able for economic treatment, its high per centage of iron, and its freedom from 

 all obnoxious constituents will render it of great value for iron and steel 

 manufacture. 



Yours &c., 



GEORGE FOORD, 

 Chemist and Assayer. 

 C. Gould, Esq., 

 Government Geologist for Tasmania. 



Mr. Gould commented on the disposition of the iron ore in the course of 

 two parallel lines, and remarked on the variations in its character accord- 

 ing to the formation traversed. He also pointed out the identity of the 

 Blue Hill Tier rocks with those largely developed at the great bend of the 

 Gordon and in other parts of Western Tasmania, and the possibility of 

 favorable conditions determining the existence of valuable minerals — this 

 inference being supported by the known presence of copper and lead ores 

 at Penguin Creek. He concluded by making a few remarks on the fossil 

 species of Unio occurring on the banks of the Tamar. 



In reference to the Trout ova taken from fish in the colony, ISIr. M. 

 Allport reported that in many the embryo fish were now visible under 

 the microscope. 



This was the more satisfactory as it would be conclusive evidence to all 

 those to whom the ova had been forwarded that successful impregnation 

 had taken place. 



Mr. Abbott brought under the notice of the meeting a series of 

 resultants derived from the 25 years' meteorological tables. He gave an 

 extract from a table by Professor Dove, and compared the temperature of 

 the various places therein enumerated with that of Hobart Town for the 

 different seasons of the year, showing in a very striking manner the 

 favorable character of the Tasinanian climate. He also read the following 

 extract from a paper read by Mr. Glaisher before the British Meteorolo- 

 gical Society : — 



" The greatest mortality (from all causes) was coincident with a temperature 

 of 30- to 35-, and the smallest .50- to 60'. The temperature of 65* to 70" being 

 much more fatal than 55* to 60*." 



It will be seen by the foUowdng that the temperature for Hobart Town 

 coincides with that given by ]\Ir. Glaisher as most favourable to health. 



Hobart Town. Mean 54*45 

 Spring =53 -99 -Summer —61 '95 

 Autumn = 54 -35— Winter— 46 *85 



In conclusion Mr. Abbott drew the attention of the meeting to the very 

 great amount of time and trouble required for copying and computing the 

 abstract sheets of the 25 Years' Tables, for which he considered a special 

 vote of thanks was due to ISIr. Roblia, the Curator of the museum, and 

 begged to move accordingly. 



Mr. M. Allport had great pleasure in seconding, as he could testify to 

 the very large amount of labour bestowed by Mr. Roblin upon the returns 

 in question, and also to his readiness at all times to use his best endeavours 

 in the interest of the society. 



The motion was agreed to. 



Discussion ensued in which Dr. Butler, Mr. Allport, Mr. Gould, Dr.' 

 Hall, Mr. Abbott and others took part, after which the usual vote of thanks 

 to the authors of papers, and the donors of presentations having been 

 passed, the meeting broke up.
