vasti and gluteal muscles, soon extending to all the hind limbs, and 

 afterwards to the whole body ; slight ptyalism and grinding of the jaws ; 

 ears and extremities cold. At 3 p.m. temperature 39"8° C. ; respiration 

 and circulation slightly disturbed ; generalised trembling ; somnolence. 

 The symptoms afterwards disappeared. 



(8) A horse, weighing 533-^ lbs., received at g a.m. on the nth 

 March an injection in the jugular vein of fifteen and a quarter fluid 

 drachms of a 5 per cent, iodine solution ('07 grain per pound of body- 

 weight). Before injection temperature 38*0° C, respirations 17, pulse 

 45. During the succeeding two hours the temperature rose appre- 

 ciably ; the respiration and circulation became more rapid. At 

 11.30 a.m. muscular trembling, salivation, grinding of the jaws, cough, 

 and slight weeping appeared ; these troubles persisted for two or three 

 hours. At I p.m. temperature 39"i° C, respirations 30, pulse 78; the 

 respiration suggested dyspnoea. An hour later the trembling dimin- 

 ished ; the circulation and respiration became slower, and the tempera- 

 ture fell. No after complications. 



(9) A horse, weighing 682 lbs., received at 3 p.m. on the i8th March 

 in the jugular vein seventeen fluid drachms of a 5 per cent, solution of 

 iodine ("07 grain per pound of body-weight). Before injection tempe- 

 rature 38*2° C, respirations 18, pulse 46. At the end of half an hour 

 slight salivation, grinding of the jaws, and acceleration of breathing 

 (twenty-five per minute). At 4 p.m. trembling, especially marked in 

 the hind limbs and face ; passage of hard faeces and flatus. Tempera- 

 ture 38*7° C. ; respirations 22 ; pulse 45. At 5 p.m. passage of fasces 

 moister than on the preceding occasion ; the passage of flatus and the 

 trembling persisted. Temperature 39' 1° C. ; respirations 15 ; pulse 42. 

 At 6.10 p.m. passage of haemoglobinuric urine ; slight trembling. At 

 7 p.m. the animal appeared a little depressed, but otherwise showed 

 nothing abnormal. 



(10) A horse, weighing 902 lbs., received at 2.50 p.m. on the 21st 

 March an injection in the jugular vein of twenty-two fluid drachms of 

 a 5 per cent, iodine solution ("07 grain per pound of body-weight). 

 Before injection temperature 38° C. ; pulse 38 ; respirations 10. At 

 the end of a quarter of an hour grinding of the jaws and salivation ; 

 expulsion of flatus. Fifteen minutes later temperature 38"5° C. ; pulse 

 38 ; respirations 18 ; respiration difficult, expiration irregular. Trem- 

 bling attacks, at first localised in the crural and gluteal muscles, after- 

 wards generalised ; signs of depression. At 3.30 p.m. more abundant 

 ptyalism ; spasmodic contractions of the jaws ; stamping and signs of 

 excitement alternating with periods of depression ; passage of soft 

 faeces ; strong and persistent borborygmus. At 4 p.m. temperature
