Page 102 in covenants talks about studing realia. Bottom of the 1st colum, top of the second says..
A collection can be studied as a tractatus, a single object as quality 1, two as quality 2, 4 as quality 3, and so on. Realia collections rarely rise above quality 6 which requires 64 excelent specimens
I'm not seeing the pattern here to get from 4 giving quality 3 to 64 giving quality 6. Can anyone help me out?
