94 ACACIA SENEGAL 



licaiion to burns and scalds, and to sore nipples, &c. The 

 io'cal* Application of powdered gum has likewise been found useful 

 in citetking haemorrhage from leech-bites ; and when blown up 

 the nostril it has arrested severe epistaxis. 



Gum also appears to possess some nutritive properties, as it 

 forms almost exclusively the food of those engaged during the 

 period of its collection, &c. ; and also in times of scarcity of the 

 Hottentots. 



Gum is also largely used for other purposes than in medicine. 

 Thus large quantities are employed in the arts for giving lustre 

 to crape and silk ; for thickening colours and mordants in calico 

 printing, &c. ; for suspending the tannate of iron in the manu- 

 facture of ink and blacking ; and for other purposes. The bark 

 and unripe fruits of several species of Acacia are also used for 

 tanning and dyeing.
