The average decrease from the Satuixlay to the Sunday was 10 '2 9 oz. 
2. Specific Gravity . — The specific gra\ity of the urine varied from 1016 to 102 7 '5, 
but there was singular uniformity in the general results. In the Tailors it was 1023’7 
and 1025, and in the Weavers 1024'37 and 1024'6, giving a total average of 1024-35 
in the Tailors and 1024-45 in the Weavers. 
Chloride of Sodium (p. 811). , 
The average quantity of chloride of sodium evolved wns 3-37 grs. per oz. in the 
Tailors, and 3-18 grs. peroz. in the Weavers, giving a daily emission of 138-8 grs. in 
the former, and 148-5 grs. in the latter. 
Fceces (p. 811). 
The general character of the feeces was homogeneous and moderately cohesive ; but 
on a few occasions tliere was variety in the consistence. In the 52 observations, 32 
exhibited fieces formed but soon subsiding, 7 Avell-formed, 1 scybalous, 2 soft, and 9 
of mixed characters ; and no one prisoner offered any very marked difference in those 
conditions. The trace of the bran of the bread w'as easily seen in the faeces. The average 
daily evacuation was 6-98 oz. in the Tailors, and 8-52 oz. in the Weavers, giving a total 
daily average of 7-75 oz. There were somewhat considerable daily variations; so that 
the maximum and minimum quantities were in the Tailors 11-41 oz. and 4-32 oz., and 
in the Weavers 14-42 oz. and 1-72 oz. ; but in no instance was there the omission of a 
daily evacuation. 
The quantity of nitrogen per cent, found by Mr. Manning by the volumetric method, 
varied from -71 gi-. to 1-16 gr. in the Tailors, and from ‘97 gr. to 1-35 gr. in the Weavers ; 
but the total average in the two classes was -93 gr. in the Tailors and 1-12 gr. in the 
Weavers, giring 1-025 gi’. on the whole. 
The total daily elimination of nitrogen by the feeces were found to be 27 '43 grs. in the 
Tailors, and 40-93 grs. in the Weavers. The variation in the amount of faeces on 
Sunday from that of other days -was not uniform in quantity, since it was less on Sunday 
than on week days in the Weavers, and was equal in the Tailors. 
Such is a summary statement of the results obtained in the inquiry on two classes of 
prisoners, one of which followed a sedentary and non-laborious occupation, whilst the
