0LEANDER POISON
 A FEW EXPERIMENTS
Prof. Wilson of the Experiment Farm Is Thoroughly Demonstrating It's Effect on Live Stock.

A great deal has been printed in The Republican from time to time concerning the oleander poisoning of stock but heretofore all has been in a sense speculative. The information has come mainly from veterinarians whose opinions were. formed after post mortem examinations of dead animals in the stomachs Of which oleander leaves had been found. Death was at tributed to oleander poisoning because of the similarity of symptoms in all cases where the leaves were found. Nevertheless. under what conditions and in what quantities. were all guess work and il was hard to sav positively that the oleander poison caused death. even though the veterinarian believed it to be so.
 Lack of information on this subject and the fact that the oleander is grown here in such proiusion as an ornamental plant. led Professor Will son who is in charge of the Arizona experiment station. to conduct a series of experiments tO settle the matter definitely. He has already finished some of them and has one or two more on which q result has not yet been reached. Dr. F. O. Richmond a well known local veterinarian and one who has been largely instrumental in giv- ing publicity to the theory of the dead liuess of the oleander poison. has as- sisted him bv holding post mortem ex- aminations of the bodies of the dead animals. When all experiments have been completed Prof. Wilson proposes to write bulletin on the subject for issuance bv the territorial university This bulletin will include actual and definite data on the quantity of poison administered. it's effects the death of the animal the nature of the pOisOns and numerous other things that have been definitely established. Sufficient has been learned however to demon strate the deadliness of the poison and the following story of his experiments is permitted. The reader however should note that in this story only general results are given. poison quan- titles are aproXimated etc This is the news story only and the scientific statement of the experiments will come later over Prof Wilson's sigma ture. The animals used in the exper-
  that had passed their days Of real use fitness on the farm and were given the doctor for experimentation. making them martyrs for the benefit of their kind who may live after them.
 The experiments began about two weeks ago and all the animals used were carefully examined and found to be in good health when the expert ments began. Roughly speaking one green oleander leaf weighs about one gramme and the gramme will be re- ferred to as the unit of measurement in this story
 One horse was given ten grammes of green leaves in capsule. In thir- ty-Six hours the horse was dead
 The next horse was given three grammes per day for three or four days. His temperature and pulse be- gan to rise but after the fourth day his condition began to improve His was better and there were evidences Of his ability to overcome the pOison. though he was still ema- ciated Six days after the last of the small doses had been given. ten grains was administered and in sixteen hours the horse was dead. Some of the leaves given were green and some of them dry.
 A COW was given twelve grammes of green leaves and died in thirty six hours
 sheep was given one green leaf. | fnot weighed) and died in forty eight hours. i
 Dr. Richmond made a post mortem examination in each case. He says the
