title: A new form of automatic watering system for laboratory animals.
abstract: During a 2 1/2 year trial of this new system no algal or bacterial build-up occurred, and filters were changed only at infrequent intervals. Among the labour-saving advantages of it is that cleaning of the system can be done when cage racks are changed, normally monthly.
