![Certificate from Dii. Segnitz of Gelnhausen, Duchy of Hessen. [Translated from the German original.] For upwards of two years I have prescribed Dr. de Jongh’s cod liver oil instead of that which is generally used in Germany. With the desire of making known the truth, I am bound to state that this oil is greatly superior to all other kinds previously used by me, and that therefore the objoct aimed at by the use of this remedy is more surely attained by this oil than by any other kind. It is true that, in some cases of scrofula and tubercular diseases, the simultaneous use of this oil with the ioduret of potassium becomes necessary, but this in no way affects the opinion which I have ex- pressed. _ (Signed) Du. Segnitz. Gelnhausen, July 1, 1851. Certificate from Dr. Van den Eynden, Emmerich. [Translated from the German original.] 1 have prescribed Dr. de Jongh’s cod liver oil for a considerable time with the most satisfactory results ; and I can conscientiously recommend it to my colleagues as being superior to all other kinds. (Signed) Dr. Van den Eynden. Emmerich, Jan. 22, 1852. Certificate from the Royal Police op Prussia. [Translated from the German original.] In answer to your letter of the 2nd ult., requesting permission to sell Dr. de Jongh’s cod liver oil in bottles, accompanied wi i id, sLp and signature, the .Royal Police of Prussia (Komghch^- polizei-Praesidium) has the honour of informing you that it I ■ caused the sample which you have forwarded to be submitted to an official investigation, and that the result of such myesfagatmu has proved it to be not only the genuine cod liver oil, but still further that it is of a kind which distinguishes itself from the cod liver oil in ordinary use, alike by its taste and cl^jnical con - position. Considering moreover that it has come to their_know led-e that physicians generally recommend the use of Vi. e Jongh’s oil in preference te the cod liver oil in ordinary use, the Royal Police accedes to your request.
