CYSTICERCUS CELLULOSUS.

but it was found necessary to keep the patient constantly 
under its influence for some hours, as much as six ounces of 
the agent having been used before the action of the poison 
had passed off. 
CONDITIONAL STATE OF CARBONATE OF LIME IN WATER. 
It is commonly stated that lime is held in solution in 
water, giving to it hardness, in the form of bicarbonate. 
Mr. E. J. Reynolds, however, avers that this compound does 
not exist, but what is so termed is merely a solution of 
carbonate of lime in carbonic acid—CaO C0 2 in C0 2 . He 
adds there are many instances of an acid favouring the solu¬ 
tion of a substance that is insoluble, or nearly so. Further, 
“ there is no instance in chemistry of a bicarbonate being so 
loosely constituted as to lose one equivalent of its acid by 
mere exposure to the air. Even magnesia, which is known 
to exist as a bicarbonate, both in solution and in the solid 
state, loses only one fourth of its carbonic acid, and is 
deposited as a sesquicarbonate.” 
THE CYSTICERCUS CELLULOSUS TRANSFORMED WITHIN 
THE ORGANISM OF MAN INTO THE TJENIA SOLIUM. 
It will be remembered that* M. Ktichenmeister, a very 
patient experimentalist, endeavoured to prove this transfor¬ 
mation first upon animals and subsequently upon a human 
being. In the latter case, the cysticercus, concealed in food, 
was given to a woman lying under sentence of death, 72, 60, 
36, 24, and 12 hours before execution, when four young 
taeniae were found in the duodenum, and six more in the 
remainder of the intestinal canal. Experiments were also 
made, some time back, by a young man under the observa¬ 
tion of M. Leuckart, and by M. Humbert, when fragments 
were discharged two or three months afterwards. But doubts 
might be raised respecting all these experiments, especially 
as to the previous existence of any ova within the intestinal 
canal. M. Kiichenmeister, however, had an opportunity, to¬ 
wards the latter end of 1859, as stated by the Duetsche Klinik , 
of renewing the experiment in conjunction with Dr. Sieben- 
haar. The first injection of cysticerci took place November 
24th, 1859, and the second on the 18th of January, I860. The 
prisoner was decapitated on the 31st of March, and at the 
autopsy it was found that half the cysticerci that had been
