This hypertext is a brief review of certain ideas and specific passages from texts cited by the ‘some of the fragments’ passage.

Those passages without a two-letter indication of source (ms/id/sg) are by the pro-author of this hypertext, John Cayley.

The form of linking in this hypertext is experimental and slightly unusual. In part, it is the result of the limitations within basic html and the ‘frames’ facilities initiated by Netscape (where a link in one frame cannot, it seems, update the content of more than one other frame at one time).
