Lockerby has translated the first word as "peraetumes" and then says it is to be understood as "'peractum', a book for teachers and students".
Peraetumes or even Peractumes is not a Latin word.
He does not explain how he gets from "peraetumes" to "peractum" (other than saying that some of the ees are supposed to be cees), and peractum does not mean a book for teachers and students, as he claims. Depending on context and grammatical form it has a variety of meanings such as disturbed, harassed, completed, and would not be followed by "con ilaque" (ilaque is not a word in Latin, the only word that's close that is a correct Latin word is "itaque" but then all the ells in the transcript would have to be amended to tees for it to be consistent).
If you glance through his transcript, what you see is a lot of repetitious short syllables with Latin (and French) endings added to make them look like Latin. It's like taking a lot of nonsense syllables in English and adding "-ing" and -ly" and calling it English:
"umlio estoque este iloesesteum feretqueum esaesaus esaus ileumeses"
"etoque estoesaus ilestum iletum esorus etoesanus esto iletois"
"umeteeum oilaum oilum esanus oileteum iloilanus"
"feretestanus estoileteeum etoque liestoeseeesum"
Even if you change some of the ees to cees, there's not a single Latin word in these four lines, except for "esto" or maybe "este" (which is more French than Latin). One correct word every few lines (usually the short words) is not a translation.
To call this Latin stretches credulity pretty far.
