Similarly the telegraph is not to be regarded as the work of any one mind, but of many, and during a long course of years. Because at length the final seedling is obtained, are we to overlook the antecedent varieties from which it was produced, and without which it could not have existed? Because one inventor at last succeeds in putting the telegraph in operation, are we to neglect his predecessors, whose attempts and failures were the steps by which he mounted to success? All who have extended our knowledge of electricity, or devised a telegraph, and familiarised the public mind with the advantages of it, are deserving of our praise and gratitude, as well as he who has entered into their labours, and by genius and perseverance won the honours of being the first to introduce it.
