The procedure in either House for ascertaining the general opinion upon any measure or motion differs but slightly in form, and not at all in principle. At the end of every debate the question under discussion is laid before the House by its Speaker or Chairman. This he does by rising in his place and saying, "The question is that ..." (here follows the exact words of the motion). "As many as are of that opinion say 'Aye!'; as many as are of the contrary opinion say 'No!'" (In the Lords the words "Content" and "Not Content" are substituted for "Aye" and "No.") Members or peers thereupon express their views in the required manner, and the Speaker (or Chairman), gathering what is called the "sense of the House" by the volume of sound proceeding from either party, says, "I think the Ayes (or Noes)"—or, in the Lords "the Contents" or "Not Contents"—"have it!"

If the judgment of the Chair be unchallenged, the question is deemed to be resolved in the affirmative or negative, as the case may be, and nothing further remains to be done. Should, however, either party question the correctness of the Chairman's opinion, recourse is had to a division, and certain necessary formalities have to be observed before the matter is definitely settled one way or the other.

When a division is challenged in the House of Commons, the Speaker (or Chairman) orders the Sergeant-at-Arms to "Clear the lobby," and the tellers' doors leading from the lobbies, as well as the door leading from the Central Hall, are immediately locked. After the lapse of two minutes, during which the loud division-bells are set ringing all over the building to summon breathless members to the Chamber, the question is again put from the Chair. If once more challenged, the Speaker names two members of either party to act as "tellers." Should no one be found willing to undertake this duty, a division cannot take place, and the Speaker declares that the "Noes" have it. If, however, tellers are duly appointed, they take their place at the exit doors leading from the two lobbies, which are now unlocked. After another interval, this time of four minutes' duration, the doors leading from the House to the lobbies are locked. Meanwhile, all members who wish to vote have left the Chamber, and are streaming through their respective lobbies, where their names are recorded by clerks, while the tellers count them as they pass through the lobby doors.

In the old days of St Stephen's Chapel, the "Ayes" used to remain in the House, while the "Noes" withdrew, and were counted on their return. This practice led to endless difficulties, many members refusing to go out for fear of losing their seats, while others were forcibly detained by their friends. In Elizabeth's time, Sir Walter Raleigh admitted that he often held a fellow-member by his sleeve, and others were accused of pulling each other back, as Cecil said, "like a dog on a string."[401] Later on, it was decided that members who gave their votes for the introduction of "any new matter" should alone withdraw, while the votes of those who remained behind were recorded. This system also had its disadvantages. In 1834, for instance, when a certain Whig member, Colonel Evans, fell asleep in one of the side galleries during a division, he woke to find that he had been counted among the Tories, much to his disgust. Finally, two years later, the practice of clearing the House altogether for a division was first instituted, and continued in force until the establishment of the modern method in 1906.[402]

When all members who desire to vote have filed through the lobbies, and are once more reassembled in the House, the four tellers advance together to the Table. The senior teller of the party having a majority, walks on the right, bearing in his hand a slip of paper, on which are written the numbers of the division. By the position of the teller it is thus possible to gauge the result of a division before it has been officially announced, and his advance to the Table in the place of honour is usually the signal for an outburst of cheering from his own victorious party. He proceeds to report the result of the division to the Clerk at the Table, who writes the numbers on a piece of paper, which he hands back to him. This the teller passes to the Speaker, who, in turn, announces the numbers to the House. The doors are then unlocked, and the division is at an end.

On one famous occasion the tellers failed to agree in their reports of the figures. This happened on May 10, 1675, when the House in Committee had divided on a motion with regard to the English regiments serving in the French army. The tellers' difference of opinion gave rise to a scene of great confusion, during which one member spat in another's face, and a free fight would probably have ensued but for the sudden arrival of the Speaker.

The amount of time spent in dividing has always been a source of annoyance to earnest politicians, more especially when divisions are made use of as a recognised form of obstruction, and the progress of parliamentary business thereby much impeded. In 1902, to name a recent example, the opponents of the Deceased Wife's Sister Bill, which had already passed a Second Reading, deliberately walked so slowly through the lobbies during four divisions that there was no time left to move that it should be sent to a Grand Committee. Members naturally grudge the precious hours wasted in trudging through the lobbies; but it seems impossible to invent any scheme that shall further expedite matters, the present system being apparently as perfect as the mind of man can devise.[403]

When a division is called in the House of Lords, the procedure is very similar in character to that of the Commons. The Chancellor (or Lord on the Woolsack) orders strangers to withdraw by saying, "Clear the bar!" and the Clerk of the Parliaments thereupon turns a two-minute sand-glass.

When the sand has run out of the glass, the doors are locked, and the question is once more put to the House. If the Lord Chancellor's decision is challenged he at once says, "the 'Contents' will go to the right by the Throne, and the 'Not Contents' to the left by the bar." Each party then passes through its own lobby, the "Contents" re-entering the House on the right of the bar, the "Not Contents" through the door on the left of the Throne, their votes being duly recorded by clerks in the lobbies. The subsequent procedure resembles that in vogue in the Lower House.

Until 1857, when the present system was adopted, the "Contents" remained within the bar, while the "Not Contents" went below the bar. Peers, who through infirmity, or other causes, are disabled from leaving the House, may by its permission be "told" in their seats, and those who do not wish to vote at all are allowed to go within the railings on the steps of the Throne.
