72 Analysis of LMvafrom Vesuvius. 



From two different eminences he saw the hill from which 

 the mysterious Niger (there called Tembie) springs — the hill 

 is named Loma, and forms the commencement of a chain ex- 

 tending to the northward from the Kissi country, where they 

 first arise. The Niger flowing from the hill of Loma in 9 deg. 

 15 min. N. lat. and 9 deg. 36 min. W. long, marks the boun- 

 dary between Sangara and Soolimana, the former being to the 

 right or east, and the latter to the left or west. The geogra- 

 phical site of Loma was ascertained by taking the bearings 

 from two points thirty miles distant from one another ; and 

 from the talent and well-known accm-acy of Captain Laing, 

 there can be no doubt of the observations being correct. 



The Camaranca River was also visited at several parts of 

 its course by Captain Laing : it rises two days' journey east of 

 the Niger, and makes a bold attempt to unite with the Ro- 

 kelle, about ninety miles distant from this colony, approach- 

 ing at one place within a few miles of it. In its westerly 

 course it runs through the centre of the Kooranko countr}', 

 which is one of the largest that we have any knowledge of on 

 this side of Africa. 



Captain Laing also makes mention of the Mungo *, alarge and 

 very fine river, which disembogues itself into the ocean through 

 the same mouth as the Scarcies ; it is a river of greater mag- 

 nitude than the latter, and it has hitherto been unknown to 

 Europeans ; rises twenty miles to the northward of RokeUe, 

 close to Beilia, a Foulah town two days' journey S. E. from 

 Timbo. It was at this town that Serjeant Tuft and Musah 

 Kanta were left by Alimamee Abdolkader, when he went to 

 attack Sangara. Tl'he king crossed the Niger the second day 

 fi-om Beilia. 



In the Limba country the Mungo is joined by the Kabba, 

 a river upwards of one hundred yards broad, and which rises 

 about twenty miles south of Timbo, the capital of the Foulahs. 

 Captain Laing places Timbo in 1 deg. 52 min. north lat. and 

 10 deg. 34 min. west long. 



It is to be earnestly hoped that this Mission, executed with 

 so much skill, prudence, and success, will pave the way for 

 another enterprise, which Captain Laing is anxious to under- 

 take from the vei-y source of the Niger to its mysterious termi- 

 nation. 



ANALYSIS OF LAVA FROM VESUVIUS, 



Several chemists have analysed the lava of the last eruption 



* It is the wish of Captain Laing to change the native name of this river 

 to M'Carthy's River, in honour of oui' esteemed Governor Sir Charles 

 M'Carthy.
