rarely be quickened, but it is usually slow and irregular. There is 
no fever. The respirations are accelerated and the patients dys- 
pnoeic, the bronchi being filled with mucus. Mental symptoms 
are also present, particularly giddiness with confusion of ideas and 
rarely hallucinations. All these symptoms may vary in their inten- 
sity, at some times the gastro-intestinal predominating and at other 
times the mental. In light cases, where small quantities of the 
poisonous fungi are consumed, only an excessive salivation or per- 
spiration may be noticed, with uneasiness and discomfort in the 
stomach and bowels, the symptoms subsiding spontaneously in a 
few hours. In the severe cases, the vomiting and diarrhoea may 
be so pronounced as to rid the alimentary canal of the offending 
material and the nervous symptoms then become the predominant 
ones. With large quantities of poison also the patients may show 
the nervous manifestations from the start, delirium, violent convul- 
sions, and loss of consciousness developing in rapid succession 
and the patients sinking into a coma from which they can be 
roused with difficulty if at all. Rarely, consciousness is retained 
till the end, the patients dying from a paralysis of respiration. 
Finally, in many cases, after the preliminary attack of vomiting 
and diarrhoea, the patients sink into a deep sleep from which they 
wake several hours later profoundly prostrated but on the road to 
recovery. In such cases the effect of the poisoning passes off 
rapidly, the patients being restored to normal health within two 
or three days. There are no late effects or after-effects in 
Amanita muscaria intoxication, and the prognosis is always good 
if the patients recover from the preliminary symptoms. Chronic 
lesions such as develop in Amanita phalloides intoxication and are 
to be referred to the degenerative changes in the internal organs, 
do not occur with Amanita muscaria , 27 Rarely, the nervous 
manifestations of “ muscaria ” intoxication become much more 
pronounced than the alimentary and the patients become the vic- 
tims of excitement and hallucinations evidencing many of the 
symptoms of alcoholic intoxication. This variety of poisoning is 
particularly common in Siberia where decoctions of Amanita mus- 
caria are employed to induce orgies of drunkenness in which the 
most disgusting practices are followed, according to Kennan . 28 
The physiological effect of the Siberian Amanita muscaria has
