There will be no diffi culty at all in making up some more of this material and sending it to you, and I am writing to East St, Louis to have this done, I presume it may take a week or two to get it prepared, but I would hope that you would have it by the first of the year. In this connection, I wonder if you still would be interested in having us prepare the precipitated hydrate of the type that you made (containing some chloride) and which you found was active? When I was in St Louis I talked with our people about it and found they could quite easily prepare several pounds of this material for you in the laboratory, Of course you would have to do the final grinding operation in order to get the fineness you desire. If you would like to have ns do that, please let me know, and also give me the- detail directions as to the method which you employed, so that we may be sure to -get the same kind of material. ECE:ICL - Tery truly yours
