Some of the conditions which tend to check the growth of bacteria werelearned from the milk experiment performed at home. A laboratory demonstra-tion developed this subject still further. One of the boys described the experi-ment thus: Sterilization. Mr. Peabody took three test tubes and inoculated someof the bacteria from the hay infusion. The first test tube contained nourishmentin a solid form (nutrient gelatin), and after the bacteria had been inoculated itwas set aside. The second test tube was prepared the same way, but Mr. Pea-body poured some corrosive sublimate over the surface of the gelatin. Thethird test tube was prepared in the same way as the first, but was put in the(steam) sterilizer for five minutes, and then set aside. and Laboratory Methods. 11()9 /^?ri /•. ^—?? f ? , u u -^^^T-i-^n.^/^ ^-^^/y^-^-ti^. ?<^<^2^CC&<^. -i^-ti^^Z^^^ Fig. .S.
