244 Barker.—A Fragrant ‘ My coderma 5 Yeast. 
EXPLANATION OF FIGURES IN PLATE XIII. 
Illustrating Mr. Barker’s paper on a My coderma Yeast. 
Fig. i. Photograph of colonies on a plate of laevulose-Mayer gelatine (nat. 
size). Darker colonies becoming moist through absorption of liquefied gelatine. 
Two months old. At ordinary temperatures. 
Fig. 2. Photograph of colonies on a plate of beer-wort gelatine (nat. size). 
Two months old. At ordinary temperatures. 
Fig. 3. Plate-colonies on beer-wort gelatine at ordinary temperatures. The 
gelatine had partially liquefied. A, B, c, D, E, F, successive stages as shown on 
a seven days’ plate, x 2. 
Fig. 4. Colony on beer-wort gelatine plate. Gelatine solid. One month old. 
At ordinary temperatures, x 4. 
Fig. 5. Beer-wort gelatine plate-colony at ordinary temperatures, showing 
mycelium formation. Two months old. x 4. 
Fig. 6. Colonies on saccharose-gelatine plate at ordinary temperatures. Three 
months old. A. Dot-like colony. B. Colony with partial mycelial development, 
c. Colony with well-developed mycelium, x 6. 
Fig. 7. Plate-colony on laevulose-Mayer gelatine at ordinary temperatures. 
One month old. A. As seen from above. B. Side view, x 6. 
Fig. 8. Fatty-looking plate-colony on laevulose-Mayer gelatine at ordinary 
temperatures. One month old. x 4. 
Fig. 9. Successive stages of cell-formation by budding from a single cell. 
A, at 1.45 p.m. b, at 2.55 p.m. c, at 4.20 p.m. D, at 5.30 p.m. E, at 7.30 p.m. 
From hanging-drop culture in beer-wort gelatine. Gelatine partially liquefied, 
thus accounting for changes in position of the cells. At 18*5°—19 0 C. x 1000. 
Fig. 10. Vegetation of secondary films (veils). A, on beer-wort. B, on sac- 
charose-Mayer solution. c, on laevulose-Mayer solution, x 480. 
Fig. 11. Stages in the germination of spores at I5°C. Group of four spores. 
A, at 3 p.m. B, at 9.45 a.m., three days later, c, at 11.15 a.m. D, at 2 p.m. 
E. at 4.35 p.m. f, at 9.30 p.m. Single spore: G, at 3 p.m. H, at 9.30 a.m., four 
days later. I, at 1.15 p.m. x 1000. 
Fig. 12. Portion of mycelium developed at edge of plate-colony on beer-wort 
gelatine (see Fig. 5). a. Terminal filament, b. Older branched portion, x 480.
