The Pulse Glass (And the beat of other hearts) - Gillian Tindall

A toy train. A stack of letters. A tiny pulse glass, inherited from her great-great-grandfather, which was used to time a patient's heartbeat before pocket watches... Gillian Tindall, one of our most admired domestic history writers, examines seemingly humble objects to trace the personal and global memories stored within them, and re-animate the ghostly heartbeats of lost lives.
