BOKIC ACID AND BOBAX. 199 



MICROSCOPICAL EXAMINATIONS. 



Microscopical examinations of the urine were made for the follow- 

 ing substances: 



(1) Uric acid crystals. 



(2) Urates. 



(3) Oxalate of lime. 



(4) Phosphates: 



(a) Crystalline phosphates. 

 (6) Amorphous phosphates. 



(5) Epithelium cells of all kinds. 



(6) Leucocytes. 



(7) Red blood cells. 



(8) Casts: 



(a) Hyaline. 



(6) Finely granular. 



(c) Coarsely granular. 



(d) Epithelial. 



(e) Other forms. 



(9) Mucous cylindroids. 

 (10) Mucous strands. 



The data relative to these examinations are contained in the tabular 

 statement given herewith. (Tables XLI-XL1V, pp. 207-211). The 

 relative abundance of the various bodies is represented as follows: 

 None,0; very few, 1; few, 2; fairly abundant, 3; abundant, 4; extremely 

 abundant, 5. 



SERIES II. 



Uric acid crystals. This examination was not instituted until after 

 the close of the first series, and the first test was made during the 

 second series, three days after the close of the fore period. The second 

 examination was made on February 20, near the close of the supple- 

 mental preservative period. In no instance were uric acid crystals 

 found. 



Urates. A similar examination was made for urates, with the same 

 result. 



Oxalate of lime. The urine was also examined at the same time for 

 crystals of oxalate of lime. In the urine of No. 8 a considerable num- 

 ber of crystals was found during both periods. In the case of No. 9 

 a very few crystals were found during the second period. In the case of 

 No. 11 crystals of oxalate of lime occurred during the first period, but 

 none during the second, an^d the same is true in the case of No. 12, 

 only the crystals were less abundant. 



Crystalline phosphates. No crystalline phosphates were found in 

 any of the samples at either period of examination. 



Amorphous phosphates. Amorphous phosphates were found to be 

 abundant in the urine of No. 8 during the second period of observa- 

 tion, but in no other case did they occur.
