[" The glass tube passes completely through the ball, the end of the tube. 

 being closed with a cork or hermetically sealed; holes for suction being 

 drilled through that portion of the tube enclosed within the ball. The 

 advantages of this contrivance lie in the increased firmness in handling 

 the pipette, and consequently greater suction-power."]
