perigaeum. For example, 1. That famous inundation, mentioned before out 

 of Holinshed, 1250, Oct. 1. was, when the moon was in perigaeo, as appears 

 by calculation. — 2. 1530, Nov. 5. That inundation on which was made the 

 distich; 



Anno ter deno post sesquimille, Novembris 

 Quints, Stat salsis Zelandia tota sub undis ; 

 was when the moon was in perigaeo. — 3.( Jan. 13, 1551-2, the sea (says 

 Michell in his chronicle) broke in at Sandwich, and overflowed all the marshes 

 thereabout, and drowned much cattle : the moon in perigaeo. — 4. 1570, Nov. 

 1, was a dreadful flood at Antwerp, and on all the coasts of Holland, that 

 made infinite spoil: the moon in perigaeo. — 5. l600, Dec. 8, above-mentioned: 

 the moon in perigaeo. — 6. ltio6-7, Jan. 20, was a great inundation in the Se- 

 vern, mentioned in Howes's chronicle, that did much hurt in Somersetshire, 

 Glocestershire, &c. the moon in perigaeo. — 7- 1555, Sept. 30, the moon was 

 in perigaeo. — 8. l643, Jan. 23, n. s. (says a little Low Dutch chronicle that I 

 have) was a terrible high water-flood in Friesland, &c. whereby much hurt 

 was done to the dykes ; and at Gaes by Haerlingen the dead bodies streamed 

 out of the earth: the moon in perigaeo. — Q. l651, Feb. 23, n. s. (says the 

 same chronicle) was St. Peter's high flood, whereby much hurt was done to 

 the dykes in Friesland, Embderland, and elsewhere, and not far from Dockum 

 by Oudt-woudumer-ziil is a breach of 42 roods long broken in the dyke : the 

 moon in perigaeo. — 10. Aug. 2, 1657, at Feversham was a very high spring 

 tide, and yet the wind was at south-east ; which deads the tides there : the 

 moon in perigaeo. — 11. Aug. 22, 1658, at Feversham was a very high tide in 

 the afternoon, though the wind was southerly, and blew very stiff', which the 

 seamen there wondered at : the moon in perigaeo. — 12. 1661, upon Michael- 

 mas day was a great overflowing of the Severn, that it drowned the low 

 grounds lying by it: the moon in perigaeo. — 13. The scheme of the weather, 

 printed in the history of the R. S. tells us, that May 24, 1663, was a very 

 great tide at London. But it tells us withal that the same day the moon was 

 in perigaeo. — 14. Sept. 1, 1669, at Weymouth I observed a very high tide; 

 and so did several seamen in that town, who wondered at it, the weather be- 

 ing very calm and that little wind that was being at north-east, which uses to 

 contribute nothing at all to the tides in that haven : the moon in perigaeo. 



F'urther, what inclines me to believe that the perigaeosis of the moon is of 

 some concernment in this matter, is, because it is a maxim among our Kentish 

 seamen, that they never have two running spring tides (as they call them) to- 

 gether, but that the next spring tide, after a high running spring, is propor- 

 tionably weak and slack ; which, if true, is very correspondent to my opinion.
