In the Firfl the Author handleth 
The Conftrudion of the Tables of Sines % Tangent s^tA Secants. 
The Refolution of Right-lined Triangles. 
The Menfuration of the diftance of Obj'eds, as well unacceflible asac- 
•ceffible. 
I The Heights of Mountain$,Towers, Clouds, Rainbowes . the Depths of 
Wells and Vallies. He concludes the perpendicular height of the burning 
Mountain tALtna to exceed 5 Bowman-Miles ; of Mount Caucafm beyond 
the Cafpian-Se^ to be 51. Mount Athos of 'Greece 28. Cafius of Syria 20. 
the 'Alps of Italy and Pic of Tenarife 10 Miles, The Circumference of

In ihefecond Book, he handles theDimenfion of Plain Surfaces, either 
Regular or Irregular, and takes the Iconography or Defcription in Paper, of 
any Figure given of the furfaceof the Earth : Aflerts the Poflibihfy of the 
Quadrature of the Circle • and handles the Transformation of Plain Fi- 
gures, to wit, their Addition, Subftradhon, Augmentation, Diminution^ 
Comparifon ; further the dividing ef a plain Triangle, in a given Reafon 
by a line paffing through a point any where affigned : This he doth largely 
in 16 Propofitions, becaufeupon it chiefly depends the Divifion of other 
Right-lined Figures . and becaufe he found divers Determinations want- 
ing, when the point is given within. Thofe that are defirousto fee this 
Analytically done, may find it in Herigon with a Conftrudion thereof; as 
alfo a Geometrick Conftrud ion thereof in VanSchootens Mifcellanea ; and 
another rnoft excellent ConftrucTion at the end of Van Ceulen de Circulo & 
Adfcriptis. 
Afterwards our Author proceeds to the dividing of other Figures, in n 
given Reafon, or by parallel lines,and ftieweth how to apply the whole to 
Pratlice in the Field. 
In the third Book the Author firiHneafoedi fuch Solids as are contained
