Why couldn't the Royal Society publish Newton's Principia?

The Principia was eventually published in 1687. After publishing the work, the Royal Society told Halley it could no longer afford his salary and offered to pay him in unsold copies of the Historia Piscium instead.

Explanation:

But the Royal Society refused to fund the book because it had suffered huge financial losses publishing 'The History of Fish', an indigestible tome of piscine anatomy which barely sold and nearly bankrupted the institution.
