Ordinary Meeting, March 22nd, 1870. 
E. W. Binney, F.R.S., F.G.S., Vice-President, in the Chair. 
Mr. James Teale, of Springfield, Sale, was elected an 
Ordinary Member of the Society. 
A letter from Mr. H. Wilde was read, stating that since 
the last meeting he had made a few experiments “ On the 
Suspension of a Ball by means of a Jet of Water,” and had 
found that the behaviour of the ball was the same in vacuo 
as it is in air. 
Mr. R Routledge stated that he had also made a few 
simple experiments, and had found that when a string was 
attached to the ball in such a manner as to prevent or 
impede its rotation about a horizontal axis, it was no longer 
continuously sustained by the jet. Also when the jet 
(directed horizontally to avoid the interference of the falling 
drops) was brought very near to the light ball suspended by 
a thread, the ball showed no tendency to move towards the 
jet. This invalidates the surmise that the jet is accom- 
panied by a current of air which tends to carry the ball into 
the jet. 
Professor Osborne Reynolds, B.A., said : After the 
discussion which followed my paper on this subject at the 
last meeting of this Society, I thought it would be well to 
substantiate as far as I could the truth of my hypothesis by 
experiments ; and the following is a description of what I 
have done in this way. Before describing the experiments, 
I will mention the immediate objects for which they were 
severally undertaken. First, I wished to show that the air 
was not the medium by which the water acted on the ball,
