A STUDY IN MORBID AND NORMAL PUYSIOLOGY. 3 



Experiment 2. 



Two-thirds-grown rabbit. Put iti the box at 11:30 a.m. Rectal tempcraturu, 104°. 5. 



12 M. — Rectal temperature, 109^. Temperature of box, 112^. 



12:25 P. M. — Rectal temperature, 110^5. Rabbit weak, slobbering a great deal ; breathing with 

 great rapidity. 



1:15 P. M.— Rabbit conscious, lying quietly on his side; not slobbering; breathing uot nearly 

 so rapid, but deep and labored. Rectal temperature, 111^.5. 



1:35 P.M. — Rabbit found dead. Rectal temperature, 112'. 



Autopsy. — Heart: left ventricle empty, very firmly contracted, with a very evident white spot at 

 apex. Galvanic (induced) current very strong, giving rise to no muscular movements whatever, 

 either of heart or voluntary muscles. Blood coagulating slowly and imperfectly ; reaction neutral, 

 or at least so feebly alkaline as to be uncertainly so. Muscular reaction very decidedly acid. 

 Spinal cord not congested. Right side of heart gorged with blood. 



Experiment 3. 



A large adult rabbit. 



12:11 P. M. — Rectal temperature, 105°. Just put in box, whose temperature is 130', heated by 

 very hot brick flues, on which the rabbit lies. 



12:15 P. M. — Rectal temperature, 101°. Breathing excessively hurried. 



12:11 P. M. — Rectal temperature, 109°. 



12:21 p. M. — Rectal temperature, 111°. Had a moment since what was apparently a convulsion, 

 and has had numerous convulsive twitcliings since. Appears serai-uuconscious. 



12:25 P. M. — Dead. Temperature in abdomen after death, 111°. Respiration ceased some time 

 before heart. The thorax was opened, and the heart was felt by the finger to be pulsating. On 

 more complete exposure, the heart was seen to be very distinctly pulsating, and gradually becoming 

 filled with dark blood. The heart was punctured, and blood allowed to escape; it made one or 

 two pulsations, and then at once became rigid. After this the diaphragm was tried with the gal- 

 vanic current, and responded to it. The muscles of the hinder exti-emity did not respond, those of the 

 front legs did. Peristaltic action of the intestines was moderately active when the body was opened, 

 and on galvanic excitation became very active. 



Experiment 4. 



A moderate-sized dog. 



1 p. M. — Put in the hot box. 



1:15 P. M. — Rectal temperature, 10G°. 



1:30 P. M.— Rectal temperature, 110°. 



1:40 P. M. — Rectal temperature, 110°. 75. Just dead. 



Aulojmj. — As soon as respiration ceased, the body was opened. Heart still beating, gorged with 

 dark blood. Veins full of dark blood. Blood on being shaken in test-tubes rapidly clotting, and 

 slowly changing its color to an arterial hue. The vessels were carefully examined ; no clots were 

 found in them. 



Experiment 5. 



An adult pigeon. 



11:40 A. M.— Rectal temperature, 109°. Just put in box ; the temperature in bo.x, 130° ; besides, 

 the pigeon was in direct contact with the very hot brick flue. 



11:45 A. M. Respirations very weak. 



12 M. — Has been unable to stand for some time ; has been semi-unconscious. Just had a convul- 

 sion, followed by persistent opisthotonos. 



12:2 P. M.— Anal temperature, 120° ?. (My thermometer did not mark higher than 120°, to which 

 the mercury rose ; the hand could hardly bear the heat of the flesh.) Dead. Respiration certainly
