206 INFLUENCE OF FOOD PRESERVATIVES ON HEALTH. 



Hyaline casts. These bodies are found in nearly everj^ instance. In 

 the cases of Nos. 1 and 2 they appear to be more frequent during the 

 preservative period. In the case of No. 3 there is no definite relation 

 evident, and the same is true of No. 5. In the case of No. 6 there 

 seems to be a diminution in the number of hyaline casts during the 

 latter part of the preservative period and a considerable increase dur- 

 ing the after period. In this case also the data are not conclusive. 

 The preservative appears to increase the number of casts in some 

 instances and diminish them in others. 



Finely granular casts. These bodies are also found in most cases. 

 In the case of No. 1 there is an apparent increase in the number dur- 

 ing the preservative period. This is also true of No. 2, although in 

 the latter part of the preservative period these casts disappear alto- 

 gether. In the case of No. 3 the casts do not appear to be influenced 

 by the administration of the preservative, and the same is true of No. 

 5, while in the case of No. 6 there is apparently a larger number dur- 

 ing the fore and after periods than during the preservative period. 

 Here again the data are not conclusive. Apparently the preservative 

 tends to increase the number of casts in some instances and diminish 

 them in others or to have no influence at all. 



Coarsely granular casts. These are found in the majority of samples 

 under examination. In the case of No. 1 the larger number was 

 found during the administration of the preservative. This is true 

 also in a marked degree in the case of No. 2. In the case of No. 3 

 there seems to be no effect produced by the preservative on the num- 

 ber of casts. In the case of No. 5 none is found during the fore and 

 after periods, and in three instances during the preservative period 

 none is found. In the case of No. 6 none is found during the fore 

 period; casts are found five times out of eight during the preservative 

 period, and they are also found in the after period. Here again the 

 data are not conclusive, the preservative appearing to increase the 

 number of casts in some cases and to have no effect whatever or a 

 tendency to diminish the number in other cases. 



Epithelial casts. These are not found in any case except that of 

 No. 6, where they are found once at the beginning of the preservative 

 period and once in the after period. 



Other forms of casts. No other forms of casts than those above 

 mentioned are found, except in one instance in the after period in the 

 case of No. 6. 



Mucous cylindroids. These are found in all cases, but the inspec- 

 tion of the data does not reveal any apparent effect of the preservative 

 in either increasing or decreasing the number present. They are 

 abundant in four examinations of No. 1, one of No. 4, five of No. 5, 

 and two of No. 6. They are extremely abundant in three of the 

 examinations of No. 6 and one of No. 5. These variations in numbers 

 in the case of No. 6 may seem to be connected with the use of the 

 preservative, but the relation is not distinctly marked.
