200 INFLUENCE OF FOOD PRESERVATIVES ON HEALTH. 



Epithelium cells. These bodies were found in all samples during 

 both pei'iods of examination. They were more abundant during the 

 second period than the first. 



Leucocytes. Leucocytes were found in all samples during both 

 periods. There is scarcely any difference in the relative abundance of 

 these bodies during the two periods of observation except in the case 

 of No. 8, where there was an increase in the number during the sec- 

 ond period. 



Red blood cells. Red blood cells were absent in all cases, except in 

 the case of No. 8 during the second period, when some of these bodies 

 were found. 



Hyaline casts. Hyaline casts were found in two instances during 

 the first examination, namely, in the cases of Nos. 10 and 12, and in 

 all of the samples during the second period of observation, being 

 fairly abundant in the case of No. 7. In the case of No. 10 there was 

 a diminution in the number found as compared with the first period. 



Finely granular casts. These were present in two instances in the 

 first examination, namely, Nos. 10 and 12, and also in two instances dur- 

 ing the second period, namely, Nos. 9 and 12, the number increasing 

 in the case of No. 12. 



Coarsely granular casts. These were found in only one instance in 

 the first period, namely, that of No. 12, and during the second period 

 of examination once in the case of No. 9. 



Epithelial casts. Epithelial casts were entirely absent in all cases 

 during the first examination and occurred only in the case of No. 12 

 during the second. 



Other forms of casts. Forms of casts which appeared to be hyaline 

 pus casts were found in the case of No. 12 during the first examina- 

 tion, but had disappeared at the time of the second examination. 



Mucous cylindroids. Mucous cylindroids were present in all 

 instances during both the first and second examinations. They were 

 somewhat more abundant during the second examination in the case of 

 No. 8 and less abundant in the case of No. 10. In the other cases the 

 relative abundance during the two periods was unchanged. 



Mucous strands. These bodies were present in all cases during both 

 examinations. During the first examination they were abundant in 

 the case of No. 7 and extremely abundant in the case of No. 9. Dur- 

 ing the second examination they were extremely abundant in the cases 

 of Nos. 7 and 8. The strands increased in abundance at the period of 

 the second examination in the cases of Nos. 7, 8, 10, and 12. They 

 diminished in abundance in the second examination in the case of No. 

 9 and remained unchanged in the case of No. 11. 



The above data show that very little change in the relative abun- 

 dance of the various bodies mentioned occurred between the time of the 

 first and second examinations. There is shown, however, a slight tend-
