868 INFLUENCE OF FOOD PRESERVATIVES ON HEALTH. 



In the case of No. 3 a very few crystals are found in the fore period, 

 the first test in the preservative period, and both observations of the 

 after period. 



For No. 4 there are a very few crystals found in the latter part of 

 the preservative period and in the first part of the after period. 



In the case of No. 5 there are no crystals observed except a very 

 few in the after period. 



In the case of No. 6 there are no crystals observed except in the first 

 part of the preservative period. 



No. 7 shows a very few crystals at the first and second tests in the 

 preservative periods. 



For No. 8 no crystals are observed except a very few in the after 

 period. 



In the case of No. 9 a very few are found in the last part of the pre- 

 servative period and also in the after period. 



For No. 10 a very few crystals are reported in the fore period, a few 

 in the first part and a very few in the latter part of the preservative 

 period, and a very few in the latter part of the after period. 



No. 1 1 shows a very few crystals in the fore period and at the second 

 and third tests in the preservative period and none in the after period. 



For No. 12 a very few crystals are reported in the last part of the 

 preservative period. There is a slight indication of an increase in the 

 oxalate of lime crystals during the preservative and after periods, 

 which is about in proportion as expressed by the figures representing 

 the aggregate relative occurrence, namely, 27.3 for fore period, 45.7 

 for the preservative period, and 54.5 for the after period. 



CRYSTALLINE PHOSPHATES. 



No crystalline phosphates are observed in the urine of Nos. 2, 3, 4, 

 5, 6, 7, 8, 9, and 12. 



A very few crystals are found in the case of No. 1 in the first part 

 of the preservative period. 



A few are found in the case of No. 10, and a very few in the case of 

 No. 11, in the fore period. 



AMORPHOUS PHOSPHATES. 



No amorphous phosphates are found in any case with the exception 

 of No. 5 in the after period, and No. 10 in the fore period,' a few being 

 observed in both cases. Both forms of phosphates are seen to occur 

 infrequently in the urine ; a slight tendency is indicated, however, to 

 suppress these forms during the preservative period, as shown by the 

 figures for their relative occurrence.
