quantities of minary water emitted in each of the cases from March 2 to March 10, with 
the treadwheel and with light labour.

Chloride of Sodium. 
The elimination of chloride of sodium was commonly less on treadwheel than on the 
other days, but the difference was not very considerable. On the average of all the 
observations during the first ten days, the quantity of chloride of sodium evolved daily 
was 509 grs. with treadwheel, and 520 grs. with light labour. After that period the 
chloride of sodium was temporarily withheld ; but upon the average of all the observa- 
tions throughout the inquiry, the amount of that salt emitted was slightly less on tread- 
wheel than on other days, the actual quantities being 432 grs. and 437 grs. There was 
much variation in the results both on the same and on different prisoners. 
Fasces. 
The analyses of the foeces were made by Mr. Manning, from March 2 to March 16 
inclusive, including two Sundays, six treadwheel, and six liglit-labour days. There was 
no instance in this part of the inquiry of the evacuation being of a purged character. 
Nos. 858 and 1040 had only one day without an evacuation, and No. 948 had an evacua- 
tion daily ; but No. 1041 in but one instance had more than one evacuation every second 
day. The analysis on each day was made from the evacuation of that day ; and therefore 
on every alternate day there was no ftecal analysis in the case of No. 1041. In deter- 
mining the amount of the nitrogen emitted by the feces daily, I have been compelled to 
admit a small error by dividing the quantity of feces evacuated by No. 1041, on each occa- 
sion, equally between that and the preceding day, and to adopt a similar plan on the two 
exceptional occasions just mentioned in reference to the other prisoners. This prevents 
the accurate determination of the amount of nitrogen evolved by No. 1041 on any par- 
ticular day, as, for example, on the treadwheel days, and so far lessens the characteristic 
results of each day, on the average of the whole cases. I have also referred the feces 
to the preceding day, as they are clearly connected with the food of that day. 
The following Table gives the total daily weight of the fresh feces, with the total 
day emissions of nitrogen, and the amount of water, nitrogen, and ash in each ounce of 
the fresh feces.
