I. Some Novel Phenomena of Chemical Action attending 

 the Efflux from a Capillary Tube. By R. S. Dale, 

 B.A. 



Read December i6th, 1884. 



The results obtained in the experiments I propose to 

 describe were the outcome of a desire to know what, if 

 any, mechanical action took place when two solutions 

 capable of forming a precipitate were slowly mixed; 

 next to find the nature of such mechanical action, and 

 latterly, if possible, to measure it. I have made no 

 attempt in the latter direction, but propose describing a 

 series of experiments which have yielded some very novel 

 effects.
