 safely averred that the ideal sealing for milk bottles 

 is yet a thing of the future. The porcelain stopper

 Many do not close hermetically, the tension of the 

 wires being unequal, stronger on one side than on 

 the other ; no acid being admissible in the cleansing 

 of these bottles on account of its liability to corrode 

 the wire, they are with difficulty kept clean, the

 bottles, and the one which principally makes them 

 unfit to be utilized in the manufacture and dispensing 

 of food for .infants, is that neither the manufacturer 

 nor the buying public are able, by the outward ap- 

 pearance of the bottle or fastening, to detect if the 

 elfcct has -been complete, or if it even has
