Special interest wasconnected with these observations not onlyas illustrating the growth of spores, or germs;but as allowing application of the test of heatat different stages of growth. When this testwas applied, it was found that one hundredand forty degrees Fahr. was sufficient to causethe death of adults, whereas the young sporeswere able to live notwithstanding the applicationof three hundred degrees Fahr. for tenminutes. In this direction fresh discoverywas to be made.In June 1877,-a month later,-ProfessorTyndall gave the record of further researches.*These presented additional results as to degreesof temperature requisite for destroyinglnicroscopic organisms. It had been alreadyshown that alkaline liquids are more difficultto sterilize, than acid liquids; it was further* Ndure vol. xvi. p. 127.
