    media, and small for filtering staining solutions. A few quite small ones, about 3 cm. in. diameter, are also required for filtering the staining solution direct upon the cover-glass. 11. Small glass benches, with their ends bent over, upon which to stand cultures (Fig. 8). 12. Test tubes, of at least 15 mm. in diameter and 15 cm. in length. For anaerobic cultivations lono-er ones, and for EsmarcVs tubes wider ones are required. A considerable number of tubes are needed, and in procuring them it is unwise to be too economical. 13. Beakers. These are needed for various pur- poses; I myself use them for boiling the nutrient gelatine. It is also convenient to sterilise small glass tubes, pipettes, etc., in beakers in the hot-air sterilisiug apparatus. 14. A wash-bottle of about 250 grms. capacity, with a finely drawn out tube. 15. Two graduated measures for measuring out the quantity of water in preparing the nutrient media— one of 1 litre in capacity divided into ten parts, and another of ]00 cm. divided into twenty parts. 16. Measuring pipettes, several of 1 ccm. in capa- city divided into tenths, and others of 2, 5, 10, 20, 25, 50, and 100 ccm. capacity. 17. Glass dishes with double covers, for the so-called plate cultures, of about 10 cm. diameter; the lids should fit as well as possible.
