Merck almost thirty years ago at the request of university professors. It is mentioned in the Ergänzungsbuch zum Arzneibuch des deutschen Reichs (1906) and the British Pharmaceutical Codex (1907). There is, therefore, a demand for it, which it is our business to satisfy. Whence such demand emanates, whether from scientific investigators or from practicing physicians, we have no means of ascertaining. Both classes look to us to supply their needs through regular trade channels.
