the drainage area from which the river is fed. 

 The nitrates are a little higher than is usual in 

 May, but the free and albumenoid ammonias 

 compare very well with the results obtained 

 by the New Orleans City Sewerage and Water 

 Board. The silt varies very largely from 

 month to month, hence no reliable conclusion 

 can be drawn from any one analysis. This 

 silt was saved and will be subjected to a plant 

 food analysis at a later date. 



In conclusion, let me say that this analysis 

 has, to my mind, demonstrated the desirability 

 of a very complete and detailed chemical 

 study, month by month, of the Mississippi 

 River and its tributaries, and I should have 

 undertaken such a study personally had I not 

 learned that it was already planned for by 

 Mr. M. O. Leighton, in charge of the Division 

 of Hydro-economics, U. S. Geological Survey.

functions of a transplanted kidney. 



The state of the circulation and of the 

 secretion of a transplanted kidney has been 

 observed on an animal operated on in this 

 laboratory. A careful investigation of the 

 literature has revealed no mention of a similar 

 experiment having been performed hitherto. 



The kidney of a small-sized dog was extir- 

 pated and transplanted into the neck. The 

 renal artery was united to the carotid artery, 

 the renal vein to the external jugular vein and 

 the ureter to the oesophagus. Three days 

 after the operation the neck and the abdomen 

 were opened, in order to study the functions 

 of the transplanted kidney and to compare 

 them with the functions of the normal kidney. 

 The transplanted kidney was found adherent 

 to the muscles, and dissection was necessary 

 to free it. In size it was larger than the 

 normal kidney. Its hue was darker. To the 

 touch the consistency of its tissue was normal, 

 and the pulsations of its artery were as strong 

 as the pulsations of the artery of the normal 

 kidney. 



Here is the summary of this observation: 

 the circjjdation in the transplanted Tcidney was 

 slightly greater than in the normal kidney. 



as detected by the touch, copiousness of hem- 

 orrhage from incision in cortex, and pulse- 

 tracings. 



The secretion of urine by the transplanted 

 kidney was about five times more rapid than 

 by the normal one. The intravenous injec- 

 tion of sodium chloride solution caused no 

 change in the rate of secretion in the normal, 

 but markedly increased the rate of the secre- 

 tion in the transplanted organ. 



The composition of urine secreted by the 

 transplanted kidney differed somewhat from 

 that secreted by the normal one. The con- 

 stituents were similar, but the chlorides ap- 

 peared to be more abundant in the urine from 

 the transplanted kidney, while the organic 

 sulphates, pigments and urea were more 

 abundant in the urine from the normal organ.

THE UNIVERSITY OF FLORIDA. 



The state legislature of Florida during its 

 recent session, April 4 to June 2 of the present 

 year, enacted a measure, commonly known as 

 the ' Buckman Bill ' designed by its orig- 

 inators to consolidate and strengthen, and to 

 economize in the running expenses of the 

 educational system of the state. By the pro- 

 visions of the bill the entire system of higher 

 education, consisting of a state university, a 

 girls' college, and including the normal school 

 for colored students and the institute for the 

 deaf and blind, is under the management of a 

 single board of control of five members ap- 

 pointed by the governor from five sections of 

 the state. By the terms of the bill existing 

 state schools are abolished as follows: The 

 University of Florida, Lake City; Florida 

 State College, Tallahassee; Normal School, 

 DeFuniac Springs; East Florida Seminary, 

 Gainsville; South Florida College, Bar- 

 tow; Florida Agricultural Institute, Osceola 

 County; and the Normal and Industrial de- 

 partment maintained by the state in the St. 

 Petersburg Normal and Industrial School. 

 To replace these abolished institutions there 

 is created a University of the State of Florida
