Formation and General Features of Ruwenzori. 



By far the most interesting altimetric observations are 

 those which were taken by Lieutenant T. T. Behrens in 1903 

 durino- the Anfflo-German frontier delimitation. He then fixed 

 trigonometrically the height of the two peaks which appeared 

 to be the highest, as well as of four other points. It was, 

 however, only after the publication of the Italian map that he 

 was able to identify with certainty the position of these peaks, 

 and hence to obtain all the data for an exact calculation of 

 the altitudes on the basis of the angles taken. It is worth 

 while to compare his results with those of H.R.H. 



This is not the place to discuss the relative value of the 

 two series of numbers. In Appendix B, Prof Omodei gives 

 in extenso all the data of H.R.H.'s observations, and a critical 

 exposé of the methods adopted, and of the precautions taken 

 in calculating the altitudes. 



Dr. A. Roccati has written a detailed account of the geology 

 and mineralogy of Buwenzori, which is published in the volume
