Marine shells are found in the lower beds, while from about the middle 

 of the beds I obtained broken moa bones and fragments of moa egg-shell. 

 I have little doubt but that these gravels are the same as those in which the 

 bones are found at Motanau. In the latter locality the presence of the lignite 

 bed may indicate an unconformity between the higher and lower parts of the 

 gravel deposit. This may be so and yet the younger upper beds may be of 

 greater age than the alluvial deposits of the Omihi Valley. The Motanau 

 moa-bone beds would therefore belong to the older beds in Glenmark Creek 

 already referred to. These Glenmark beds belong either to the gravels of 

 the plain south of the Waipara, or to the Upper Miocene beds forming 

 gravels extending south from the Weka Pass to Mount Grey Downs, and 

 forming part of the hills between Brown's Bridge and the mouth of the 

 Waipara Eiver. I should say they belong to the younger beds, and as in 

 character they agree with the gravels of Gore Bay, Cheviot Hills, we might 

 thus find a reason for correlating them with the Motanau moa-bone beds. 



Abt. LXXI. — Further Notes on the Thermal Springs in the Hanmer Plains, 



Provincial District of Nelson. By Julius von Haast, Ph.D., F.E.S. 



[Read before the Philosophical Institute of Canterbury, ith August, 1881.] 



In a paper read before the Nelson Association for the Promotion of Science 

 and Industry, on the 4th May, 1870, and printed in the " Transactions of 

 the New Zealand Institute,"* I gave the results of a short visit to these 

 springs on 20th February of the same year. Since then, during a stay of a 

 few weeks at the same locality, from the end of December, 1876, to middle 

 of January, 1877, I had ample opportunity to verify not only the observa- 

 tions previously made, but to add considerably to the stock of our scanty 

 information as to the temperature of these remarkable springs, by a series 

 of carefully conducted observations during a number of days, and I now take 

 the liberty to lay the results thus obtained before you. 



The barometric readings were obtained with an aneroid of Negretti and 

 Zambra, and those of the thermometer taken from a set of maximum and 

 minimum thermometers of the same firm, the instruments before starting 

 having been com^jared with the standard instruments of the meteorological
