    3. NOVOCAIN SUPRARENIN COMBINED At a congress of German dentists held in Mnenster, Ger- many, at whicli tlie German authorities on local anaesthesia met, Seidel proposed sixteen theses formulating use and dosage of the Novocain-Suprarcnin solutions. The problem was thor- oughly discussed by Fischer, Apffelstaedt, Moral, Steinkamm, Hauptnieyer, Buente, Friedmann, Heinenianii, Endres, Rilke and Heinze during the two days' meeting and finally accepted by unanimous vote as follows: SEIDEL'S 16 THESES I. The fresher a Novocain-Suprarenin solution is, the less is its toxity, and the greater is its anaes- thesia producing power. Therefore when exam- ining preparations scientitically, one should only use freshly self-prepared solutions. One can only get a clear picture of the power of the Novocain- Suprarenin solutions, if one is sure that the solu- tion used contains Novocain and Suprarenin pure, and not products of deterioration. II. Fresh Novocain and Suprarenin either sep- arate or mixed (solutions) should be clear as water. III. For the practice a Novocain solution should only be considered fresh and fully active, if clear and colorless. IV. The same is true for solutions of supra- renin. Solutions of suprarenin are less stal)le the more diluted they are. V. Mixed Novocain-Suprarenin solution is only to be considered fresh directly after the mixing of tlie dissolved ])arts.
