On the 28th of this month, as we were lying before the fortress of Chama, our captain Jan Minkenveld came to me. He complained bout pain in all of his limbs and about vomiting. I found that he had a fever intermittens, sporadic fever. He asked for a doses of laxative pills as he had an aversion to taking powders.

I gave him five pills (prescription 12) of the kind that I had given him often before, and he said that they were easy on him. Afterwards, as the vomiting and fever got worse, I prescribed another mixture (prescription 13). I could not get him to take an emetic on my request.

Since he strongly complained about pain in his head, which in my view was caused by the fever, I also laid two bandages on his head. During the fever attacks he was delirious. I boiled a barley drink (prescription 14) for him, of which I let him drink to his satisfaction.
