Peruse or Pervise—Passage in Frith's Works

Your correspondent T.J. rightly conjectured that the *peruse* of a modern reprint of Frith was an error. I have been able since to consult two black-letter editions, and have found, as I suspected, "pervise" and "pervyse." If your same correspondent, or any other, can help me to correct, or to understand another erroneous clause in Russell's edit. of Frith, vol. iii. p. 227., I shall be still further obliged. It is probably meant for some old rule in logic, but is printed there, "Ab inferiori ad suis superius confuse distribue." Foxe, however, has "suum" instead of "suis."
