+--------------------------------------+ | | | _The author of this story, being a | | chemist of high standing and an | | excellent mathematician, gives us a | | rare gem in this interplanetary | | tale. For one thing, he suggests an | | interesting use of the action of | | acceleration. In this instalment it | | is made to take the place of gravity | | when the interplanetary vehicle is | | out in open space. In order to get | | the gravity effect, a positive or | | negative acceleration could be given | | out. | | | | This instalment retains its easy | | flow of language and continues to | | develop surprise episodes with a | | remarkable degree of realism._ | | | +--------------------------------------+
