The water enters at the bottomthrough thesmall tube,which stopsshort on theinside of theouter box. Thew a t e r thenflows under and aroundthe inner box, and event-ually reaches at thefarllierend the wide out-flow tube. The end ofthis is turned up and isprovided with a shortpiece of rubber moving this up ordown the level of thewater in the box can beregulated. By regulat-ing the flow of the water it is possible to maintain afairly constant temperature iu the inner compartment.
