298 CHEMISTRY. 



BOYLE (ROBERT). Tracts, containing new experiments, touching the 

 relation between flame and air, and about explosions ; an hydrostatical 

 discourse occasion'd by some objections of Dr. H. Moore, to which is 

 annex't an hydrostatical letter about the way of weighing water in 

 water ; new experiments of the position and relative levity of bodies 

 under water ; of the air's spring of bodies under water ; about the dif- 

 fering pressure of heavy solids and fluids ; 6 pts. in 1 vol. 8 London, 

 1672. 



. Tracts containing suspicions about some hidden qualities of the air, 



with an appendix touching celestial magnets (observations about the 

 growth of metals in their ore exposed to the air ; some additional ex- 

 periments relating to the suspicions about the hidden qualities of the air) ; 

 animadversions upon Mr. Hobbes's Problemata de vacuo ; a discourse 

 of the cause of suction by attraction* (new experiments about the pre- 

 servation of bodies in vacuo Boyliano) ; 6 pts. in 1 vol. 8 London, 

 1675 [1674]. 



* So printed ; but in manuscript is substituted attraction by suction. 



Tracts of a discovery of the admirable rarefaction of the air ; new 



observations about the duration of the spring of the air ; new experi-

 nical engins ; the admirable differing extension of the same quantity of 

 air rarefied and compressed. 4- London, 1671.
