tins, into which they just fit, being prevented from moving by 

 layers of asbestos cardboard (A and B) above and below (Fig. 5). 



For larger samples the simple and efficient 

 apparatus (Fig. 6) described by Delepine may be 

 used. It consists of a metal case containing a 7 

 or i8 oz. bottle and a milk-scoop. All the parts 

 are thoroughly sterilised in the laboratory before 

 being sent out, and the sterilised case is only 

 opened at the time when the sample is taken. 

 The sterilised scoop is used to remove the milk 

 from the cans or other vessels. When obtained direct from

 cannot be examined within an hour or two, they must be 

 packed in ice. The ice box figured (Fig. 6), used by Dele-

 bacteriological samples of water, is very convenient. The
