 Kellicott, D. S. — An efficient Pipette. [Ante, p. 180.] 



["An equally good, perhaps better, way to secure a pipette with all required 

 advantages is as follows: — Take a proper piece of large rubber tubing, 

 e.g. 3 in. long, with half or three-fourths inch bore, and two short rubber 

 corks to fit, pass the tube through one stopper and into the other ; drill a 

 hole in the glass tube near the upper one, and bring all to place. This 

 form works promptly, is durable, and has one advantage, when laid on the 

 work-table the point is free from the same, so it does not gather dust.]
