I suspect some native German speakers should be consulted about what it says or doesn’t say.

“p.227 b) totaler Erwärmung ”
describes several experiments run where temperature was raised from 21-23,5 to 38-39 degree Celsius with a living frog inside
In most cases it was observed that the frog has reached “Wämestarre”, the opposite of “Kältestarre” (I don’t know the english translation – maybe burmation?)
In any case the frog seems to be rigid, although I am not sure if it really died

p228 / Versuch XII / experiment 12 looks promising: heated to 39°C without reaction (and prior experiments in the same paper already established that around 37.5°C is sufficient for it to be unable to move), and the animal wasn’t fixated in some way but simply placed on submerged moss as a bedding (prior experiments either affixed the frog with a hook or string)
Versuch XIII / experiment 13: heated to 38.5°C, then frog moved its front part that wasn’t submerged up to then; but it couldn’t move it’s hindlegs that were submerged and already in “Wärmestarre”
following experiments all had same results without problems; closing paragraph:
“Von einer gewissen Temperatur an scheint das Thier gleich dem Erfrierenden in einen schlafähnlichen Zustand zu fallen, der dann, wenn er einmal eingetreten, eine etwas schnellere Temperaturerhöhung gestattet.” – from a certain temperature onwards, similar to a freezing one, the animal appears to fall into a sleep-like state, which then permits slightly faster heating from that point onwards.
The last experiments were run at approx. 1/350° per second, but crossing the threshold of 1/200° per second always resulted in failure.
