 In applying the thcor\ lo lllcasuremcnl^ oi the 

 decrease of velocity of ra\s in pa>sinf:; through matter, 

 Bohr has deduced t lie relation 1 \ „ \') \'o'"^^', where 

 Vo = initial velocity, V = final \elo(it\-, / thickness, 

 c = constant. Existing measurements ha\ c all been j)ui 



in theform \V - V* =K/ (2). Ilus last ecjuation 



reduces to Bohr's form in the case where \' and Vq 

 are nearly equal. The value ot c lor aluminium 

 deduced from Terrill's observations is 4-0 x 10* *, while 

 that calculated from Bohr's theory is 4-1 xio**. —

 A. J. Turner: A revision of the Australian Aner- 

 astrianae (Lepidoptera). Only five Australian genera, 

 which can be easily tabulated, namely, Statina, 

 Calamotropa, Emmalocera, Anerastria, and Saluria, 

 are recognised. Four species are described as new.

 temperature organism of fermenting tan-bark. Pt. iii. 

 The organism produces carbon dioxide from a number 

 of carbon compounds. These include carbohydrates 

 such as saccharose, dextrose, levulose, maltose, 

 lactose, galactose, xylose, dextrin, starch, gum acacia ; 

 alcohols such as niannit, glycerin, amyl, and ethyl 

 alcohols ; salts of organic acids such as citric, lactic, 

 succinic, acetic ; nitrogenous substances such as 

 peptone, asparagin, meat-extract. Ammonium salts 

 and urea can serve as sources of nitrogen. Raffinose 

 antl mulin are scarcely fermented. Oxalates and 

 formates are not attacked. — T. Steel : On some
