Systematische Darstellung aller Erfahrungen in der Naturlehre entworfen. 



Vol. I and n : Systematische Darstellung aller' Erfahrungen liber allge- 

 meine verbreitete Potenzen von Ludwig von Schmidt, genannt 

 Phiseldeck. 2 vols. 



Vol. Ill : Systematische Darstellung aller Erfahrungen iiber die einzelnen 

 Metalle in zwei Biinden, von Karl Albrecht Kielmann. Aarau, 

 1807. 3 vols., 4to. Vol. I : pp. xxxii-543 and eleven plates. 11: 

 pp. iv-420 and plates 12-17. iii : pp. xxxiv-498 and one plate. 



This is an ambitious attempt to present a summary of all facts based on 

 experiments with the known elementary bodies. Vol. II treats of light, 

 heat, electricity, galvanism, magnetism, oxygen, hydrogen, water, 

 nitrogen, carbon and atmospheric air ; vol. Iil, of the metals and their 

 known combinations with the preceding and with each other. The 

 whole is very systematically arranged, and certainly gives an excellent 

 view of chemical knowledge at the time. The work abounds in cita- 

 tions and bibliographical data. Historical notes accompany each 

 metal.
