nerve. The blood pressure wus teniporiirily imich reduced; respiration 

 was at first inhibited, then increased in power and frequency. In the 

 horse a strong stinudation of the vagus caused death. The pulse was 

 rendered intermittent. Similar results were obtained in experiments 

 with calves. The cow exhibited no inhibition of the heart action, but 

 a gTcat temporary increase. Eserin sulphate increased the force of 

 the heart beat and slowed down its action. Nitroglycerin injected into 

 the horse caused a fall of blood pressure, but increased the amplitude 

 of the cardiac action. Barium chlorid, in doses of 12 grains, increased 

 the force of blood pressure. Stinudation after the administration of 

 this drug had an immediate inhibitive action. When the vagus was 

 cut ])efore being stinudated the action was similar. The dog exhibited 

 an enormous increase in blood pressure and foi'ce of the heart action 

 after treatment with barium chlorid. Atropin sulphate in doses of 

 i grain paralyzed the inhibitive action of the vagus in the dog. 

 When the vagus was subsequently stimulated the blood pressure was 

 increased. A cat treated with large doses of barium chlorid showed 

 a great increase in blood pressure. The cardiac and diuretic effects 

 of barium chlorid were similar to those of digitalis. 



W. Dougherty presented a plan for the foi'mation of a mutual benefit 

 society of the veterinarians of the United States and Canada. After a 

 thorough discussion of the matter a committee was appointed to inves- 

 tigate the desira])ility of forming such a society, and report at the next 

 meeting. 



The by-laws of the association were amended so as to make the time 

 of meeting hereafter the third Tuesday in August in place of the first 

 Tuesday in September. While the place for the next meeting was 

 not definiteh^ determined, the executive committee was requested to 

 consider the proposition to meet at St. Louis. 



During the various sessions of the meeting nearly 1(»0 new names 

 were added to the list of active members.
