His task isr therefore, very difficult, especially when rn^ny of the poisons except corro- sives and irritants do not show any characteristic post-mortem signs and when bodies are in an advanced state of decomposition. In cases where positive signs of poisoning are not manifest, the medical officer should not give a definite opinion regarding the cause of death, but should suggest that the viscera be forwarded to the Chemical Examiner for analysis. He must carry out, in all the cases of suspected poisoning, a thorough examination o£ the body, bofti external and internal, as far as possible. External Examination,—Some poisons, such as hydrocyanic acid, car-r bolic acid, chloroform, ether, opciBaa, etc. give off a peculiar smell on opening the body. Hence no odorous disirfe^feaaat that is likely to mar such should be used. "Rie surface &&,4te body and Hie: ci*es m&$ stow or marks of vomit, fseces ^fl&flpet poison itself.
