^himngr-JikcsJ; aperture, -Q&vhioh is^aeHj :flWen oSjHng first Dwrfc of tffe *Sfeiilisfng process.
