TABLE XXVIIL— ANALYSES OF TWO SAMPLES OF DJEBEL 

 GOURNIA PHOSPHATE IN THE NATURAL CONDITION. 



XI. Asia. — Phosphate of hme deposits have also been dis- 

 covered in Egypt, but their percentage of phosphate of Hme does 

 not exceed 50 per cent.^ It has also been found in Palestine, to the 

 west of the Jordan, near to the route followed by the caravans going 

 from Damascus in Arabia, and testing 80 per cent of phosphate of 

 lime, with 1 per cent of iron and alumina, and testing 10 per cent 

 of calcium fluoride. These deposits are not yet exploited com- 

 mercially. 



XII. Phosphates of Oceania. — There is found in certain isles 

 and on the coast of the Pacific Ocean considerable deposits of phos- 

 phatic material. Like Peruvian guano, which will be dealt with in 

 the sequel, they are of animal origin, but they differ essentially from 

 Peruvian guano by the almost complete absence of nitrogen, which 

 they have lost either by decomposition or under the influence of
