of the patients, whom this last substance disagreed with, the 
pills of M. Vallet were easily digested, and their use was 
followed by marked amelioration. In all, the heart lost its 
tumultuous and irregular movement, and resumed its normal 
pulsations. The sound of the arteries ceased, as well as the 
throbbing of the head and the disposition to syncope, at the 
same time the capillary system became injected, and the lips 
resumed their vermilion color. These favorable modifications 
were suspended a long time in one of the patients whom we 
had bled. 
" The courses were restored in five of these patients, they 
had not yet been established in the one of fourteen years, and did 
not return in the one we had bled. 
" From one hundred to three hundred pills were adminis- 
tered to our patients, in from twelve days to a month, and 
were sufficient to produce an improvement or cure, as we 
have reported. 
" It is as well to remark here, that the most protracted 
treatment did not require more than three hundred pills, or a 
little more than three drachms of carbonate of iron, which 
furnished an evident proof of the good state of the iron in 
the pills, — since we are forced to administer much larger 
doses of other ferruginous preparations. 
" It results from our experience that the new preparation 
can be administered easily in the dose of ten pills daily; that 
this dose, which can be exceeded, suffices to produce the 
modification of the blood and of the economy which is 
desirable in chlorosis; that, so far from deranging the diges- 
tion, this preparation facilitates it, acts favorably upon 
menstruation, and the results which it affords, appear to be 
more readily obtained than from the greater number of other 
ferruginous preparations." 
Before concluding, we think it necessary to report two 
observations made by M. Vallet, since presenting his memoir, 
which are interesting in the medical history of chlorosis: 
"M. Vallet has found a little iron in the urine of females 
in health. He has found a much greater proportion in the
