DE. SMITH ON THE ELIMINATION 
Ui'ea (p. 809). 
The analysis for urea was made by Liebig’s method in the manner already described in 
reference to the experiments at Coldbath Fields. 
The total average daily quantity of urea evolved was 655’65grs., of which 608‘4grs. 
were emitted by the Tailors, and 702’9 grs. by the Weavers. ' The maximum and mini- 
mum amounts were 790 grs. and456gTS., — the former in the Weavers, and the latter in 
the Tailors. In the Weavers the quantity exceeded 700 grains on seven of thirteen 
days, whilst it occurred only three times during that period in the Tailors ; and in only 
one instance during the inquiry was it below 500 grs. daily. 
The quantity of urea to each pound of body-weight (p.. 810) was 4; 812 grs. in the 
Tailors, and 4' 6 75 grs. in the Weavers ; but it varied in the former from 3 ’72 grs. to 
5‘82 grs., and in the latter from 3'62 grs. to 5’39 grs. on different days. The quantity 
of urea eliminated was always lessened on the Sunday (pp. 809, 812). The diminution 
in the Tailors from the Saturday to the Sunday was 145 grs. and 122 grs., and in the 
Weavers 26 grs. and 92 grs., yielding an average diminution of 96'25grs. 
The quantity of urea in each ounce of urine was on the average 14-9 grs. in the Tailors, 
and 15'25 grs. in the Weavers, giving a total average of 16'075 grs. The maximum and 
minimum quantities were 18’8gTS. and 12‘3grs. in the Tailors, and 17'84gTS. and 13'53 
grs. in the Weavers. 
Weight of Body (p. 810). 
The average weight of three of the prisoners during the inquiry was greater than that 
recorded on the day preceding the commencement of the inquiry ; but there was a loss 
of weight of the fourth. The average gain of the Tailors was 15-|-oz. and 17f oz., and 
of one of the Weavers 3^ oz., but the other Weaver lost 3f oz. The greatest gain in the 
different cases was 1 lb. 13:^ oz. and 1 lb. 7^ oz. in the Tailors, and 8f oz. and 1 lb. 11 oz. 
in the Weavers ; and the greatest loss was \\ oz. in one Tailor, and 1 lb. oz. and 4|- oz. 
in the Weavers. There was not any unvarying progression in the weight during the 
week; but in every case there was an increase from the Saturday to the Sunday, and 
the amount was as follows: ll^^oz. and lO^joz., 9^oz. and 5 oz. in the Tailors; 6:jOz. 
and 18^ oz., 19|-oz. and 31|-oz. in the Weavers, or an average increase on the Sunday 
of 13’62 oz. 
TJrine (p. 810). 
1. (Quantity . — The largest quantity of urine evolved in one day was 25,321 grs. 
(56-6 oz.) and26,624grs. (59T7oz.) in the Tailors, 27,791 grs. (62-3 oz.) and 32,924 grs. 
(74 oz.) in the Weavers. The average daily quantity was 41-2 oz. in the Tailors, and 
47-51 oz. in the Weavers, giving a total daily average of 44-35 oz. There was a large 
increase on the Saturday^ and, a-marked. decrease on. the Sunday, as the following quan- 
tities prove.
