In the year 1851, F. Kiichenmeister first proved by experiment cn : 
perma hydatid when brought into a suitable place, is developed into 
tapeworm. He fed a dog with the hydatids i aca visiformt) 
found in the mcg wae of the hare, and on dissecting the dog, afters 
number of weeks, found these Cysticerci alive in mn the small westine, 
They had, melt lost “eet il-bladder, and the neck had begun to 
Jorm the joints of a true ee gniettn which worm had been long well 
know Tenia serrata, and as common in the dog. Now, one dit 
covery followed another. ‘entionionts: scientific institutions, and wealthy 
armers furnished the money and animals to carry on the experiments on 
a large scale. Siebold fed a dog with the Hchinococcus of the ox, and 
thus raised the Tenia Echinococcus, Siebold. It was also found in the 
same way that the Cenurus from the brain of sheep is the larve 
another Tenia of the dog, Tenia Caenurus, Siebold. 
Now sa question, whence does man get ‘his tapeworm? was — to 
answered. It had been observed that the hydatids of the hog 
monly called “ measles” (in the zoological system, Cysticercus Celle) 
have exactly the same head as the common tapeworm of man qT 
Solium, L.); and after the experiments mentioned above, in relation 19 to 
the different tapeworms of dogs, a doubt could — = apo’ 
(Tenia Solium). Kichenm —— who wished to mak ‘sh tee “a 
as tapeworms in his intestine, and in different stages 0 
according to the intervals in which the siaiiles had pris taken. hich 
Thus it became clear, that all hydatids are tapewo m larves, ire
