There is, perhaps, a no more useful piece of apparatus in a general bacteri- ological laboratory than a suitable thermo-regulated water bath. The uses to which it may be advantageously put are so numerous that after the habit of using it is established it soon becomes almost indispensable. Wiesnegg antici- pated its value and placed upon the market his bain-marie which has met with unquestioned favor. However, its usefulness, on account of its form and size, is somewhat restricted. In order to extend the utility of the principle involved in this apparatus, I have had, by way of experiment, two water baths or tanks constructed and permanently fitted with thermostats and thermom- eters. They have been in use for nearly a year and have proven to be so satisfac- tory that a brief note concerning them may be of general interest. Their shape or size should not be taken into serious consideration, for they are flexible features which can easily be adapted to individual needs or requirements. The emphasis should be placed rather on the assistance they render in the saving of time and in the securing of uniform results. In laboratories where instruc- tion is given such assistance is much appreciated by both students and (60-65° C.) temperature for making cul- ture media. It can also be used for a variety of other purposes, such, for example, as sterilizing liquid blood serum or by a class of laboratory stu- dents in determining the approximate thermal death points of different bac- teria. It consists of a rectangular copper tank 45x50x25 centimeters. It is divided.
