The materials for Pasteur's solution and Sach's nutrient solution can best be obtained from a druggist at the time needed and in very small and accurately measured quantities. The agar or gelatine cultures in Petri dishes may be obtained from the local Board of Health or from any good druggist. These cultures are not difficult to make, but take a number of hours' consecutive work, often difficult for the average teacher to obtain. Full directions how to prepare these cultures will be found in Hunter's _Laboratory Problems in Civic Biology_. INDEX (Illustrations are indicated by page numerals in bold-faced type.)
