78 T Doulton's Germ-Proof Filters (Admiralty pattern). As will be seen from above section, 

 the method of attachment is of the simplest character, the Germ-Proof Tube being easily 

 removed for periodical sterilising by boiling. The niters are fitted with rings between 

 the outer case and the container or lining, and also between the container and lid, to 

 prevent vibration and breakage. , The cleaning instructions are printed and burnt on the 

 ware, thus avoiding the use of adhesive paper labels.
