That's interesting to know, thanks. Of course all of the four minute records
were recorded at 200 tpi. Still an achievement that early in the game. The
1899 cylinder I speak of was 450 tpi. (I am going to check this out for
certainty as that number is from memory) If I'm wrong on that number I will
repost the correct tpi.

Looking at our re-issued Program to the Electric Club (delivered by Ezra
Gilliland on May 19, 1888), I see, on p. 9, a reference to 'brown wax'
cylinders recorded at 200 tpi.
