It is very possible that for the pressures that we had in these tests, 
the bubbles that were off the surface never really reached, or very 
few of them reached, the region at the vapour pressure of the water. 
Iam not sure of the extent of the work that will be carried 
out, Professor Mazarredo, as far as the influence of speed is con- 
cerned. The work requires a lot of effort and making detailed mea- 
surements at various speeds in water tunnels could be significant, 
but it is possible that the towing basin work which was done ata 
speed twice as high may, at least for the time being, serve our pur- 
poses of analysis. 
I appreciate all of discussion and I'd like to thank all of you 
for giving the pertinent and valuable comments.
