AN EPISTLE TO MY READERS.
I Must advertise my Readers that though I have writ difserent wayes of one and the same subject, yet not to obstruct, crosse, or contradict; but I have used the freedom, or taken the liberty to draw seve∣ral works upon one ground, or like as to build several rooms upon one foundation, likewise my desire was, to expresse the several works that several motions make in printed figures, that the sense of my opinions might be explained to the eye, as well as to the ear, or conceivements of my Readers; but by reason the Painters and Cutters in this Country cannot speak, nor understand English, nor I any other Language; which reason per∣swaded me to let my Book be Printed without them, for though I might have had such an Interpreter that could expresse grosse ma∣terial subjects, yet none that were so learned in both Languages, as to expresse, and instruct them to expresse by their art the figures of the fine, curious, subtil, and obscure motions in nature, and to have them all done would have rather puzled my Readers, and confoun∣ded the sense of my opinions, then any wayes have advantaged the one, or informed the other.
Wherefore I must intreat my Readers to take a little more paines, and care in the reading, and considering part.
