Memoirs of the Life of Lewis Brugnatelli. 325 
Brera, 1797, one volume. Giornale di Fisica, Chimica e Storia 
Naturale, 1808-18; the first eight volumes were edited by Brug- 
natelli alone, the remainder in company with Brunacci, Con- 
figliachi, and his son. 
His detached memoirs and papers must be enumerated in their 
chronological order. In 1784 appeared his ¢ Letter on the means 
of preserving various insects, and chemical analysis of the gastric 
juice,’ in the Oposculi scelti of Milan, vol. 7. In 1785, ‘ Letter on 
the solvent power of the gastric juice of certain animals,’ 2). vol. 8; 
and ‘ Ou the peculiar properties of vitriol of iron,’ published in 
Crell’s Annals. In 1786, ‘ Memoir on the nature of cork,’ Opus. 
scelt. Milan, vol. 9. In1787, On the action of turnsole upon 
animal matter ‘On the sediment of urine, On the corruption of ani- 
mal matter in different kinds of acid, and Experiments on the con- 
stituent parts of alcohol, of gall,’ &c. all published in Crell’s 4n- 
nals. In 1788, ‘ Fructification of the rose, and analysis of the 
saliva,’ Rozier’s Journal, vol. 33 ; ‘ New sympathetic inks, me- 
thod of restoring ancient writings, and discoveries respecting ve- 
getable substances,’ Biblioteca, vols. 3 and 4. In1789, * New me- 
thod of obtaining acid from concentrated vinegar,’ 7d. vol. 10. In 
1790, ‘ Method of rendering paper and ink indestructible by fire, 
new mode of bleaching wax,’ ib, vols. 14 and 17. ¢ Singular pro- 
perty of certain substances to move themselves upon water,’ Ann. 
vols. | and 22; ‘On oxygenated muriatic acid used as a photo- 
meter, and easy mode of discovering nitrous in vitriolic acid,’ il. 
In 1791-2 and -3 appeared ©A new mode of preserving and con- 
centrating citric acid, a new neutral salt, observations on some in- 
sects, and chemical reagents for the use of travelling naturalists,’ 
ib. vol. 4. In 1794, ¢ Easy mode of impregnating water with the 
acidulous carbonat of potash, on the perennial heat of the tepid 
water of St. Pellegrino, and chemical analysis of the vegeto- 
mineral mire of Trescore,’ zl. vols. 5 and 6. In 1795, ‘ Letter on 
animal electricity, on caloric and light, medical observations, 
and proposals for reforming the new nomenclature,’ il. vols. 7 
8, 9, 10, and 13. This latter work excited considerable atten- 
tion to the chemical and literary labours of the Pavian Professor: 
the nomenclature which he proposed has been generally adopted 
by Italian chemists, and it is perhaps well suited to the genius of 
the language. Although subsequent discoveries have not sanc- 
tioned the principles which it favours, it has nevertheless been 
extremely useful in Italy, in a country where numbers read and 
speak of chemistry and chemical subjects without any practical 
knowledge; where there are very few practical, but many theo- 
retical and critical chemists, who, being amused with literary 
subtleties and refinement of terms, have disseminated a taste for 
chemical studies which may ultimately lead to practical expe-
