160 Royal Irish Academy. 



In tliis Memoir he gave a statement of the Middle Tertiary Climate 

 of the Arctic Eegions, from which he showed that at the latitude of 

 80° N". the climate must have been : — 



July Temperature 7 64°. 1 F. 

 Mean Annual 7 47°.0 F. ; 



the present climate being — 



July Temperature = 34°.0 F. 

 Mean Annual = 4°. 5 F. 



In order to convert the present climate of Lat. 80° N. into its Middle 

 Tertiary Climate, we, therefore, require an addition of 30°. 1 F. to the 

 July Temperature, and an addition of 22°. 5 F, to the Mean Annual 

 Temperature. 



Dr. Haughton then explained his method of calculating, numerically, 

 the change of temperature in the Arctic Eegions, north of 70° Lat., 

 which the Gulf Stream, the Kuro Scivo, and the Northern Mosambique 

 were capable of producing ; and showed that they fell short of what was 

 required by the testimony of the Tertiary Flora ; and required the aid 

 of sources of heat not furnished by TJniformitarian Theories. 



Dr. Haughton having resumed the Chair, Mr. Barrington, by per- 

 mission of the Academy, read his Paper " On the Flora of the Blasket 

 Islands." 



The Chairman announced that Francis Davis "Ward, j.p., and Henry 

 "Wm. Mackintosh, ir.A., were duly elected as Members of the Academy. 



The Secretary laid on the table a Eeport by H. C. Hart, b.a., on 

 the Botany of the Galtee Mountains. 



Dr. Macalister exhibited the impression of an Aborigiual Hand 

 from a cave in New South Wales, presented to the Museum of Trinity 

 College by Dr. S. Knaggs, of Newcastle, N. S. W. ; and a Necklace of 

 Human Teeth from the Soloman Islands, presented by Dr. Goode, R.N. 



The Secretary announced the list of Donations, and the thanks of 

 the Academy were accorded to the respective Donors. 



The Treasurer reported that the Council had recommended the 

 Academy to grant the sum of £20 to Messrs. Balkwill and Joseph 

 "Wright for the examination of the Foraminifera of Dublin Bay, and 

 £30 to Mr. Gerrard Kinahan, in aid of his Researches on the Chemical 

 Impurities of River "Waters, and proposed that the grants be con- 

 finned, which motion was carried. 



The Academy adjourned.
