152 PREFACE TO THE 



superficie et confirms coeli, et aeris regione media quam 

 vocant ; Etiam fluxus maris tarn regularis est quam 

 motus lunae. 



De motu autem animali, et de eo motu qui ad sen- 

 sum peragendum requiritur, non inquirimus, sed eum 

 sui juris facimus et emancipamus ut seorsim et prin- 

 cipaliter inquiratur. 



Motus autem animales quatenus ad coliibitionem et 

 participationem manifestam motuum cgeterorum com- 

 prehendimus, ut saltum, sanguinis per venas ascen- 

 sionem, etc. 



Motus autem impressionis sive signaturse quas incor- 

 porege sunt tamen ob spatiorum sive locorum Mutatio- 

 nes comprehendimus, ut in sonis, visibilibus, attractioni- 

 bus sive coitionibus ; calorem tamen et frigus omnino 

 emancipamus ob dignitatem et multiplicem usum, et 

 de illis seorsim et principaliter inquiri volumus. 



Nee motum generationis vitalis expedimus, sive as- 

 similationem magnam, sed et hunc emancipamus. 



Carta Articulorum. 



First to enquire the several kinds or diversities of 



motion. 

 Then what bodies or subjects are susceptible of every 



kind and what not, and what have them in 



strength and what more obscurely, and what have 



them more familiarly and what more rarely. 

 Then the comparisons of the forces of every motion, 



and which is predominant one over the other, and 

 . which is absolute and never falsified, if any such 



be ; and how they evade and shift each nature 



of motion to do his part. 1
