X791' NAPIER's INVENTIOK. 155 



i^5?/r^Z»/;', The invention of a round chariot of tnetai, 

 made of the proof of double mufket, whofe motion Qiall 

 be fuch, that thofe that be within the fanne fliall be more 

 cafy, more light, more fpeedy, and more fafe in battle, 

 than any liitherto contrived. The ufe hereof in mov- 

 ing, is to break the array of the enemies battle, and 

 to make paffage, as alfo iu Haying and abiding within 

 the enemies battle. It ferveth to deftroy the environed 

 enemy, by continual charges and fiiot of the Harque- 

 bufe, through fmall holes, the enemy in the mean time 

 being abafed, and altogether uncertain what defence or 

 purfuit to ufe againft a moving mouth of metal, 



Thefe inventions, befides devices of failing under 

 the water, with divers other devices and ftratagems for 

 harming of the enemies, by the grace of God, and 

 work of expert craftfmen, I hope to perform.
