12. Mines in Australia, (Adelaide Observer; Athenaeum.) — The 

 exports of lead and copper ores from South Australia for the past year 

 (1847), have been declared in a semi-official Report at more than 

 180,000 pounds. The silver-lead mines of Glen Osmond are being 

 vigorously and successfully prosecuted, and to the productiveness of 

 the contiguous property of Wheal Watkins is about to be added a like 

 productiveness of Wheal Gawler, also adjoining. 



13. The Nile, (Athenaeum.) — Dr. Bialloblotzky is about to undertake 

 an exploring tour into the interior of Africa. His main object is to make 

 one more attempt to settle the disputed geographical question of the 

 position of the sources of the Nile. He was to leave Suez for Aden 

 about the 23d of October, the East India Company having granted him 

 a free passage in one of their steamers. The plan is to proceed from 

 Aden to Mombas on the East Coast of Africa, in about 4° of South lati- 

 tude, and there, or in its vicinity, make arrangements for travelling 

 into the interior with a native caravan or otherwise. It is anticipated 

 that a journey of 300 or 400 miles from the coast, in a direction be- 

 tween W. and N.W., will bring the traveller to the edge of the table 

 land of Eastern Africa, at the water-parting between the basin of the 

 Upper Nile and that of the rivers Lufidgi, Ozi (Pokomozi or Maro) and 

 Sabaki, flowing eastward, into the Indian Ocean. 



14. A Cabinet of Minerals for sale, collected by the late Dr. Crawe, 

 of Watertown, Jefferson Co., N. Y. — The cabinet of minerals of the 

 late Dr. Crawe, consists of rare and choice specimens, obtained in part 

 by personal efforts, in part by exchange with gentlemen at home and 

 abroad. It is particularly rich in the northern minerals of New York 

 and Nova Scotia, and contains 1,000 specimens or more. It will be 

 disposed of for a sum much less than its intrinsic value, and may be 

 regarded as an object of moment to public institutions or individuals 

 interested in this branch of science. Enquiries on the subject may 

 be made of Dr. Emmons, of Albany, or Doct. Gray, of Harvard Col- 

 lege, Cambridge. 



[Although I have not seen the cabinet of the late Dr. Crawe, I have re- 

 ceived from him so many and such excellent specimens, that 1 am well 

 convinced his entire collection must be very valuable, especially in the 

 local minerals of the region which he so faithfully explored. 



His specimens of crystallized mica — of crystallized apatite or phos- 

 phate of lime, and of fluor spar, have no superiors in this country, nor 

 the two former any equals as far as I know in any country. 



Dr. Crawe's zeal for science cost him his life, and his widow and 

 children have strong claims upon its cultivators and upon their country.

Obituary. 



15. William Oakes, A.M., well known as the most distinguished 

 botanist of New England, fell overboard from the ferry boat between 

 Boston and East Boston, and was drowned, on the 31st of July, 1848, at 

 the age of forty-nine years. The services which Mr. Oakes has ren- 

 dered to that department of natural science to which he was so enthu- 

 siastically devoted, his active fcindness of heart and liberal spirit, which
