Notes: Paper covers (one of two formats) "Also issued in Cloth, price 2s." This is the source edition for Project Gutenberg Ebook #17508 (see). Uncertain size • WorldCat record OCLC 154710684 reports 18cm. So does OCLC 28435009, for the original of a microfilm copy. • OCLC 1947507 and HathiTrust reports 19cm, perhaps both catalogued by Harvard University. Thus ISFDB format in paper covers is uncertain, pb or tp? HathiTrust Digital Library provides full view of one copy, evidently library bound as containing the original covers (images 7-8, 193-94, with inside covers blank): -- title page There is one interior illustration, p96, likely by Wells. (Perhaps the front cover, too.) There is no preface. For the original 1898 preface see parent nonfiction record.
