183 IsITRITE OF AMYL IN ANGINA PECTORIS. 



Dr. Bennett, thinking the relief of pain by tlie amyl might 

 be due to ancesthesia, ordered chloi-oform to be tried during the 

 attack. 



18th. — About 2 a.m. the pain came on ns usual, and chloro- 

 form was inhaled by the patient. He was only partly put 

 ■under it, and as soon as he again became completely conscious 

 the pain was found to be present as before ; 6 drops of nitrite 

 of amyl were then given by inhalation. The pain disappeared 

 and did not return. 



25th. — The pain came on at 1.58 a.m., but was not very bad. 

 "While it was present the pulse was 100, respirations 32. After 

 amyl was given, but the pain was not quite gone, the pulse was 

 130, it fell with the disappearance of the pain to 100, and twelve 

 minutes after was 80, and tlie respirations 24. 



April 6th. — The pain had come on about 2.35 a.m., and the 

 patient was relieved by a whiff of amyl, but it began to return 

 at the end of the sternum, right ear, and right shoulder. The 

 chest was auscultated, but no abnormal sounds could be 

 detected to indicate any coincident spasm of the bronchial 

 tubes. 



10th. — Patient continues to have the pain every night, and 

 instead of inhaling the nitrite of amyl from a cloth, does so 

 from the bottle. Two or three inhalations usually suffice to 

 relieve the pain. Up to the 8th he used pure nitrite made by 

 Dr, Gamgee, but this being finished, he then began to use some 

 made by Macfarlane & Co., but the smell of it was not so agree- 

 able, and it sometimes occasioned headache, which the pure 

 amyl never did. 



14tli. — The pain has been coming on several times during 

 the night, is most intense at a spot two inches inside of the 

 right nipple, remains there after it has gone from the rest of the 

 chest, and is only removed by repeated inhalation. Last night 

 it came on three times, and was relieved by amyl each time, but 

 five or six inhalations WTie required. To-day at 11 a.m. Jiv of 

 blood were taken from the patient's arm, and he was ordered 

 Potass. lod. gr. viij, three times a day. 



17th. — Pain came on during the night and continued unin- 

 terruptedly for one hour and a half. By Dr. Bennett's order
