We have, at least, been able to interview Daddy Jacques--as he is called in the country--a old servant in the Stangerson family.

Daddy Jacques entered The Room at the same time as the Professor.

This chamber adjoins the laboratory.

Laboratory and Yellow Room are in a pavilion at the end of the park, about three hundred metres (a thousand feet) from the chateau.
"'It was half-past twelve at night,' this honest old man told us, 'and I was in the laboratory, where Monsieur Stangerson was still working, when the thing happened.

I had been cleaning and putting instruments in order all the evening and was waiting for Monsieur Stangerson to go to bed.
Mademoiselle Stangerson had worked with her father up to midnight; when the twelve strokes of midnight had sounded by the cuckoo-clock in the laboratory, she rose, kissed Monsieur Stangerson and bade him good-night.
