Could you please help me understand what is written here?

Hello

Could you please help me transliterate the following quote? I can't understand some symbols and words.

"Ego eluris, [???] simus ascriberem, paruas enim, [???] exiles genas habent, [???] sunt furaces, va fre, [???] insidiose, [???] per hec animalia etusdem ingenu homines deprehenduntur, qui scilicet clam insidiosi, vafri, [???] maligni sunt."

Also, why do some letters have an "umlaut" and an acute or grave accent? It doesn't make sense to me.

Thank you in advance!
