CclxiV LIFE OF BACON. 



The NOVUM ORGANUM is the next subject of consider 

 ation. It thus opens : 



your hand on the top, it will presently burn the hand. 

 Invert the iron, and place the hand on the ground, to 

 ascertain whether heat is produced as rapidly by descent 

 as by ascent. 



VARIATION is either of the matter, as the trying to 

 make paper of woollen, as well as of linen; or of the 

 efficient, as by trying if amber and jet, which when rubbed, 

 will attract straw, will have the same effect if warmed at 

 the fire; or of the quantity, like JEsop s huswife, who 

 thought that by doubling her measure of barley, her hen 

 would daily lay her two eggs. 



TRANSLATION is either from nature to nature, as Newton 

 translating the force of gravity upon the earth to the celes 

 tial bodies; or from nature to art, as the manner of distilling 

 might be taken from showers or dew, or from that homely 

 experiment of drops adhering to covers put upon pots of 

 boiling water; or from art to a different art, as by trans 

 ferring the invention of spectacles, to help a weak sight, to 

 an instrument fastened to the ear, to help the deaf; or to 

 a different part of the same art : as, if opiates repress the 

 spirits in diseases, may they not retard the consumption 

 of the spirits so as to prolong life ; or from experiment to 

 experiment : as upon flesh putrefying sooner in some cellars 

 than in others, by considering whether this may not assist 

 in finding good or bad air for habitations. 



Such are the modes of experimenting by translation,* 



* They may be thus exhibited : 

 1. F nature. 



v 5 To a different art. 



?To a different part of the same art. 



3. From experiment to experiment.
