His collection was a large one, consisting of forty boxes and barrels of fossils. The result of this study was the determination of a section beginning early in Ordovicic time, having a thickness of 540 feet, followed by 19 miles of sea, when the section again begins high in the Ordovicic and continues well up into the Siluric through 2,300 feet of limestones and shales.2

Richardson’s sections are in all essentials still correct and the stratigraphic foundation upon which all subsequent work for this region must be based.

The fossils of Anticosti were studied by Billings, and he states that during his preliminary work “an opportunity was afforded me of . . .
