276 Prof. V. Harley. Influence of Removal of Large Intestine and 



gravity varying from 1016 to 1042. In spite of the great fluctuation 

 in the quantity of water, the quantity of nitrogen daily eliminated in 

 the urine varied only from 4*815 to 4-120 grams, so that there was no- 

 great difference per diem. 



The quantity of fseces which were passed daily varied from 56*70 

 to 97-82 grams, and the nitrogen contained in the fseces fluctuated from 

 0'907 to 1*383 grams. The fat in the fseces during the eighth, ninth.,, 

 and tenth days varied from 0*548 to 0*777 gram, while on the eleventh 

 day, from some unknown reason, in spite of the fseces not having 

 increased markedly in quantity, the quantity of fat contained therein 

 was 1'041 grams. The absorption of nitrogen, in consequence of the- 

 varied quantities passed on the different days, fluctuated somewhat 

 considerably, consequently another period of analysis was done on 

 exactly the same diet for another period of four days, the diet in the- 

 interval having been kept the same. 



(b) In this second stage of the experiment a part of the urine was; 

 unfortunately lost on the eighteenth day. The daily quantity varied' 

 from 309 to 395 c.c., with a specific gravity of 1012 to 1018. That is 

 to say, the quantity was very much increased above that found during 

 the previous four days, and the specific gravity very much lower. The* 

 quantity of nitrogen in the urine during these three days varied from 

 4-290 to 4-427 grams, so that that factor tallied very much with that 

 found on the previous day. 



The daily quantities of fseces were also more equal than on the 

 previous four days, as they varied from 68*67 to 81-12 grams, the- 

 nitrogen varying from 1*258 to 0*987 gram; the daily fat in this case 

 being fairly equal, and showing no marked rise as in the preceding 

 period, varying from 0'713toO*513 gram. 



(c) During the next (the third) period the quantity of fat was in- 

 creased to 29*71 grams on the nineteenth day; and the analysis began 

 on the twenty-second. The weight went up from 4*11 to 4*17 kilos. 

 The quantity of urine passed fluctuated from 121 to 265 c.c., with a 

 specific gravity varying from 1014 to 1029. The nitrogen in the urine* 

 decreased in amount, fluctuating from 3*010 to 3*344 grams. The- 

 quantities of fseces .observed daily were . very nearly equal, varying 

 from 82*56 to 84*82 grams, the nitrogen in the fseces remaining very 

 constant, the fluctuations being only between 1*005 and 1*162 grams,, 

 and the fat also remained very constant, varying from 0*699 to 0*850 

 gram. 



(d) In the final period (the fourth), the food being in the interval 

 kept exactly the same, the animal went up somewhat in weight, rising 

 to 4*31 kilos. The quantity of urine passed varied from 52 to 240 

 c.c. ; but the small quantity of urine passed on the twenty-ninth day 

 is in all probability an error, as the specific gravity on that occasion 

 was practically the same as on other days. Leaving this day's amount
