" "And since in vegetables, their growth and the preservation of their vegetable life is promoted and maintained, as in animals, by the very plentiful and regular motion of their fluids, which are the vehicles ordained by nature, to carry proper nutriment to every part; it is therefore reasonable to hope, that in them also, by the same method of inquiry, considerable discoveries may in time be made, there being, in many respects, a great analogy between plants and animals.

November the sixth following, viz. in the Year 1741 Martin Triewald, Captain of Mechanicks and Military Architect to the King of Sweden, and Fellow of the Royal Society at London, in a Letter to M.D. and Secretary of the Royal Society, says, that "this Spring he had invented a Machine, for the Use of his Majesty's Men of War, which went to block up Petersburgh, in order to draw out the bad Air from under their Decks, the least of which does exhaust 36172 cubick Feet of Air in an Hour,"...
We have from the foregoing Experiments many proofs of the very great and different quantities of moisture imbibed and perspired by different kinds of Trees, and also of the influence of the several states of the air, as to warm or cold, wet or dry, have on that perspiration. We see also what stores of moisture nature has provided in the Earth against a dry season, to answer this great expence of it in the production and support of vegetables; how far the dew can contribute to this supply, and how insufficient its small quantity is towards making good the great demands of perspiration: And that plants can plentifully imbibe moisture thro' their stems and leaves as well as perspire it.

About the Year 1675, William Walcot, Brother to Sir , obtained a Patent for making Sea-Water fresh: And the King, before the Grant of this Patent, had the curiosity to go and see Mr. Walcot do it, which was by distilling it in a very large Still; into the Still he put some Ingredient, which was to cure the distilled Water of any noxious Quality: But what it was, he kept a great secret. I suspect that the principal thing was only Distillation, because in all his printed Accounts of it, he purposely avoids the calling it a Still, but calls it a Machine or Engine, and Distilling he calls the working of the Machine, not Distilling.
