for procuring antique and rare medals, with directions to distinguish the true 

 from counterfeits, presenting a catalogue of some alphabetically ; and in this 

 place he shows the several tricks used in making the cheats and false ones, and 

 sets down some ways to take off medals by a sort of glue, and the like. In the 

 seventh chapter our author discourses of mints, and the most skilful artists, 

 with directions to collect and dispose medals for the cabinet, and gives his opi- 

 nion and reasons against either debasing the coin, or enhancing the value. The 

 eighth chapter gives an account of heads and effigies in taille douce, with par- 

 ticular directions for such a collection. 



The ninth chapter, which concludes the work, contains a digression con- 

 cerning physiognomy, giving his opinions and conjectures of the natural dis- 

 positions, wit, and qualifications to be gathered from the observation of each 

 part and member particularly.

The design of this piece is to instruct the youth of Copenhagen in the rudi- 

 ments of natural philosophy, therefore the author delivers his elements in a 

 compendious method ; in which he treats of hypotheses, of the understanding 

 in general, then proceeds to principles, as matter, form, motion, extension, 

 divisibility, space, time, &c. Afterwards he handles particular qualities, as 

 heat, cold, fluidity, solidity, rarity, density, light, colours, sound, taste, smell, 

 gravity, magnetism, &c. He examines the several elements and systems of the 

 world, the earth with all its strata, inequalities, and fossils ; the air and heavens 

 with the meteors and celestial bodies. After which he descends to the functions 

 of animal, and vegetable bodies, as sensation in general, and all the senses in 

 particular : digestion, nutrition, secretion, excretion, respiration, generation, 

 muscular motion, vegetation, &c. 



Among the many opinions concerning the origin of springs, our author only 

 examines 3 or 4, and then he delivers his own opinion, which makes rain- 

 water, stopped by the strata of the earth, to be sufficient for the feeding of foun- 

 tains ; and this m.iy be calculated from the observations of M. Perault, and 

 Mariotte, to which Mr. Ray adds many illustrations in his Three Physico- 

 Theological Discourses, 2d edit. 1693.
