Ye ourselves, will be able to get rid of the matrix 1 think ao that ve can determine the particle elze of the quartz. Z would extlmate that the coet of making the pre liminary tests and partlole size determination and so on would not xoeed 9300. With this information in hand, you can then decide whether you care to go into an experiment of a larger soale for vhioh our charge la $5,000 for the first year and leas in the succeeding ones as the number of animals to be kept under observa tion decreesee. approval.
