humours rather more than one-thirty-secoud of a grain ; and the lenses be- 

 tween one-thirty-second and one-sixty-fourth of a grain to a litre of water. 



21. Another guineapig was killed in eight hours after taking five grains 

 of sulphate of quinine, in two doses, wath half an hour's interval. The ex- 

 tract of its tissues was compared with pig 8, which had taken no quinine, and 

 with pig 1 6 and pig 24, which were killed four hours and thirty-two hours 

 after taking five grains of quinine ; the fluorescence of the liver was very 

 strong ; the muscles, the brain, and the kidneys showed the fluorescence 

 very distinctly ; the fluorescence of the urine equalled from two-fifths to 

 three-fifths of a grain of quinine ; the bile was not more than one-twentieth 

 of a grain of quinine ; the blood fluoresced more distinctly ; the lenses and 

 the humours not so much, and the nerves least of all. 



This pig was with young when killed, and the fluorescence of the foetus 

 was distinct ; the fluorescence of the liquor amnii was less than that of 

 the foetus. 



22. Another pig was killed in twenty-four hours after taking four grains 

 of sulphate of quinine. The fluorescence of its textures was compared with 

 pig 6, that had taken no quinine ; the fluorescence of the liver and kid- 

 ney was equal to half a grain of quinine ; the blood and bile fluoresced 

 equal to one-eighth of a grain ; the urine between one-eighth and one-six- 

 teenth ; the muscle the same ; the brain and the humours rather less than 

 one-sixteenth of a grain ; the lenses and the nerves about one-thirty-second 

 of a grain of quinine to a litre of water. 



23. Another pig was killed twenty-four hours after taking six grains of 

 quinine, in three doses, with 20 minutes' interval. The fluorescence was 

 compared with pig 3, which had taken no quinine ; the liver showed the 

 most[fluorescence ; the muscles, the kidney, and the brain were next ; the 

 nerves and blood equalled about one-tenth of a grain of quinine, and the 

 lenses fluoresced least of all. 



24. Another pig was killed thirty-two hours after taking five grains of 

 sulphate of quinine. The fluorescence was compared with pig 4, which had 

 taken no quinine ; the liver fluoresced scarcely more than that of the pig 

 that had taken no quinine, about one-twenty-fifth of a grain to a litre of 

 water ; the kidney fluoresced a little more than that of the pig without 

 quinine ; the fluorescence of the urine was scarcely perceptible, less than 

 one-fiftieth of a grain of quinine ; the muscles a little less than the pig 

 without quinine ; the blood, the nerves, the brain fluoresced very slightly; 

 the lens and the humours more than any other part. 



25. x\nother pig was killed forty-eight hours after four grains of sul- 

 phate of quinine. The fluorescence was compared with pig 6, which had 

 taken no quinine ; the extract of the liver and of the blood had a fluo- 

 rescence equal to one- sixteenth of a grain of quinine in a litre of water; 

 the bile, the kidney, the urine, the brain, the lenses, the humours, the 

 nerves, and the muscles had each a fluorescence less than one-thirty-second 

 part of a grain of quinine.
