The end

As to Miss Violet Hunter, my friend Holmes, rather to my disappointment, manifested no further interest in her when once she had ceased to be the centre of one of his problems, and she is now the head of a private school at Walsall, where I believe that she has met with considerable success.

THE END

Life preserver

But when I gave him every particular that had occurred, he tried to bluster and took down a life-preserver from the wall. I knew my man, however, and I clapped a pistol to his head before he could strike.

(Adventure XI, pg. 160)

“The “life-preserver” consists of a stout piece of cane about a foot long, with a ball of five or six ounces of lead attached firmly to one end by catgut netting, whilst the other end is furnished with a strong leather or catgut loop to go round the wrist and prevent the weapon flying from or being snatched from the hand.

Pistol

An ordinary man could not do it. Now, what do you think would happen if I did break it, Mr. Holder? There would be a noise like a pistol shot.

Jezail

I had remained indoors all day, for the weather had taken a sudden turn to rain, with high autumnal winds, and the Jezail bullet which I had brought back in one of my limbs as a relic of my Afghan campaign throbbed with dull persistence.
(Adventure X, pg. 131)

In the novel, this is the weapon that would have woulded Dr. Watson during his military service in Afghanistan.

About the weapon

Fire engine

The station-master had not finished his speech before we were all hastening in the direction of the fire. The road topped a low hill, and there was a great widespread whitewashed building in front of us, spouting fire at every chink and window, while in the garden in front three fire-engines were vainly striving to keep the flames under.

(Adventure IX, pg. 130)

Horse pulled steam powered fire pump from the early 1900.

Hydraulic stamping machine / Hydraulic press

"'I say a night's work, but an hour's would be nearer the mark. I simply want your opinion about a hydraulic stamping machine which has got out of gear. If you show us what is wrong we shall soon set it right ourselves. What do you think of such a commission as that?'

(Adventure IX, pg. 122)

This we have now been doing for some time, and in order to help us in our operations we erected a hydraulic press.

(Adventure IX, pg. 123)

A huge hydraulic press designed by Stevenson that had lifted the metal tubes of a bridge at Bangor, was one of the exhibits in the Great Exhibition of 1851 in the Chrystal palace.

Kettle

Then suddenly another sound became audible--a very gentle, soothing sound, like that of a small jet of steam escaping continually from a kettle.
(Adventure VIII, pg. 116)

Early kettles would have been made of iron and by the 19th century copper was a common material. In the mid 1900s alluminum and stainless steel kettles started to be manufactured.

Bell pull

"Indeed, it seemed unnecessary to put so nice a bell-pull there. You will excuse me for a few minutes while I satisfy myself as to this floor."

(Adventure VIII, pg. 111)

The bell pull is one element of a complex interior mechanical network which typically in Victorian times involved a range of bell pulls in different rooms; moreover, these bell connections link to a central bank of bells in a room where servants would await commands.

University medical degree

The last squire dragged out his existence there, living the horrible life of an aristocratic pauper; but his only son, my stepfather, seeing that he must adapt himself to the new conditions, obtained an advance from a relative, which enabled him to take a medical degree and went out to Calcutta, where, by his professional skill and his force of character, he established a large practice.

Vitriol

There have been two murders, a vitriol-throwing, a suicide, and several robberies brought about for the sake of this forty-grain weight of crystallised charcoal.

(Adventure VII, pg. 92)

Vitriol, or sulfuric acid, was known since ancient times by islamic alchimists around 900 AD. In 1831, British vinegar merchant Peregrine Phillips patented the contact process, which was a far more economical process for producing sulfur trioxide and concentrated sulfuric acid. Today, nearly all of the world's sulfuric acid is produced using this method.

Gas

These are the more patent facts which are to be deduced from his hat. Also, by the way, that it is extremely improbable that he has gas laid on in his house."

(Adventure VII, pg. 90)

All the energy used to light the streets and houses came from gas.

Forceps

A lens and a forceps lying upon the seat of the chair suggested that the hat had been suspended in this manner for the purpose of examination.

Instrument's description

Wax vestas (matches)

He is a professional beggar, though in order to avoid the police regulations he pretends to a small trade in wax vestas.

(Adventure VI, pg. 77)

In 1832, William Newton patented the "wax vesta" in England. It consisted of a wax stem that embedded cotton threads and had a tip of phosphorus. Variants known as "candle matches" were made by Savaresse and Merckel in 1836.

Dogcart

"Now, Watson," said Holmes, as a tall dog-cart dashed up through the gloom, throwing out two golden tunnels of yellow light from its side lanterns. "You'll come with me, won't you?"

Oil lamp

Ordering my cab to wait, I passed down the steps, worn hollow in the centre by the ceaseless tread of drunken feet; and by the light of a flickering oil-lamp above the door I found the latch and made my way into a long, low room, thick and heavy with the brown opium smoke, and terraced with wooden berths, like the forecastle of an emigrant ship.

Lighthouse

"I didn't know what to do, so I came straight to you." That was always the way. Folk who were in grief came to my wife like birds to a light-house.

Steamboats

It is conjectured that he may have been hurrying down to catch the last train from Waterloo Station, and that in his haste and the extreme darkness he missed his path and walked over the edge of one of the small landing-places for river steamboats.
