The first work is the Thifd Edition of Regiomontanus's trigonometry, a second having been published in 154<;. 

 Appended is 'Tractatus super Propositiones Ptolemaei da Sinubus et Chordis ', by Gkorc Pkukrbach (Purbachius), the 

 reacher of Regioiiiontanns. 



"This is tlie earliest modern systematic ex-position of trigonometry, plane and spherical, though the only trigono- 

 tiietrical fum-tions introduced are those of sine and cosine'.— jr. W. R. Ball. 



' Regiomontanus and Purbach adojjted the Hindoo m/zc in place of the Greek choM of dimU'- tlie ai->: Regioniontanus 

 'inphasised the use of the ^( /(//«/(< in trigonometry, and following out some ideas of his master, calculated a table of 

 tangents . . . He was the author of a complete treatise on trigonometry, contAiniP;^ solutions of both plane and spherical 

 triangles. I'he form which he gave to trigonometry has been retained, in its main features, to the present day. . . . 

 Regiomontanus ranks among the greatest men that Germany has ever produced.'— P/o/. Cajori. 



Nothing is known of the author of the second work, who is not mentioned by 3Iontucla or Poggen<lorff(whoinistaVenly 

 attributes the work to Regiomontanus), or in other bibliographies. It forms an appendix to the tirst work, and - 

 especially interesting for its lumierous well-executed woodcuts, which include many on artillery bombarding fortresses. 

 which are still based on the contemporary notion that the projectile travels in a straight line, and after its strengtli is 

 si)ent, drops vertically (c. .Vo, S212 onte). 



Poggendorff mentions a Johannes Xoviomagus(Jan Bronckhorst), 1404-1570), who for some time professed mathematics 

 at Rostock ; but there is no evidence to connect him with the above Daniel Santbech Noviomagus.

This treatise on physics, which is still based on Descartes's theory of vortices, was very popular in its time, and 

 contains many interesting experiments.

The author's was the la.st of the classic .series of experiments made by Robert Hooke, G. B. Guglielmini in IT'.'l, and 

 Benzenberg in 1802 (r. So. 338«'>i(e)to ascertain the Easterly motion of a falling Ijody, caused by the rotation of the 

 earth. All the.se experiments ' showed, in addition tx> the predicted Easterly deviation, also a small .Southerly displace- 

 ment. For this no satisfactory explanation has yet been given ' {I'rof. Cojoil).

 translated and edited, with Notes and Appendix, by William Gregory, m.d., f.r.s. E., with 

 3 folding plates, and woodcuts, 8vo. cl., 6s 1850 



This is the work that contains the author's imaginary di.scovery of »<l, a physicjal force intermediate between 

 electricity, magnetism, heat, and light, to which the phenomena of hypnotism Cthen ' mesmerism ') are to be due. Id its 

 narrower sensi^ it agrees i)erhap3 best with Prof. Forel's nrnrokifinf.-'. 



Th« subject may still otter a field of si>eculation to the scientitte mystic in connexion with the undiscovered octaves of 

 ether waves. 



It consists of :.' parts, the first treating of ' Physico-Physiological Researches on the Ijnponderables, in their Relation 

 to the Vital Force , and the second of ' Magnetic or Odylic Light.' 



The author is generally known as the discoverer of creosote and parattin.
