Now this Jonathan Hulls was the great grandfather of a man of the same name, now residing in Campden; so that if there be any truth in the tradition, the application of steam power to the propulsion of hulls must be long prior to the time of _Watts his name!_ Can any reader of NOTES AND QUERIES throw any light on the inventions of this man Hulls? NOCAB. _Mythology of the Stars._--I want (in perfect {24} ignorance whether there is such a book) a "Mythology of the Stars." Considering how often persons of sound mind express an enthusiasm for the celestial bodies, and exclaim, of clear night, that the stars are the poetry of Heaven, it is wonderful how little most of us know about them. Nine out of ten educated persons would be quite unable to do more than point out the Great Bear and North Star. If there is not, there _ought_ to be, some collection of the nomenclature and mythological history of the heavens, with a familiar treatise on astrology ancient and modern. The Chaldeans, Egyptians, Grecians, Arabs, Celts, and Norsemen, must have had names and stories, whose relation (both in itself and to one another) would make a very pretty volume either of poetry or prose. Perhaps some of your readers may be able to inform me of such a work, or where detached masses of the information I want could be found. G.I.C. _Sword of William the Conqueror._--Can any one inform me where is the sword of William the Conqueror? It was kept in Battle Abbey till the dissolution, and then taken to Sir John Gage's house at Firle, as it is said. P. _Neville Family._--Will any of your correspondents inform me what family of the Nevilles were connected by marriage with the Fleetwoods or Cromwells? In a collateral note in my family pedigree, I find it stated, that Sarah Neville (who married Thomas Burkitt, in 1683) was cousin to General Charles Fleetwood, who married Bridget Cromwell, daughter of the Protector; and, on the cover of a book, I find written-- "My Cozen Fleetwood he gave me this book.--Sarah Burkitt, 1684." I have also traditional testimony in possessing a valuable cabinet, known us "the Fleetwood;" and a portrait of the above Bridget Cromwell; both of which have been preserved in the family for more than a century and a half, and supposed to have passed into their possession by the marriage of Sarah Neville. A.H.B. Clapham, Jan 1. 1851. _Difformis, Signification of._--Can any of your classical readers refer me to a competent source of information with regard to the signification of the word _difformis_, which is repeatedly to be met with in the writings of Linnaeus, and which I cannot find recorded in _Ducange_, _Facciolati_, or any of our ordinary Latin dictionaries? TYRO. Dublin. _Lynch Law._--What is the origin of this American phrase? J.C.R.
