We worked together till midday.

We then took half-an-hour's walk in the park, as we were accustomed to do, before breakfasting at the chateau.

After breakfast, we took another walk for half an hour, and then returned to the laboratory.

There we found my chambermaid, who had come to set my room in order.

I went into The Yellow Room to give her some slight orders and she directly afterwards left the pavilion, and I resumed my work with my father.
