Typo Man Salutes Two Eagle-Eyed Readers

C. P. and J.I.O. warrant my gratitude for catching errors.  Platonizer that I am,  my mind goes directly to the trans-sensible sense and is appropriately inattentive to its mere material embodiment.  I try to catch all my typographical errors but I am regularly surprised at how many I miss.

I probably missed one in the line just written. 

And damned if I didn't find one, after writing the last sentence, a typo now duly corrected.
