For the purpose of observing the thermal death-point a special water-bath is necessary.

Note that temperature, after exposure to which no growth takes place up to the end of seven days 'incubation, = the thermal death-point.

Arrange a series of incubators at fixed temperatures, varying 5° C. and including temperatures between 5° C. and 50° C. (In the absence of a sufficient number of incubators utilise the water-bath employed in testing the thermal death-point of vegetative forms.) 3.

Dry -- Spores: The thermal death-point in this case is that ~temperature~ which with certainty kills the spores of the organism in question when present in a thin film after a time exposure of ~10 minutes~.

Bacillus pyocyaneus, thermal death-point 55°C., and Bacillus mesentericus vulgatus, thermal death-point 60°C. -- a pure cultivation of the latter may be obtained by heating the mixture in a water-bath to 58°

Control these experiments, but in this instance syphon off portions of the suspension at intervals of one-half to one minute during the five or ten minutes preceding the previously determined death-point.

Seven minutes more and he will pass the death-point.

A temperature above the maximum growing-point (105°-115° F.) and below the thermal death-point (130°-140° F.) will prevent further growth, and consequently fermentative action.
