As soon as possible after the risingof Parliament, we intend

to exhibit in the Spectator,.

A PARLIAMENTARY BAROMETER.

This is an instrument whereby the fidelity and integrity of the Members of the First Reformed House of Commons may be ascertained at a glance. By means of graduated columns, marginal indications, and certain arithmetical quicksilver, the Constituency of any city, county, district, or borough, may learn without trouble, on applying their Member's name to the test, how far he has adhered to or de- parted from his promises and their expectations. The instrument will be so con- trived as to measure the sum total of any Member's fidelity, and also to indicate the course he has taken upon any particular question or subdivision of his duty. A- Key will accompany the PARLIAMENTARY BAROMETER; showing the nature and importance of all the great questions that have been discussed in the present Session,with a list of those to which Members had pledged their faith. On turning from this Key to the Barometer, it will be instantly seen how the pledge has been redeemed, and generally, how high the individual stands, according to this new and useful method of gauging the political atmosphere.

The day of publication will be fixed in another notice. In the mean time, all who have any information to offer on the respective compacts between Constituencies and Members, whether by direct pledges or otherwise, will be pleased to trans- mit their communications without delay, properly authenticated, and the postage paid.

As a specimen of the sort of information we want, we subjoin an extract from one of the contributions we have already received in consequence of the former insertion of this notice. •
