New Serials 



We learn from Science that the Italian Societa Positivista has 

 established a bi-monthly journal, // Pensiero Moclerna, published at 

 Via Collegio Romano 26 (Home ?), and edited by Prof. Sergi. The 

 object of the society is to demonstrate the importance of science for 

 modern life. 



The American 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.
