Lecture on Stephen Gray's discoveries in electricity

A lecture at the Charterhouse, London on Stephen Gray's discoveries in electricity. In the early eighteenth century, Gray demonstrated that charges of electricity could be conducted by some materials for distances as great as 765 feet, while others did not conduct electricity at all. Eventually, he was able to send charges through 88 metres of wire suspended on silken threads to operate an electroscope - an instrument used to detect static electricity. By sending an electrical signal from one place to another, Gray established the basic principle of the electric telegraph.

Letter from Lt. Colonel Richardson, dog trainer Featured Print

Letter from Lt. Colonel Richardson, dog trainer

Letter from the renowned dog trainers Lt. Colonel Edwin Hautenville Richardson to the Royal Society of Arts, confirming that he would give a lecture for them on the subject of dogs in peace and war. He also makes suggestions about other talks he gave. Richardson was well known for providing guard, sentry and police dogs and lobbied for dogs to be used more widely at the front during the First World War in line with other countries. Eventually, he was asked to set up the British War Dog School at Shoeburyness (later it moved to Lyndhurst in the New Forest) where hundreds of dogs were trained to act as ambulance, sentry and, in particular, messenger dogs with great success. Date: 1924
