2301 KIRCHER (Athanasius, S.J.) PIIONURGIA NOVA, sive Conjugium Mechanico-Physicum Artis 

 ct Natune Paranympha Phonosophia concinnatum, qua Universa Sonorum Natura, Proprietates, 

 Vires Effectunmqne Prodigiosorum Causse, nova et multiplici Experimentorum Exhibitione 

 enucleantur; Instrumentorum Acusticorum, Machinarumque ad Naturae prototyponadaptandarum, 

 etc. etc. etc. describitur; with fine portrait of the Emperor Leopold by G. A. Wolfgang, and 

 numerous copperplates in text, besides woodcuts and diagrams, folio, fine copy in old sheep (back 

 slightly damaged) ; RARE, 1. Is Campidonce, 1673 



The author was one of the foremost scientists of Germany during the XVII. Century, and although his works do not con- 

 tain many new discoveries, they are valuable for giving an encyclopedic view of the sciences treated as they were known 

 in his time. For the historian of physical science they are invaluable. 



He is known as the inventor of the magic lantern (originally suggested by Porta), and of the seolian harp (in the last- 

 named work), unless that honour belongs to St. Dunstan. He was also the first to mention physiological colours, and to 

 issue charts of the oceanic currents.

The author was one of the most biilliant and versatile of Irish men of science. ' He corresponded with all the sarants 

 of Europe; his Wednesday evenings were the resort of strangers of distinction ; the Empress Catherine sent him her por- 

 trait. His library despatched from Galway to London in 1780, was captured by an American privateer. An accomplished 

 linguist, a brilliant talker, and an adept in even Italian music, owing to a weakness of the throat he lived on ham and milk ; 

 kept a pet eagle, and refused a baronetcy from Lord Castlereagh." D. N. 1L

' Klaproth's researches in analytical chemistry were rightly looked upon at that time as patterns for the youngpr 

 generation of chemists. They aimed at establishing the composition of minerals by means of improved analytical 

 methods, and thereby laying the foundation fora chemical classification of them.' Prof. E. r. Meyer.
