I looked it up.
In his first edition of Origin of Species, Darwin put the end of the Cretaceous Period at 300 million years. That estimate came in for criticism from geologists, who persuaded him that it was too long a time span given what they (thought they) knew about the subject. So in the second edition, he lowered is estimate to 150 million years. After still more criticism, he further attenuated his views in order to get closer to the 100 million years that scientist whom he respected thought likely.
The truth is that the Cretaceous Period ended around 66 million years ago, when the last mass extinction occurred. So Darwin was indeed incorrect in his surmises.
But there was never any question of a thousands-of-years age of the earth. If Darwin thought the last period before now was measured in hundreds of millions of years, he almost certainly thought the world's existence was measured in billions of years.
