Description: After the events related in The Time Machine, the Time Traveller (his first name, Moses, is given in the novel but applied to the Time Traveller's younger self) prepares, in 1891, to return to the year 802,701 and save Weena, the Eloi who died in the fire with the Morlocks. He reveals that the quartz construction of the time machine is suffused with a radioactive substance he calls Plattnerite for the mysterious benefactor who gave him the sample to study twenty years earlier, in 1871.
