We also succeeded in the same way in blowing a very homogeneous and regular sheet of asbestos felt on a frame on which was stretched a mosquito screen on top of which was stretched cheesecloth. In fact the latter method seems to be very practicable and will allow us to make asbestos felt or ready made diaphragm which can afterwards be applied on the perforated cathode sheets. The whole thing seems to be an assured success and confirms the excellent results I obtained some two months ago when I first attempted to produce asbestos felt for diaphragms in this

way. The felt impregnated with silicate dries very hard. I ought to have used less silicate. This ought to be tried again in with more diluted solutions of silicate
My attempt to improve the iron oxid paint of the old style diaphragms and make the latter less porous thus reducing initial percolation has been very successful too.  I tried the addition of soap. Soap and pulverized resin and starch. The latter had to be abandoned unless the starch be boiled because the paint dries brittle although it applies well.
