Discussion. 



The President said that the Society sincerely welcomed papers 

 of this nature, dealing with the general geology of some of the broad 

 ' borderlands ' of the Empire, of the structure of which so little 

 was as yet known. Especially was it interesting to note how large 

 a proportion of the results appeared to be due to the Author's own 

 travels and observations. 



• Mr. C. J. Aleord said that he had nothing to add to the paper 

 but corroboration. The expedition which he had conducted in the 

 Zambesi Valley was undertaken on behalf of the British South Africa 

 Company about ten years ago, and was attended with disastrous 

 experiences. All the oxen and horses were killed by the tsetse fly, 

 and the men died of malarial fever : he and one other (Lieut. Carden) 

 only reaching Salisbury, after walking back nearly 400 miles, with 

 nothing left but their lives. Most of the specimens of rocks and 

 other things which had been collected were lost. 



The Author thanked the President for his appreciative remarks, 

 and the Fellows present for their kind reception of the first paper 

 that he had brought before the Society.
