Tuba Stentoro-Phonica an Instrument of Excellent Use, as Well as at Sea as at Land

Here are some pictures from our copy of Sir Samuel Morland’s Tuba Stentoro-Phonica an Instrument of Excellent Use, as Well as at Sea as at Land: Invented and Variously Experimented in the Year 1670 and Humbly Presented to the Kings Most Excellent Majesty Charles II, in the Year 1671.  Morland (1625–1695), a diplomat and inventor, had been on the side of the Commonwealth but when he became disillusioned, he became a double agent, supporting the Restoration.

He is credited with inventing the speaking trumpet, an early megaphone.
