cases. It has been remarked, that horses that have been hard- 

 worked, and then turned out into pasture, are the most apt to 

 suffer in this manner ; whereas the occurrence scarcely ever 

 takes place among breeding stock. The remedies usually em- 

 ployed are saline purgatives to carry off the noxious matter ; 

 and alkaline and earthy solutions to absorb the carbonic acid, 

 as soon as it is generated. 



As a timber, the wood is very hard. It is not, however, 

 adapted to saw into planks or boards, from the stem being 

 very much twisted and crooked. It is sometimes split into 

 shingles, which are very durable; but the holes for the nails 

 require to be bored. The principal use of the wood is for 

 fuel, being the best adapted for that purpose of any that is 

 made use of; and, from its being of rapid growth, a constant 

 supply can be obtained. 



Browne has erroneously called this the Poponax, and in this 

 he has been followed by Lunan.
