Having learnt that the President de Meme wanted to reside himself at Balagni, he quitted it, and retired to Senlis in the beginning of August: in October he came back to Paris.
His wife's affairs obliging her to make a journey to Zealand, she set out for that province in the summer 1624.

In her absence Grotius was seized with a violent dysentery.

October 18th, 1624, he writes to his brother that he had been three weeks confined to his bed, and four times blooded.

The news of his illness threw his wife into a fever.

As soon as it was abated she set out for Paris without waiting the return of her strength.
