:.■ ift. By making one extremity of the pile cpmniufflicate 

 wiih the interior of one ear moitiencd with a folution of niu- 

 ■jiate of ammonia, and the other extremity of the pile with 

 the other ear, very ftrong contractions were produced in the 

 mufcles of the face : but the contraolions of the temporal 

 anufcles, the ptei ycoid, and malfeter, were particularly itrik- 

 ing, for they elevated and agitated the low^r jaw with fo 

 ^nnich force, that the gnaililng of the t,eeth;[W:»? difiin«Slly

2d. By eftablifliing a communication between the fpinal 

 jiiarrow and the large nervl fympathetici and vagi armed, 

 and between different regions of the brealt moiflened with the 

 fame folution, and the other extremity of the pile— before 

 the cavities were opened very ftrong tetanic fliutks wer(5k)b- 

 lained tln'oughout the whole body ; fuch violent palpitations 

 •of the heart, that the hand applied on the region of the fifth 

 and lixth ribs was ftrongly iiruck bv them ; inlpiraiions and 

 expirations, w ilh a hifting nqife which accompanied the en- 

 trance and efcape of the air. 



3d. After opening tlie breaft the palpitations of the heart 

 ftill continued, and could be diltinctly perceived : when they 

 had ceafed, they were renewed by eiiablifliing a communica- 

 tion between the h.eart and the pile, the large nervi fympa- 

 thetici and vagi and the pile. 



4th. Bv ar,uiing the abdominal aorta and the plexus coe- 

 liacus, and then making them communicate with the pile by 

 mean-s of tworefpctlive atcs, conlfa6lions were produced in 

 the abdominal aorta.
