To the Editor:  —Considerable interest has been aroused in Congress concerning the abrogation of the patent rights on salvarsan. This drug was patented by Ehrlich and Bertheim, citizens of the German empire. These patents were assigned to Farbwerke vorm. Meister, Lucius and Bruening of Hoechst a. M., Germany, a corporation. No American name so far as we could learn was mentioned.There is a branch of this firm, or an agent, in New York who has entire charge of the sales in the United States. The patents are very comprehensive and cover the process of manufacture, the chemical substance, the method of puting it into ampules, the process of preparation just prior to its being used and, finally, the name is trade-marked. Under the patent on the process of manufacture No. 986144, there are five separate claims. In order to show the breadth of these rights we cite claim No.
