    Interesting Abigail-II, I will add that list to the list I have in my own notes. Typesetting and Typography have been my passion since teenage years. Whilst I claim no authority for this list, other than the fact that I have it, it might seem that the namings of the Anglo-Saxon point sizes use a different spelling for Pearl.
    Pearl                 5 point 
    Nonpareil             6 point 
    Minion                7 point 
    Brevier               8 point 
    Bourgeois             9 point 
    Long Primer          10 point 
    Small Pica           11 point 
    Pica                 12 point 
    English              14 point 
    Two Line Brevier     16 point 
    Great Primer         18 point 
    Paragon              20 point 
    Double small Pica    22 point 
    Double Pica          24 point 
    Double English       28 point 
    Four line Brevier    32 point 
    Double Great Primer  36 point 
    Canon                48 point 
    
    Of course 1 perl = 5 * 0.3759mm = 1.8795mm (the Didot point is 1/72 of the French Royal Inch which was 27.07mm) whereas...

    1 pearl = 5 * 0.3514598mm = 1.7573mm (The ATA or Anglo-Saxon point is a little smaller).

    Of course, the now common in digital typesetting Postscript point is 1/72 of an inch, or approximately 0.3528mm, just to confuse the issue.
