5. "Additional Information concerning the Eruption at 

 Eotomahana," by Dr. Hector. Illustrated by photographic 

 views taken by Mr. C. Spencer. 



Dr. Hector stated that the curves registered by the barographs or self- 

 registering barometers at Auckland, Eotorua, Wellington, Lincoln (Christ- 

 church), and Dunedin, had been received, and showed curious modifications, 

 which might throw some light on these eruptions. The Lincoln barometer 

 showed on the 21st May, at 8 p.m., a very marked indentation, that reap- 

 peared on many days at intervals of twenty-four hours. A similar, but 

 inverted, notch was noticed on the 24th at Eotorua, and for some days 

 subsequently, but was wanting at other places. A still more curious fact 

 was, that further notches had appeared on the 28th June and the 1st July, 

 (after the eruption,) at Lincoln, which made him doubt any possible connec- 

 tion between these curves of the barograph and our New Zealand eruptions. 

 He pointed out that at the time of the Sunda eruptions, in 1883, such dis- 

 turbances in the atmospheric pressure were noticed here and at other places, 

 and suggested that possibly the recent eruptions of Etna, or some outbreak 

 of Mounts Erebus or Terror, in the Antarctic Continent, might have some- 

 thing to do with the matter. 



Exhibits. — Dr. Hector showed a new and valuable food fish, caught off 

 the Island of Kapiti by Mr. S. H. Drew. It belongs to the genus Pimelep- 

 terus, all recorded species of which are confined to tropical seas ; but Dr. 

 Giinther states in a private note that a fish of this kind caught in Sydney 

 Harbour has been erroneously placed in the genus Pachymetopon. The 

 name proposed for this new species is Pimeleptenis dreirii. 



A specimen of Girella simplex, caught in the Wanganui River, also by 

 Mr. Drew, was exhibited. This fish, Captain Gilbert Mair recognises as 

 the true Parore of the Natives, which at certain seasons frequents the man- 

 grove swamps in the North, and about the true nature of which there has 

 been much uncertainty.

 Phenomena of Earthquakes and Volcanoes," by W. T. L. Travers, 

 F.L.S. {Transactions 1^.321.) 



Mr. Crawford doubted if volcanoes were chiefly situated in tropical 

 regions. He had been surprised to hear of late that the supposed craters in 

 the moon were really made of ice. This would need explanation. 



Mr. Hudson made some remarks regarding the fluid condition of the 

 earth's interior not being compatible with the observed effects of the moon's 

 attraction,
