CtEOLOGY. 



Captain F. W. Hutton, F.G.S.. discusses the age of the 

 Orakei Bay Beds, which he refers to the Pareora system p. 307. 

 The same author describes 79 new species of Tertiary shells, 

 p. 313. Professor Julius von Haast, C.M.G., &c., criticizes the views 

 of the Geological Survey of N.Z. with respect to the age and 

 arrangement of the rocks forming the Southern Alps in Canterbury 

 and Westland, p. 332 ; and is answered (p. 337) by Dr. Hector, 

 Director of the Survey, who, in the course of his argument, states 

 that the Mount Potts and the Clent Hills beds form almost the 

 lowest and the highest members of a great Permio-jurassic system, 

 the sequence of which has been very clearly worked out in other 

 parts of New Zealand. The Permian base of this system has 

 never been found resting with any approach to conformity on the 

 Maitai series, which is Lower Carboniferous, the Upper Car- 

 boniferous or the Lower Coal measures of N.S.W. being still 

 undiscovered in N.Z. 



The Red Sunsets have been discussed in two papers by John 

 Meeson, B.A., p. 3.57 ; and William Ringwood, p. 386, who both, 

 after a careful summing up of such evidence as is obtainable, agree 

 that the approximate cause was the presence of Volcanic dust in 

 very high regions of the atmosphere, and that this was mainly, 

 if nob altogether, derived from the eruption of Krakatoa. 



The New Zealand Journal of Science, which has just died of 

 inanition to the regret of a loyal but insufficient proportion of 

 paying subscribers, closes with a somewhat bitter but humourous 

 farewell to its supporters under the heading " Moriturus te 

 Salutat " in explanation of the causes which led to the premature 

 decease of this promising journal, at the age of two volumes, or 

 four years.
