3. Ethyl chloride jet.
6. Sterile glass capsules of various sizes.
7. Cases of sterile pipettes { 10 c.c. (in tenths of a cubic centimetre).
{ 1 c.c. (in hundredths of a cubic
centimetre).
8. Flasks (75 c.c.) containing sterilised normal saline solution (or
sterile bouillon).
9. Sterilised cotton-wool. Cotton-wool (absorbent) is packed loosely in
a copper cylinder similar to that used for storing capsules, and
sterilised in the hot-air oven.
10. Sterilised gauze. Gauze is sterilised in the same way as
cotton-wool.

preferably carried out, the day previous to the operation.
~Material Utilised for Inoculation.~--The material inoculated may be
either--
1. Cultures of bacteria--grown in fluid media, or on solid media.
2. Metabolic products of bacterial activity--e. g., toxins in
solution.
3. Pathological products (fluid secretions an
