 the members of the series, due to grippe and other diseases, render any 

 discussion of this relative abundance in connection with the administra- 

 tion of the preservative impracticable. 



SERIES III. 



Four examinations were made for these bodies in the urine during 

 the third series. The first examination was made on February 19 and 

 20, at the "beginning of the fore period; the second examination was 

 made on March 1-2, at the end of the preservative period; the third 

 examination was made on March 17, during the after period, and the 

 final examination was made on March 20, at the end of the after 

 period. (See Table XLI1, p. 208.) 



Uric-acid crystals. During the fore period no uric-acid crystals are 

 found in any instance. The same is true of the preservative period. 

 In the after period uric-acid crystals occur in the cases of Nos. 1 and 2, 

 and in the case of No. 2 these crystals are fairly abundant at the close of 

 the after period. 



Urates. No urates are found in any of the samples during any of 

 the periods. 



Oxalate of lime. Crystals of oxalate of lime are fairly abundant in 

 the case of No. 3 in the fore period, diminishing slightly in the preserva- 

 tive period. They are again fairly abundant in the first examination of 

 the after period and extremely abundant in the final examination of the 

 after period. In the case of No. 6 no crystals of oxalate of lime are 

 found in the fore period. The} 7 appear in the preservative period, 

 there are a few in the first examination of the after period, and an abun- 

 dance in the second examination of the after period. In the case of 

 No. 4 oxalate of lime crystals are found only during the first exami : 

 nation of the after period. In the case of No. 5 these bodies are found 

 only in the second examination of the after period. In the cases of 

 Nos. 1 and 2 oxalate of lime crystals are not found at any period. 



Crystalline phosphates. No crystalline phosphates are found in any 

 instance except in the case of No. 5, where a very few occur during the 

 last examination of the after period. 



Epithelium cells. These are found throughout the examinations 

 in all cases. In the fore period they are fairly abundant in the case of 

 No. 6. In the preservative period they become abundant in the case of 

 No. 2 and fairly abundant in the case of No. 6. In the first examination 

 of the after period they are abundant in the cases of Nos. 2 and 6. 

 In the second examination of the after period they are fairly abundant 

 in the cases of Nos. 2 and 6. No examination was made in the case of 

 No. 4 during the preservative period. 



Leucocytes. These bodies appear in all instances at every examina-
