and Chanson had similar experiences. The latter two observers, 
working with an ascaris from the horse, suffered in addition 
from pain in the throat and loss of voice. These experimenters 
found that two cubic centimeters of the fluid taken from the 
inside of these worms would kill a rabbit. 
Kolbe, of Reinez, after having read Peiper’s publication, 
above referred to, reported a remarkable case of a child he had 
unsuccessfully treated with the regular worm medicines. The 
boy had suffered for-over a year from severe abdominal pains, 
frequent attacks of fainting, and convulsions. The doctor hav- 
ing been unsuccessful, a friend of the boy’s mother — a baker 
by trade — suggested that she should rub up a dried round- 
worm with sugar, and make the boy take it. This “ homceo- 
pathic ” remedy had an immediate effect ; two tangled masses 
of worms the size of a fist being given off by the patient, who 
made a prompt and complete recovery. Cobbold and Davaine 
have reported cases where various nervous symptoms had sub- 
sided on the removal of tapeworms. Marx saw an epilepsy of 
three years’ standing cease on the removal of a Tenia solium. 
It is curious that the eyes are so frequently affected in those 
suffering from tapeworms. It is quite possible that this is due 
to the effects of a poison circulating in the blood, the same 
having been absorbed from the intestine where the parasite is 
domiciled. In five out of fourteen cases of patients harboring 
the tapeworm known as Tænia nana, Grassi observed serious 
symptoms resembling those of epilepsy. 
Another worm, the Bothriocephalus, may cause severe anz- 
mia, which has variously been explained as due to a peculiar 
poison, to effects resulting from the death of the worm, or to the 
length of time that the individual has harbored the parasite. 
A blood-sucking worm, the Anchylostoma, which may occur in 
hundreds and even thousands in the intestine, was believed by 
Lussana to contain a poison, and not to injure its host simply 
through the loss of blood it entailed. Looss, of Cairo, also 
states his belief, in a recent publication, that these parasites con- 
tain a poison. Working with the larve of this worm last sum- 
mer, he found that even after carefully washing them, they. 
caused dogs which had swallowed them to vomit, whereas the
