An easie way to take the naturall, and lively shape of the leafe of any hearbe or tree, which thing passeth the Art of man to imitate with Pen or Pensill.
First take the leafe that you would have, and gently bruise the ribs and veines on the backe side of it, afterwards wet that side with Linseed-oyle, and then presse it hard upon a peece of cleane white paper, and so you shall have the perfect figure of the said leafe, with every veine thereof, so exactly exprest as being lively coloured, it would seeme to bee truly naturall, by this we learne, that Nature being but a little adjuvated or seconded with Art, can worke wonders.
Now for the farther information of such as are desirous of exemplarie instruction, I have set downe in order following the delineation of the proportion of such things as in my judgement seemed most necessarie for young beginners, and those in such easie demonstrations as for the most part they consist of equall squares, and require no more for their right understanding, then diligent observation, I might have filled a whole Booke of such like: but having considered that what I had done, was a sufficient ground for a farther procession, I thought fitting to leave each person to the exercise and practise of his best Invention.

Several Observations, in drawing a Head after the Life
And because the greatest difficulty, and principal parts of this Art consist in some part in drawing the lively Resemblance of a Face, therefore I thought it very necessary to add this as a further Direction to draw any Face after the life. Therefore if you will draw any Face after the life, that it may resemble the party you draw it after ; take notice in the First place of the Physiognomy or circumference of the Face, whiter it be round or long, Fat or Lean, Big or Little, […], then you must diligently and judiciously observe and discern all the Gentle Master Touches, which gives the Spirit and Life to a Face, and discovers the Grace or Disposition of the Mind, wherein lieth the whole Grace of the Work, and the Credit of the Artist, you may easily discern a smiling Countenance in the Corners of the Mouth, when they turn up a little ; […] ; there are also some touches about the Eyes and Mouth which you must diligently observe, which gives the Spirit and Life to a Face.
