To test the ether solution it is only necessary to pour some of it in a test tube containing a little very dilute ferric chlorid solution and shake. The aqueous solution assumes a color proportionate to the amount of methylene-di-salicylic acid in the ether.

Having myself taken this quantity of ur-a-sol I feel justified in saying something concerning the taste of the stuff, although this is a point that hardly deserves the discussion it has received in the appended communications. The taste of a drug to a healthy person who takes it as an experiment is apt to be very different from the taste to a person who is sick and who believes or hopes that the drug will cure him. To me the stuff called ur-a-sol was very disagreeable, and I had the taste of it in my mouth the entire day. Only once did it have any nauseating effect. That again is, however, largely a matter of personal idiosyncrasy. It will be noted that Prof. Sadtler now admits a more pronounced salicylic taste (p. 12). It is rather curious that he should have obtained this impression from less than a gram, but not from a "pinch" of the product which has such a slight solubility as ur-a-sol.
