ved also by my own experiments, is but on oidium form of the 
same plant, which gives origin to penicillium crustaceum. If so, 
what limit can be set to the morbid capabilities of ‘the commonest 
species of fungus? Their capacity for mischief must be as varied 
as the conditions of their development. So pliable are these low 
forms of vegetable life, that their injurious influence upon the hu- 
man system, and upon the animal organism, need not be sought 
in their specific character, but may be ascribed to a virulence 
acquired by the circumstances, conditions, direction and depree of 
their development. This fact has received ample illustration by 
the rescarches of Prof. Hallier upon the fungi attendant upon 
the exanthemata *). 
In the hottest period of summer, when the liver is excited to 
an unusual activity, cases presenting many of the features of the 
Texas disease in cattle are not infrequent in man. They present 
the same fatty degeneration and box-wood discoloration of the liver, 
the hemorrhages into the stomach and intestines, albumenuria and 
fatty degeneration of the kidneys, intense jaundice, yellow gru- 
mous, but usually scanty biliary secretion, high fever, softening 
of the spleen; all these characteristics without the suspicion of 
yellow fever infection. In some of these cases disorder of the 
liver is the only recognizable cause of a train of symptoms ending 
in black vomit and death; in others, Bright’s disease of the 
kidneys is the basis upon which these symptoms are engrafted. 
In these cases and in yellow fever, an acute cholaemia or admix- 
ture of bile with the blood is the most decided of all the patho- 
logical phenomena. The group of symptoms and: lesions in the 
Texas disease is therefore well established, and corresponds to 
the action of a not unusual combination of causes, as well as to 
that of the yellow fever miasm. The application of the term yellow 
fever to the Texas disease of cattle, is warranted both by its pa- 
thological characteristics, and by the source of the contagion. From 
examination of the liver of yellow fever, I am confident that the 
same injection of the biliary radicles would be found as in the

*) Auf die Abweichung in den Ansichten brauche ich die Leser dieser Zeit- 
schrift kaum besonders aufmerksam zu machen. Nach meiner Ueberzeugung 
ist es gerade die specifische Natur des Pilzes, der die verderbliche Hefe liefert, 
welche die Natur der nachtheiligen Wirkung auf den Organismus bedingt.
