204 INFLUENCE OF FOOD PRESERVATIVES ON HEALTH. 



Other fonns of casts. No other forms of casts are found in any 

 instance. 



Mucous cylindroids. These are found in every instance, and they 

 are fairly abundant in the first examination of No. 8, in the fourth 

 examination of No. 9, in the first, second, and third examinations of 

 No. 10, in the fourth examination of No. 11, and in the third examina- 

 tion of No. 12. They are abundant in the second examination of No. 

 7, in the second and fourth examinations of No. 8, in the first and 

 second examinations of No. 9, and in the fifth examination of No. 12. 



Mucous strands. These are found also in every instance. They are 

 fairly abundant in the second and third examinations of No. 10, in the 

 fourth examination of No. 11, and in the second and fourth examinations 

 of No. 12. They are abundant in the first and second examinations 

 of No. 7, in the first, second, and fourth examinations of No. 8, in the 

 first and fourth examinations of No. 9, and in the first and third exam- 

 inations of No. 12. They are extremely abundant in the second 

 examination of No. 9 and in the fifth examination of No. 12. 



A general summary of the above data, while giving interesting infor- 

 mation in regard to the occurrence of these microscopical bodies in the 

 urine, fails to reveal any definite connection between the abundance of 

 the occurrence and the influence of the preservative administered. 



SERIES V. 



Ten examinations were made for the bodies under discussion during 

 the fifth series one during the fore period, eight during the preserv- 

 ative period, and one for the after period. (See Table XL1V, p. 210.) 



Uric-acid crystals. No crystals of uric acid are found in the cases of 

 Nos. 4 and 6. No. 4, however, left the city before the end of the period. 

 The crystals are found only once in the cases of No. 3 and No. 5, and 

 then only a very few are present. They occur quite frequently in the 

 case of No. 1 and at the last examination are abundant. The}'' also 

 appear quite frequently in the case of No. 2 during the preservative 

 period, but at no other time. These data show a slight tendency on 

 the part of the preservative to increase the number of uric-acid crys- 

 tals, although the greatest number was found in the case of No. 1 in 

 the after period. 



Urates. U rates are found only in the case of No. 2, and that about 

 the middle of the preservative period. They are fairly abundant at that 

 time, but rapidly disappear. There may possibly be some connection 

 between their appearance and the administration of the preservative, 

 but it is not very strongly brought out. 



Oxalate of lime. Oxalate of lime crystals are found in every sam- 

 ple except one in the cases of Nos. 1 and 3. They become abundant 

 in the case of No. 3 toward the end of the preservative period and 

 during the after period. They occur irregularly in the case of No. 1. 

 The crystals are found at first in the case of No. 2, but disappear after
