TOXICOLOGICAL CHART. 



ated pulse, untranquil respiration, intestinal 

 ii-ritation, Avhich, if followed by purging, 

 alfords relief; if not, these symptoms be- 

 come more urgent, the body is covered with 

 ])crspiration, saliva is secreted in increased 

 quantities, the legs become deathly cold, 

 inflammation of the bowels supervenes, and 

 death. 



Treatment. — A free use of demulcents. 

 ]\Iilk has been strongly advocated ; on what 

 grounds beyond that of its being a bland 

 fluid, I am at a loss to conjecture. Olea- 

 ginous purgatives ; counter-irritants. 



Morbid Appearances. — The villous coat 

 of the stomach will be found inflamed; the 

 intestines also in a high state of inflamma- 

 tion, particularly the caecum and colon; the 

 heart pale and flabby ; and the lungs con- 

 gested. 



Tests. — None definite. 



AGENT. 



NICOTIANA TABACUM. 



Tobacco. 



Symptoms. — Nausea, giddiness, coma, 

 feeble and irritable pulse. Sometimes gen- 

 eral excitement of the system, profuse per- 

 spiration, labored respiration, pulse much 

 quickened, partial insensibility. 



Treatment. — Expulsion of the agent by 

 purgatives ; diffusible stimulants when coma 

 exists ; demulcents. 



Morbid Appearances. — I am not ac- 

 quainted with an instance of death having 

 taken place, although this agent is fre- 

 quently given as a vermifuge in very large 

 quantities. 



Tests. — None definite. 



AGENT. 



JUNIPERUe SABINA. 



Savin. 



Sy7nptoms. — This, like the preceding 

 agent, is given as a vermifuge, and some- 

 times incautiously. Gastric irritation is 

 then evinced, the animal refuses food, and 

 is languid ; this is followed by diuresis, and 

 sometimes by purging ; the pulse becomes 

 irregular and full, and the respiration hur- 

 ried. 



Treatment. — Expulsion of the agent 

 from out the alimentary canal by oleagi- 

 nous purgatives ; demulcents. 



Morbid Appearances. — Esophagus and 

 stomach inflamed, particularly the villous 

 portion of the latter viscus, on which patches 

 of extravasated blood are seen to exist ; the 

 small intestines contain miuch raiucus, and 

 are slightly inflamed ; lungs congested ; 

 larynx and trachea of a rusty yellow color ; 

 glands at the root of the tongue much 

 enlarged. 



Tests. — The partially digested vegeta- 

 ble matter found in the alimentary tube, 

 which may be distinguished by its odor. 



Under the head of Narcotico- Acrid Poisons, perhaps, should be placed the Atropa 

 Belladonna, Deadly Nig-htshade, which, in large doses, induces singultus, a dilatation 

 of the pupils, feeble and irritable pulse, and a relaxed state of the bowels. Also many 

 of the umbelUferous order of plants, as Conium Maculatum, Common Hemlock, the 

 influence of which is probably that of a Narcotic ; Cicuta Virosa, Water Hemlock, 

 which, to some animals proves an energetic Poison ; wdth a few of the natural family 

 of the Ranunculaca3, as the Aconitum Napellus, Monkshood, and Helleboris Niger, 

 Black Hellebore, which cause death by irritation, producing gastro-enteritis, followed by 

 delirium; likewise Delphinium Staphysagria, Stave sacre ; Bryonia Alba, Wild-vine 

 or Bryony, and Felis Foemina, Female Fern; of which latter very large quantities are 

 required to effect any marked change in the animal system ; and, indeed, it may be said 

 of the Vegetable Poisons generally, that the Horse is enabled to resist the influence
