not sufficiently widely known to be called " Australian Men of 

 Mark," and so the Chief-Justice decided against the enterprising 

 publishers. Furthermore, the Chief-Justice ruled that all con- 

 tracts entered into on account of the book, and not yet carried 

 out, were null and void. 



— Manganine is the name of a new alloy, consisting of copper, 

 nickel, and manganese, which has been brought on the market, 

 says the Engineering and Mining Journal, by the German firm, 

 Abler, Haas, & Angerstein, as a material of great resisting power. 

 The specific resistance of manganine is given as forty-two microhm 

 centimetres; that is, higher than that of nickeline, which has 

 hitherto passed as the best resisting metal. Another advantage of 

 manganine is its behavior under variations of heat, the resistance, 

 it is claimed, being affected only in a minute degree by high tem- 

 peratures. It is therefore adapted for the manufacture of measur- 

 ing instruments and electrical apparatus in general, which are 



required to vary their resistance as little as possible under diflferent 

 decrees of heat. A further interesting fact is that while other 

 metals increase their resistance by the raising of the temperature, 

 that of manganine is diminished. 



— M. de Quatrefages, the well-known anthropologist, died on 

 Tuesday, January 12. He was born, says Nature, in 1810, and 

 studied medicine at Strasburg. Afterwards he became professor 

 of zoology at Toulouse, where he had settled as a medical practi- 

 tioner. In 1855 he was made professor of anthropology and eth- 

 nology at the Jardin de Plantes, Paris. He had already been 

 admitted to the Academy of Sciences in 1852, and he was an hon- 

 orary member of many foreign Itarned societies. Numerous 

 friends and pupils were present at the funeral, and addresses were 

 delivered by M. Milne-Edwards, and other men of science. The 

 most famous of his writings are his " Crania Ethnica " and 

 " Etudes des Races Humaines." 



PROPRIETARY. 



ATonIc 



A most excellent and agree- 

 able tonic and appetizer. It 

 nourishes and invigorates the 

 tired brain and body, imparts re- 

 newed energy and vitality, and 

 enlivens the functions. 



Dr. Epheaim Bateman, Cedarville, N. J., 

 says: 



" I have used it for several years, not only 

 in my practice, but in my own individual 

 case, and consider it under all circumstances 

 one of the best nerve tonics that we possess. 

 For mental exhaustion or overwork it gives 

 renewed strength and vigor to the entire 

 system . ' '

FOSSIL RESINS. 



This book is the result of an attempt to 

 collect the scattered notices of fossil resins, 

 exclusive of those on amber. The work is of 

 interest also on account of descriptions given 

 of the insects found embedded in these long- 

 preserved exudations from early vegetation.
