I have had variable success with my mail client preserving pdf images,  
but If it turns out that these are unreadable then I can affirm that  
the example described matches the ?colon description very well and one  
only needs to search Google Scholar for copies of that classic work  
that appears here  in full text albeit a dirty image:
