228 VETERINARY TOXICOLOGY 



Post-Mortem Appearances. — These are not well marked. 

 The mucous membrane of the rumen may be easily detach- 

 able, but there is not extensive inflammation. Rhododen- 

 dron leaves will probably be found in the stomachs. 



Treatment. — Most of the cases referred to recovered 

 under treatment by means of a brisk oleaginous purgative, 

 followed by chlorodyne or counter-irritants to abdominal 

 pain, and general stimulants and tonics, such as ammonium 

 carbonate and spirits of nitrous ether. 



Wallis Hoare ^ in the case of a young cow, gave brandy ; 

 chlorodyne, Bii- ; sp. seth. nit., §iv. ; ol. lini, O.iii. ; and 

 ' opiates, with recovery on the fifth day. 



Chemical Diagnosis. — The history of the case and the 

 detection of leaves of the plant in vomit or contents should 

 render this superfluous. As, moreover, the chemical reac- 

 tions of the active principles haVe not yet received precise 

 study, a diagnosis by this means is at present of doubtful 

 value. 



In a case of a cow poisoned just after calving, Wallis 

 Hoare had difficulty in differentiating from milk fever, until 

 he observed the vomition of rhododendron leaves.

Cases of poisoning by Azalea are not numerous, but the 

 California azalea {A. occidentalis) is dreaded by shepherds 

 in the Southern Sierras. According to Cornevin, the 

 symptoms approach those of Lolium temulentum (q.v.), whilst 

 the same authority quotes Xenophon's narrative of the 

 symptoms of delirium and prostration exhibited by those of 

 his soldiers who partook of honey from azalea in Asia Minor.
