“More daring than Poe’s ‘Narrative of Arthur Gordon Pym of Nantucket’ is Mr. Mastin’s romance of Antarctic adventure; for Poe, having introduced a giant ‘of the perfect whiteness of the snow,’ regrets the loss of his crowning chapters. Certainly, if the matter which they contained ‘relative to the Pole itself, or at least to regions in its very near proximity,’ was as sensational as ‘The Immortal Light,’ the loss is deplorable.... The story is wildly improbable, but confronts incredulity with a considerable display of scientific detail. A strong religious feeling animates the last part of the book.”—_Athenæum._ “To say that this is a really clever story is but bestowing on its author, Mr. John Mastin, praise which is well deserved.... The experiences of the explorers in conquering the ice barrier of the South, as told by the writer, makes delightful reading. Although the story is fiction unadulterated, it is of absorbing interest, and even the most fastidious reader could not fail to find some charm in a perusal of its pages.... That the bounds of possibility have been far overstepped is only natural.... But with rare literary skill the author discounts these by the many charms of a story which is well told. The character studies are good, and many excellent word-pictures are painted in glowing colours by the picturesque pen of the author.”—_Western Daily Press._ “The book is exceedingly clever and up to date.”—_Glasgow Herald._ “What Jules Verne did with the science of the seventies and eighties, Mr. Mastin does for the science of to-day.... Youth, if it has a scientific turn of mind and some imagination, will revel in this book.... We can heartily congratulate him on the imaginative power which his book displays. That never flags, and he carries us on from wonder to wonder as if he need never stop.”—_Sheffield Telegraph._ “Some of the speculations on the wonders of life and the possibilities of science are broad, ingenious, and fascinating.... From telepathy to telescopes which see everywhere, and from rides on ether to steel that will line coats, Mr. Mastin ranges with plausible certitude.... ‘The Immortal Light’ is an amazing book.”—_Sheffield Daily Independent._ “The plot is exciting.”—_Morning Leader._ “Mr. Mastin is thoroughly up to date in his paraphernalia.”—_Yorkshire Post._ “But the work, while an intelligent boy could not read it without a keen enjoyment, has a scientific weight, a plausibility of inductive and deductive reasoning upon a basis of natural law, which takes it well out of the category of the merely fantastic.”—_Scotsman._ “There are minute descriptions of all the wonderful inventions made by a strange race which talks Latin and lives underground. The author is evidently a learned scientist and ... quite as accurate as Jules Verne.... He possesses a vivid imagination.... I may safely recommend the story.”—_John Bull._ ————————————————————————————————————————————————————————————————————————
