324 PHILOSOPHICAL TRANSACTIONS. [aNNO 1733. 



Then follows a letter from Mr. Stibbs, stating the number of men seized with 

 the jail fever, and what proportion they bore to the whole number, employed by 

 him in setting up the ventilator in Newgate. 



In this letter Mr. Stibbs gives the names of all the workmen that worked on 

 the ventilator in Newgate, and how many had the jail distemper. One of the 

 principal men, whose name was Wilmot, died, and all the rest recovered. He 

 was informed by the person, whose name was Jac;kson, that took care of the 

 windmill and ventilators, that but J person had died within 1 months; whereas 

 before the ventilator was used, there died 6 or 7 in a week; so that it appeared 

 very plain, that the ventilator caused the foul stagnated air to circulate, and- 

 thereby consequently was drawn out of the several wards. 



Mens names: Mr. Sewel,* Mr. Hand,* Mr. Wilmot* (died), Mr. Letts, 

 Mr. Chaddock,* Mr. Rust,* Mr. Morris, Mr. Bates, Mr. Thompson,* Bur- 

 ton, apprentice, Dobie,* ditto. 



N. B. All those marked * had the jail distemper. 



VII. Of the great Alterations which the Islands of Scilly have undergone since 

 the Time of the Ancients, who mention them, as to their Number, Extent, 

 and Position; in a Letter to the Rev. Thomas Birch, D. D. Seer. R. S. by the 

 Rev. Mr. Wm. Borlase, M.'A., F. R. S. p. 55. 



The inhabitants of these isles are all new-comers; not an old habitation worth 

 notice; nor any remains of Phenician, Grecian, or Roman art, either in town, 

 castle, port, temple, or sepulchre. All the antiquities here to be seen are of 

 the rudest Druid times; and, if borrowed in any measure from those eastern 

 traders before-mentioned, were borrowed from their most ancient and simple rites. 

 We are not to think, however, but that Scilly was really inhabited, and as 

 frequently resorted to anciently, as the old historians relate. All the islands 

 (several of which are now without cattle or inhabitant) by the remains of hedges, 

 walls, foundations of many contiguous houses, and a great number of sepulchral 

 barrows, show that they have been fully cultivated and inhabited. That they 

 were inhabited by Britons, is past all doubt, not only from their vicinity to Eng- 

 land, but from the Druid monuments; several rude stone pillars; circles of 

 stones erect; kist-vaens without number; rock-basins ; tolmens; all monuments 

 common in Cornwall and Wales, and equal evidences of the antiquity, religion, 

 and origin of the old inhabitants. They have also British names for their little 

 islands, tenements, and creeks. 



How came these ancient inhabitants then, it may be asked, to vanish, so as 

 that the present have no pretensions to any affinity or connection of any kind 

 with them, either in blood, language, or customs ? How came they to disappear, 

 and leave so few traces of trade, plenty, or arts, and no posterity, that we can
