I don't know what is supposed to be
St. James's
here.
================================
from: Pride and Prejudice
For, though elated by his rank, it did not render him supercilious; on the contrary, he was all attention to everybody. By nature inoffensive, friendly, and obliging, his presentation at St. James's had made him courteous.

Thanks for help,

St. James's Palace is the senior Palace of the Sovereign, with a long history as a Royal residence. In Jane Austen's time, it was where the King lived in London and it is where someone would be introduced into top Society. In this passage, is is made clear that although "he" moves in the "best" circles, he is still considerate and polite to everyone.
Thanks,
