Potato. At 34 0 no growth. At 25 0 a yellow, thin, diffuse 
watery patch is formed in two or three days ; this remains 
pale — hardly visible as more than wetness in places — and in 
a week has scarcely spread. 
At 22° the growth was thicker and eventually more orange 
and wax-like : in a week it resembled the corresponding 
growth of No. 7, but more ochre-yellow in hue, spread, and 
bright like wet gum. 
Broth at 25 0 C. Slightly turbid in forty-eight hours. In 
a week hardly turbid, but an abundant flocculent yellowish- 
white deposit has fallen. On the ninth day there is a floccu- 
lent incomplete veil, and falling flocks. In a month the 
floating veil is easily shaken down, and the greyer colour of 
the deposit distinguishes it from No. 7. 
No growth at 35 0 , but at 18 0 it is as good as at 25 0 . 
The old cultures turn the broth sherry-colour, but the 
deposit remains greyish-ochre, not orange as in No. 7. 
Milk at 25 0 C. No change observed for three weeks, when 
the reaction was acid. In a month there are doubtful traces 
of clotting, but no true separation occurs. 
Glucose at 25°C. No results. 
Not pathogenic to guinea-pigs according to Dr. Kanthack’s 
report. 
No. 23 was revived in June from an agar-culture thirteen 
months old, which had remained quiescent from May 23 to 
June 24 of the following year. It came up on the plates very 
white and rapidly liquefied on the fourth day at 20°. The 
spider-like zoogloea-masses, characteristic fringed edges, and 
flame-like films on the surface of the gelatine suggested the 
type, and further cultures confirmed its identity, including the 
yellow colour. 
The 5 tab -ad tares gave a thistle-head funnel, very slowly 
liquefying at 20°, but in all other respects to type. 
Streak-cultures , side by side with the stab, gave rapidly 
scooping streaks, and in five days an abundant ochre growth 
and deposit formed in the liquefying gelatine. 
On agar and potato the cultures were normal ; except that
