corpuscle of human blood. d is introduced as a good example of the produc- 
tion by such filamentous plants of substantial conidia having the characters of 
the cells of Toruwla Ovalis, while in ¢ we have a plant which in some parts is 
as delicate as 6, while in others it looks as if composed of elongated cells of 
the torula. Other obviously transitional forms, between the filamentous 
fungus and the torula, are represented by the groups e, f, and gy. Compar- 
ing the appearances of the organism as it occurred in the two glasses, the 
cellular element predominated over the filamentous in the PasreEur’s solution, 
while the converse was the case in the urine. The toruloid groups, rare in the 
latter liquid, were abundant in the former, in which also the filamentous 
plants were as a rule of a coarser character, and were invariably small; that is 
to say, not extending to any great length, as they did in the other medium. 
The granules of the filaments and the nuclei of the cells were also much more 
marked in the PastEur’s solution. Along with this deficiency of the filamentous 
element, the bacteric form was absent in the PAsTEur’s solution. Some of the 
buds were indeed as slender as the bacteria of the urine, as is illustrated by 
the plants 6 and ¢, and here and there such buds were seen floating free in pairs 
such as h, but no bacteric movement was to be seen. This puzzled me at the 
time; but I afterwards found that it was no reason for surprise, and I shall 
hereafter have occasion to mention cases of bacteria of ordinary form and 
active movement in urine, assuming a motionless character and at the same 
time a very different appearance in other media. 
Although the proof already afforded of the identity of the Torula Ovalis with 
the filamentous fungus may appear sufficiently ample, yet, as the point is of 
extreme interest, I have been well pleased to obtain further confirmation of the 
fact while preparing this communication for the press. On the 9th November 
1873 I once more removed the test-tube containing the Pasrrur’s solution from 
its cotton packing to see what change it might have undergone. I found about 
half of the original volume of the liquid still remaining unevaporated. It was still 
transparent, but it was now of a pale brownish yellow colour, and the sediment 
had a similar tint. A delicate incrustation existed on the interior of the glass, 
but did not reach up to the level of the liquid, and the gelatinous lumps had 
disappeared from the dried part above. Raising the test tube cover with care- 
ful antiseptic precautions, I removed a few drops, taking up at the same time a 
little of the crust, which I detached from the side with the “heated ” pipette; 
and, after inoculating a glass of PAsTEuR’s solution with about half a minim, I 
proceeded to investigate the remainder. Under the microscope the solid con- 
stituent proved to be composed in the main of granular masses, looking like 
confused aggregations of the organism in an effete and degenerate state ; but 
projecting from the edges of these masses were plants and corpuscles, which, 
from their translucent and fresh appearance, made me hope that they were alive.
