Apparatus for Carrying Samples of Water for Bacteriological 
Examination.* — Dr. L. Heydenreich describes an apparatus used in the 
transport of samples of water. It is cylindrical, stands on short feet, 
and is provided with a lid and handle. From the lower edge projects a 
short nozzle for the outflow of melted ice-water. The bucket is made of 
metal, is lined with felt, and covered with oilcloth. Its internal arrange- 
ments are three superimposed frames or trays, the uppermost for ice, the 
lower two for bottles. Each tray will hold ten bottles. At the bottom 
of the upper tray is a short pipe, through which the melted ice escapes 
to the bottom. The free end of this pipe projects into the groove a 
(figs. 169, 170).

In fig. 171 is a pan or tray with details and measurements. The 
upright rods with pieces turned in at right angles support the tray 
above, and serve also for the removal of the tray itself. 
A description of another metal case for bottles requiring special care 
is also given (fig. 172). The chief points in this apparatus consist in
