the normal muscle and the one injected with Panaeolus infusion 
when compared with respect to the length of time the muscles 
were able to work before fatigue set in is shown in experiment 2 
(TABLE 4). Here the normal muscle worked for a period of 28.9

minutes, while the injected gastrocnemius worked only 5.31 
minutes. The total number of contractions was greater for the 
normal muscles than the injected ones and the greatest difference 
between them was observed in experiment No. 6 (TABLE 4). In 
all cases, without an exception, the amount of work done by the 
normal muscle was greater. These experiments show conclusively 
that the infusion of Panaeolus venenosus has a harmful effect on 
the working power of a muscle. 
ТНЕ EFFECTS OF PANAEOLUS INFUSIÓN ON BLOOD PRESSURE AND 
PULSE 
Infusions of Panaeolus venenosus and P. retirugis were injected 
into the venous circulation of a cat to determine the effect of the 
infusion of these fungi on the blood pressure and pulse. A large 
female cat (weight 1,550 gm.) was used. She was anaesthetized
