"I see no possible objection to your now publishing the deferred "scrap" if you yourself approve of what is said in it in favour of quaternions. I think you are right in your use of the word "Volapuk," but I don't think you should confine it to the vector part of quaternions. The whole affair has in respect to mathematics a value not inferior to that of "Volapuk" in respect to language."
