Monsieur _Hugens_, inquiring also in a Letter, newly written by him to a Friend of his in _England_, of the success of the attempts made by an ingenious _English_ Man for perfecting such Glasses, and urging the prosecution of the same, {99} so as to shew by the effects the practicableness of the Invention, mentions thereupon, That he intends very shortly to try something in that kind, of the success whereof he declares to have good hopes. Monsieur _du Son_, that excellent Mechanician, doth also at this very present employ himself in _London_, to bring _Telescopes_ to perfection, by grinding Glasses of a _Parabolical_ Figure, by the means whereof he hopes to enable the Curious to discover more by a Tube of one Foot long, or thereabouts, furnished with Glasses thus figured, then can be done by any other Tubes of very many times more that length: The success hereof will ('tis thought) shortly appear. * * * * * _An Advertisement of a way of making more lively Counterfeits of Nature in _Wax_, then are extant in _Painting_: And of a new kind of _Maps_ in a low _Relievo_. Both practised in_ France. This was communicated by the Ingenious Mr. _John Evelyn_, to whom it was sent from _Paris_ is a Letter, as followeth. Here is in our Neighbourhood a _French-man_, who makes more lively Counterfeits of Nature in _Wax_, then ever I yet saw in _Painting_, haveing an extraordinary address in modelling the Figures, and mixing the Colours and Shadows; making the Eyes so lively, that they kill all things of this Art I ever beheld; He pretends to make a visit into _England_ with some of his Peices. I have also seen a new kind of _Maps_ in low _Relievo_, or Sculpture; For example the Isle of _Antibe_, upon a square of about eight Foot, made of Boards, with a Frame like a Picture: There is represented the Sea, with Ships and other Vessels Artificially made, with their _Canons_ and Tackle of Wood fixed upon the surface, after a new and most admirable manner. The Rocks about the Island exactly form'd, {100} as they are upon the Natural Place; and the Island it self, with all its Inequalities, and Hills and Dales; the Town, the Forts, the little Houses, Platform, and Canons mounted; and even the Gardens and Platforms of Trees, with their green leaves standing upright, at if they were growing in their Natural Colours: in _fine_, Men, Beasts, and whatever you may imagine to have any protuberancy above the level of the Sea. This new, delightful, and most instructive form of _Map_, or _Wooden Country_, you are to look upon either _Horizontally_, or _side-long_, and it affords equally a very pleasant object. * * * * * _Some _Anatomical_ Observations of Milk found in Veins, instead of Blood; and of Grass, found in the Wind-pipes of some _Animals_._
