URINALYSIS. 1 39 



How is uric acid formed for experimental purposes? 



Take 10 c.c. of urine and 2 c.c. of hydrochloric acid ; 

 put the acid in the urine and set aside for two hours. 

 Examine under the microscope. 



Note the shape of the crystals. 



What is meant by the acid tide and the alkaline tide? 



MICROCHEMIC ANALYSIS. 



Take a drop of urine to be examined and put it on 

 the slide ; also a drop of the reagent to be used. Place 

 it on the slide near the urine, put a cover-glass on the 

 drops, and watch the reaction. 



Set a method by which you will always work in your 

 own office or laboratory. 



ABNORMAL, CONSTITUENTS IN THE URINE. 



Albumin in the urine is the first to consider. Albu- 

 min is coagulated by heat and certain chemicals, so we 

 make use of these principles in our analysis. 



Exercise No. i. Secure your key and clean out your 

 locker. Keep your locker locked. Note the quan- 

 tity of a liter as the demonstrator measures it out. 



Each student should collect the urine for 24 hours 

 from a patient and bring it to the laboratory to analyze.
