SALICYLIC ACID AND SALIC YLATES. 577 



Finely granular casts. The finely granular casts were present to a 

 much less extent than the hyaline casts, and the figures for relative 

 occurrence, namely, 83.3, 56.3, and 39.1, indicate a continued decrease 

 throughout the experiment. In the case of No. 3 they were not found 

 at all, and in the case of No. 11 only once, when a very few are reported; 

 for Nos. 7 and 10 verj- few were reported twice, and for Nos. 4, 8, 

 and 12 three times. In only one instance, during the fore period of 

 No. 1, were more than a few casts reported. 



Coarsely granular casts. These casts occur to a still less extent than 

 the finely granular, as indicated by the figures for relative occurrence: 

 Fore period, 41.7; preservative period, 35.4, and after period, 39.1. 

 These figures show a slight tendency for the casts to decrease during 

 the preservative period and increase in the after period. The individ- 

 ual figures show that these bodies did not occur at all in the case of 

 Nos. 5, 10, 11, and 12, and were present to the greatest extent in the 

 cases of Nos. 1. 2, and 9. 



Epithelial casts. Epithelial casts were reported in only one instance, 

 very few being observed in the case of No. 8 in the preservative period. 

 Other forms of casts were reported also in one instance, namety, a 

 report of very few in the case of No. 8 during the preservative period. 



Mucous cylindroids. These bodies were found for all individuals 

 and at every observation taken. They were present to the greatest 

 extent in the case of No. 6, being numerous throughout the preserva- 

 tive period and extremely numerous in the after period; only a few 

 are reported in the fore period. Only in the cases of Nos. 5 and 7 are 

 they reported as numerous, a few or a very few being reported in the 

 other cases. The average figures given indicate a decided increase of 

 these bodies in the preservative period and a slight decrease in the 

 after period. 



Mucous strands. The presence of mucous strands was marked in 

 all cases and in the cases of Nos. 6 and 7 they are recorded as being 

 numerous or extremely numerous at every examination. The aver- 

 ages show the prevalence of this condition, being 183.3 for the fore 

 period, 220.8 for the preservative period, and 243.5 for the after period, 

 the increase in the after period being greater than in the preservative 

 period. 



GENERAL CONCLUSION. 



A general view of the microscopical examination of the urine shows 

 many instances in which thfc specific effects observed can be attributed 

 to the exhibition of the preservative. 



The fact that the data as expressed by the figures represent onty 

 approximations must be remembered HI reading the text on the tables, 

 and also that the variations are evidently great from day to day and 

 only a comparatively small number of observations were made. It is
