Some context: Alexander Bell was born in Edinburgh, Scotland, on March 3, 1847. The family home was at 16 South Charlotte Street, and has a stone inscription marking it as Alexander Graham Bell's birthplace. He had two brothers: Melville James Bell (1845-70) and Edward Charles Bell (1848-67), both of whom would die of tuberculosis. His father was Professor Alexander Melville Bell, a phonetician, and his mother was Eliza Grace (nee Symonds).
By 1874, Bell's initial work on the harmonic telegraph had entered a formative stage, with progress made both at his new Boston "laboratory" (a rented facility) and at his family home in Canada a big success. While working that summer in Brantford, Bell experimented with a "phonautograph", a pen-like machine that could draw shapes of sound waves on smoked glass by tracing their vibrations. Bell thought it might be possible to generate undulating electrical currents that corresponded to sound waves. Bell also thought that multiple metal reeds tuned to different frequencies like a harp would be able to convert the undulating currents back into sound. But he had no working model to demonstrate the feasibility of these ideas.  In 1874, telegraph message traffic was rapidly expanding and in the words of Western Union President William Orton, had become "the nervous system of commerce". Orton had contracted with inventors Thomas Edison and Elisha Gray to find a way to send multiple telegraph messages on each telegraph line to avoid the great cost of constructing new lines. When Bell mentioned to Gardiner Hubbard and Thomas Sanders that he was working on a method of sending multiple tones on a telegraph wire using a multi-reed device, the two wealthy patrons began to financially support Bell's experiments. Patent matters would be handled by Hubbard's patent attorney, Anthony Pollok.  In March 1875, Bell and Pollok visited the scientist Joseph Henry, who was then director of the Smithsonian Institution, and asked Henry's advice on the electrical multi-reed apparatus that Bell hoped would transmit the human voice by telegraph. Henry replied that Bell had "the germ of a great invention". When Bell said that he did not have the necessary knowledge, Henry replied, "Get it!" That declaration greatly encouraged Bell to keep trying, even though he did not have the equipment needed to continue his experiments, nor the ability to create a working model of his ideas. However, a chance meeting in 1874 between Bell and Thomas A. Watson, an experienced electrical designer and mechanic at the electrical machine shop of Charles Williams, changed all that.  With financial support from Sanders and Hubbard, Bell hired Thomas Watson as his assistant, and the two of them experimented with acoustic telegraphy. On June 2, 1875, Watson accidentally plucked one of the reeds and Bell, at the receiving end of the wire, heard the overtones of the reed; overtones that would be necessary for transmitting speech. That demonstrated to Bell that only one reed or armature was necessary, not multiple reeds. This led to the "gallows" sound-powered telephone, which could transmit indistinct, voice-like sounds, but not clear speech.
What happened at that meeting?
A: asked Henry's advice on the electrical multi-reed apparatus that Bell hoped would transmit the human voice by telegraph.

Some context: The Hereditary peers form part of the peerage in the United Kingdom. As of 1999, there were about 800 peers holding titles that could be inherited. Not all hereditary titles are titles of the peerage. For instance, baronets and baronetesses may pass on their titles, but they are not peers.
The ranks of the Peerage in most of the United Kingdom are, in descending order of rank, duke, marquess, earl, viscount and baron; the female equivalents are duchess, marchioness, countess, viscountess and baroness respectively.  In the Scottish peerage, the lowest rank is lordship of Parliament, the male holder thereof being known as a lord of Parliament. A Scottish barony is a feudal rank, and not of the Peerage. The barony by tenure or feudal barony in England and Wales was similar to a Scottish feudal barony, in being hereditary, but is long obsolete, the last full summons of the English feudal barons to military service having occurred in 1327. The Tenures Abolition Act 1660 finally quashed any remaining doubt as to their continued status.  Peerage dignities are created by the Sovereign by either writs of summons or letters patent. Under modern constitutional conventions, no peerage dignity, with the possible exception of those given to members of the Royal Family, would be created except upon the advice of the Prime Minister.  Many peers hold more than one hereditary title; for example, the same individual may be a duke, an earl, a viscount and a baron by virtue of different peerages. If such a person is entitled to sit in the House of Lords, he still only has one vote. However, until the House of Lords Act 1999 it was possible for one of the peer's subsidiary titles to be passed to his heir before his death by means of a writ of acceleration, in which case the peer and his heir would have one vote each. Where this is not done, the heir may still use one of the father's subsidiary titles as a "courtesy title", but he is not considered a peer.
Are there other titles or ranks?
A:
the female equivalents are duchess, marchioness, countess, viscountess and baroness respectively.
