The 18th of this month Jacobus Rankin, a sailor born in The NetherlandsVeere, came to me with complaints. He had a headache and was vomiting. He had also been on the boat to GhanaElmina Castle and there he had drank much palm wine and he had eaten many inland fruits. This made his stomach completely rotten. I also found out that he had an infectious disease. I gave him one scruple of a emetic, which made him puke out two large worms. I also give him one scruple of pulverized mirabilis jalapa as a purgative. Furthermore, because he also had a fever, I gave him pulverized anti-fever (prescription 1) and a barley drink (prescription 14). This made him recover and he took his shift again on the 31st of this month.
