1. (a)ACircular View from the Balloon at its greatest Elevation, (Page 58.) The Spectator is supposed to be in the Car of the Balloon, suspended above theCenterof the View: lookingdownon the Amphitheatre orwhiteFloor of Clouds, and seeing theCity of Chester, as it appeared throu’ theOpening: which discovers the Landscapebelow, limited, by surrounding Vapour, to something less thantwoMiles in Diameter.

2. (b)The Balloon over Helsbye-Hill in Cheshire, at half past II. on Thursday the 8th of September, 1785. (Page 78.)
It is seen in theSouth-west-Quarter.
The View was taken in ahighField, at the End of Sutton-Causeway.
Helsbye-Hill, tho’ upwards of 600Feet high, appeared from the Car of the Balloon, to be on thesame Levelwith theGrounds below.
3. (c)A Balloon-Prospect from above the Clouds, (Page 154,) orChromaticView of the Country between Chester, Warrington and Rixton-Moss in Lancashire: shewing the whole Extent of the aërial Voyage; with themeanderingTrack of the Balloon throu’ the Air.
4.The Explanatory Print(d), (Page 155:) which elucidates the former by giving the Names of the principal Places mentioned in the Excursion.
N. B.The Circular Viewis seen to the best Advantage, when placedflaton a Table or Chair, andratherin the Shade: the Eye lookingdirectlydown upon the Picture.
Whoever will be at the Trouble of viewingdistinctParts of theBalloon-Prospect, throu’ a very small Opening, made by rolling a Sheet of Paper into the Form of a hollow Tube, and applying it close to either Eye, at the same Time shutting the other; or by looking throu’ the Hand, held a little open, and close to the Eye; may form a very accurate Idea of the Manner, in which theProspect belowwas representedgradually in Succession, to the Aironaut; whose Sight was bounded by a Circularity of Vapour, as in Section79,221.
Place theTopof thecircular view,evenwith theTopof the Page.
The Plate will then lye over at the Bottom, and at therightSide of the Page.
Fold the Bottom up into the Book, even with the Margin: and therightSide in like Manner.
Observe to place theBottomof each of the other Plates, even with theBottomof the Page.
The Plate will then lyeoverat the Top, and at therightSide of the Page.
Fold the Topdown, into the Book,evenwith the Margin: and the right Side, in like Manner.
