A mineralogist at Besançon had just sent us a collection of siliceous nodules, which I had to classify: so I set to work; I sorted, labelled, and arranged in their own glass case all these hollow specimens, in the cavity of each of which was a nest of little crystals.
Ik ging aan het werk. Ik schiftte en schikte in hunne hokjes al die holle steenen, waarin kleine kristallen zweefden.
