874 INFLUENCE OF FOOD PRESERVATIVES ON HEALTH. 



No. 7 shows a few casts in the fore period; they are numerous in 

 the first part of the preservative period, and fairly numerous in the 

 second part of the preservative period. During the other periods 

 No. 7 is not under observation. 



No. 8 has a few casts in the fore and after periods, and in the second 

 and third parts of the preservative periods, and they are fairly 

 numerous in the first part of the preservative period. 



No. 9 has a few casts in the fore period, and the second part of the 

 preservative period and the latter part of the after period; they are 

 fairly numerous at the first and third observations in the preservative 

 period. 



No. 10 shows a few casts in the fore period and the first part of the 

 preservative period, very few in the second observation of the preserv- 

 ative period, fairly numerous at the third observation, and very few 

 in the after period. 



No. 11' exhibits a few casts in the fore period and the first and third 

 parts of the preservative period; numerous casts are recorded in the 

 second part of the preservative period, and they are fairly numerous 

 in the after period. 



No. 12 shows a few casts in the fore period and the first and second 

 parts of the preservative period, and very few in the other periods. 

 Judging by the figures obtained to express the relative occurrence of 

 these bodies in the urine, there is a slight tendency to an increase 

 during the preservative period. 



For purposes of comparison an expression is obtained, as explained 

 in Bulletin 84, Part II, page 575, showing the general summary of the 

 occurrence of these bodies in the aggregate in the urine for the entire 

 period of observation. In the fore period the number is 54.5 as 

 representing the relative occurrence of all the bodies; in the preserv- 

 ative period 66.7, and in the after period 65.5, showing a tendency 

 to increase the occurrence of these bodies, which is continued in the 

 after period.
