"I long ago suggested the hypothesis, that in the basin of the Thames there are indications of a meeting in the Pleistocene period of a northern and southern fauna"
About this Quote
The phrase “in the basin of the Thames” is shrewdly local. Rather than pointing to some exotic frontier, Lyell anchors deep time in Britain’s most symbolically loaded landscape. The subtext: the ground beneath the empire’s capital contains a prehistory that dwarfs contemporary politics. Geological time becomes a quiet rebuke to national self-importance, and also an invitation to readers: you don’t have to travel to encounter the planet’s vastness; you’re already standing on it.
The real rhetorical engine is “meeting in the Pleistocene period of a northern and southern fauna.” “Meeting” humanizes climate history without sentimentalizing it. It implies migration, collision, overlap - a dynamic border zone rather than a static museum display. In Lyell’s era, this kind of language helped geology argue against tidy, one-time catastrophes and for slow, legible processes: species ranges shifting with ice, rivers, and temperature.
Context matters: mid-19th century Britain is obsessed with classification, with drawing lines. Lyell’s sentence is about blurred lines - northern and southern, then and now - and it uses the calm tone of legal reasoning to smuggle in a radically destabilizing scale of time.
