I rang for the tea, and the waiter, reappearing with his magic clew, brought in by degrees some fifty adjuncts to that refreshment, but of tea not a glimpse.

adjuncts = accompanying items

Definitions:

(1) (adjunct)
someone or something added to support, assist, or supplement another -- often in a secondary, temporary, or non-central role
(2) (meaning too rare to warrant focus)
More specifically, in grammar or linguistics, an adjunct can refer to a part of a sentence that, when removed, will not affect the remainder of the sentence. For example, the sentence "Joan jogged in Central Park on Sunday," has two adjuncts: "in Central Park" and "on Sunday".

The phrases adjunct faculty or adjunct staff can mean both that the employees are in a support role and that they are on temporary assignment.
