WE learn from Science that the Italian Societa Positivista has 
established a bi-monthly journal, // Pensiero Moderna, published at 
Via Collegio Romano 26 (Rome?), and edited by Prof. Sergi. The 
object of the society is to demonstrate the importance of science for 
modern life. 
The Americon X-ray Journal is edited and published by Dr Heber 
Roberts, St Louis, Mo., and is intended for the medical profession. 
We may mention here the Bulletin of the Geological and Natural 
History Survey of the Chicago Academy of Sciences. The first is a 
monograph of the lichens of Chicago and the neighbourhood by 
W. W. Calkins.
