THE MICROSCOPE. 175 



large enough, in one part, to show that it was probably made of the 

 disorganized cellular lining. It diminishes in size to the calibre of 

 the tube when intact. The clear portion is probably the mucoid 

 matter of Beale. In the middle of the field is a patch of tessellated 

 epithelium from the bladder, some scattered cells with strongly- 

 marked nuclei and spindle-shaped cells, probably from the blad- 

 der. At the right are "compound granule corpuscles." 



This appearance of the deposits is quite usual on and after 

 the fourth day. 



Fig. 3 represents the deposits found in the urine of a robust- 

 framed white male, aged forty-five, who slowly regained his usual 

 health. This urine was voided without difficulty on the eleventh 

 day after the primary chill. It was acid, deep-red yellow, 1.024 

 specific gravity, normal in quantity, and about one-fourth albumin- 

 ous. It contained bile pigment and a heavy lateritious deposit. 

 The amorphous urates, being so abundant, obscured other objects. 

 Gentle heat was applied, and the microscope presented a field as 

 seen in this figure, viz.: tube-casts, granular, epithelial and hyaline, 

 renal and vesical epithelium, stained yellow. The worm-like mucoid 

 casts were of a yellow tinge. 



Fig. 4 represents the objects seen in the deposit from the 

 urine of a woman aged thirty, and at the fifth month of gesta- 

 tion. It was voided on the fourth day, and the woman died on the 

 seventh day of the fever. The urine was acid, scanty, bright yellow 

 and one-third albuminous. It contained epithelium from the 

 vagina, urinary passages, and kidneys, small waxy casts, with a 

 sharp fracture, some imbedded in granular matter, and one contain- 

 ing granular matter in its axis. All the objects were stained yellow. 



Fig. 5 represents the microscopical appearance «in several cases 

 examined on the third day before the occurrence of albuminuria. 

 The objects are, squamous, round, and transitional epithelium from 

 the bladder, and spindle-shaped cells probably from the pelvis of the 

 kidney. Sometimes they were in patches which covered half the 

 field. They were found sparingly in some mild cases . in which 

 albuminuria did not occur. 



Fig. 6 shows the deposit from the urine of a man, aet. 45, who 

 was convalescent on the twelfth day of the fever. This urine, 

 which was passed on the fourth day, was alkaline, yellow from bile 

 pigment, not albuminous, and gave a light deposit. In this figure
