What does the Latin abbreviation "celⁱˢ" mean?

What does this Latin abbreviation mean?:

celⁱˢ

Context: I’m trying to translate:

@original Latin

…ex qua absque ulla ulteriore suppositione leges illæ notissimæ a celⁱˢ Ampère, Neumann, Weber, conditæ sua sponte emanabunt.

Is this a correct translation?:

@translation

…from which (without any further supposition) those well-founded laws of Ampère, Neumann, Weber, on their own foundations, spontaneously emanate.

Thank you

My guess is celebrandis. But it’s but a guess.

Nice guess, thank you
That seems to fit the context very well.
