Ralph,
I don't know what possessed me to write balata, as you said, it was gutta.
Hutchinson, as you know, was an expert witness at the trial and he wrote:
"it does seem to my uninstructed wisdom that if ever there were a substantially new invention, making a new departure, it was this of these that we then called Haskells and now call India-rubber-cored balls. Nobody, before Haskell, had ever given them to us as reasonable things with which to play the game of golf"
His full account left me with the impression that the proceedings were a combination of circus and courtroom, and that the vast amount of money to be made from the ball was behind the denial of Haskell's patent, i.e. he would have had a monoply.
