Little Dorrit by Charles Dickens

Mr Henry Gowan and the dog were established frequenters of the cottage, and the day was fixed for the wedding. There was to be a convocation of Barnacles on the occasion, in order that that very high and very large family might shed as much lustre on the marriage as so dim an event was capable of receiving.

To have got the whole Barnacle family together would have been impossible for two reasons. Firstly, because no building could have held all the members and connections of that illustrious house. Secondly, because wherever there was a square yard of ground in British occupation under the sun or moon, with a public post upon it, sticking to that post was a Barnacle. No intrepid navigator could plant a flag-staff upon any spot of earth, and take possession of it in the British name, but to that spot of earth, so soon as the discovery was known, the Circumlocution Office sent out a Barnacle and a despatch-box. Thus the Barnacles were all over the world, in every direction--despatch-boxing the compass.
