The Centrifugal Method of Preparing Urine for Micro- 

 scopical Examination. — A specimen of urine was di\ idcd be- 

 tween two examiners. One employed the centrifugal method, 

 found no casts, and insured the man who was being examined for

 hours in a conical glass, found hyaline casts, and declined the risk. 

 This woidd seem to con«lemn the centrifugal method.
