1851 Great Exhibition: Official Catalogue: Class X.: G. Moubray Gilbert
234. GILBERT, G. MOUBRAY, Ealing — Proprietor.
Patent portable celestial and terrestrial globes, inflated with atmospheric air, manufactured of superior tissue paper. The celestial globe is particularly adapted for the use of lecturers on astronomy: a view of the stars in their true position may be thus obtained.
The terrestrial globe is inflated by means of an air- pump, or simple movement of the hand.
Charvolaut or carriage drawn by kites.
[A view of the stars in their true position, relatively to each other and to the observer, can only be obtained by placing the eye inside of the celestial globe at its centre. A view of the countries of the earth in their true position can only be obtained by placing the eye outside of the terrestrial globe, at an infinite distance but this being impossible, the greater the distance, the more accurate is the view.]
