On the 2nd day of this month Roelof Siegers, a sailor born in Norway, came to me with complaints. I learned that he had been ill for about four weeks in the fatherland. He had debris quotidiana, a regular fever; he was vomiting and he could not eat. I gave him a laxative and a powder against fever (prescription 1).
