I. The Divine History of the Genesis of the World, explicated and illus- 

 trated. London, 1670, in 4to. 



This author, not thinking fit to give us his name, takes no small pains to ex- 

 plain in this his book the Genesis of the World, as it is delivered by Moses, es- 

 teemed by him the only true philosopher. 



II. Franc. Travagini, Super Observationibus a se factis tempore ultimorum 

 Terrae-Motuum, ac potissimum Ragusiani, Physica Disquisitio, seu Gyri Terree 

 Diurni Indicium. Lugduni Batavorum, 1669, in 4to. 



This Venetian philosopher acquaints the curious, in this book, with some ob- 

 servations made by himself in two late earthquakes, and by others also in 

 the last about Ragusa, whence he thinks an argument may be drawn to confirm, 

 among other proofs, the diurnal motion of the earth. 



His obseiTations are, that in those earthquakes he found, besides a subsulting 

 perpendicular motion, found by others," a concomitant lateral one, from west to 

 east; which latter he" conceives was not caused by the former, but only disco- 

 vered by it ; just as the progressive motion of a boat, carried with a still stream, 

 is not produced, but only made sensible, from an accidental check, to a person 

 that shall have been put in it asleep, when it was at rest, but awakens, after it 

 was made to swim down a still river; who will think himself unmoved, till the 

 boat meet with some stop, whereby for the time its course will either be hin- 

 dered or disturbed^ and he made sensible of his being in motion. 



He alleges divers other observations, made of rivers, suspended bells, and 

 church lamps, which were all observed by himself and many others, to have 

 likewise the said lateral and vibrating motion. Whereupon he admonishes his 

 readers that they would, on the like occasions, take very particular notice of all 

 the several motions in earthquakes ; and then consider with themselves, whe- 

 ther from such observations universally made, importing that the earth in earth- 

 quakes is vibrated towards the east, and that that vibration cannot proceed from 

 its succussation, (which is only able to cause a perpendicular motion in the
