This centrifuge is so constructed that a speed of from i,ooo to 3,000 revolu- 
tions per minute can be easily maintained with the urine or milk sedimentation 
apparatus and by simply removing the crank from the low-speed axis and trans- 
ferring it to the high-speed axis, a speed of 10,000 revolutions and upwards can 
be attained without undue exertion with the Daland's Hematokrit attachment 
(or sputum precipitating tubes) in position. 
The gearing is excellently made and runs very smoothly and evenly with com- 
paratively little noise and vibration.
