Poisons leave clues
Poisons Leave Clews Tim and again, when a man Is on trial for his life, there appears as one of the witnesses for the prosecu- prosecu- tion the Home Office expert, the man who often throws the greatest possl- possl- ble light upon the cause of the tragedy. "When there is doubt about any one's death the post-mortem post-mortem post-mortem examination is the first step in solving the problem. The body is thoroughly searched for any external signs, as scratches, bruises and cuts, that would be likely to cause, death. If this inspection fails, and the body i3 otherwise healthy, poison is naturally suspected. The stomach and certain other parts are then placed in glass jars, sealed and sent to the analyst. . Some poisons are easily detected. Oil of vitrol, for instance, burns the mouth and throat, leaving black stains. nt tha offpots of noisons are often Vvery like those of disease, and a most ' ft refill examination has to be made. says Pearson's Weekly, ; The analyst begins his examination by making a series of "brews," boiling, filtering, and distilling the matter he is investigating. He uses firing this time various "agents," as they are called, called, which separate the different classes of poison. This work often takes days of constant labor to' perform, the time varying according to the kind of poison, prusslc acid, for instance, being much easier to detect than strychnine. If his various tests fall, what is left of the animal matter Is mixed with hydrochloric acid and distilled again, after which he knows that the body contains no poison save a metallic one. In his inquiry the expert has made a number of decoctions, each of which is tested in turn. Suppose he Is testing one. A little of the "brew" is placed In a small glass test tube with some distilled water. Hydrocholic acid is carefully dropped in. If silver, mercury or lead Is present a powder Is formed. If nothing happens the analyst tests again with other agents for certain groups of metals. At last he notices notices a change, and knows that the poison he Is after belongs to one of three or four. As an Instance, his search shows that the poison is either arsenic, tin or cadmium. He boils the "brew" again, and adds some strong ammonia, and finds the powder in the liquid has disappeared. He is now certain of arsenic! But the life of a fellow being is hanging on results, and he must be sure beyond all doubt. A famous spe-- spe-- clal test for arsenic is known as Relnsch's and this he . tries. A little of the suspected liquid is placed in the test tube with some hydrochloric acid. A email piece of copper is dropped in and the liquid warmed. Arsenic and f" copper are madly in love wljh each other, and every scrap of the poison in the tube flies to the copper and V covers It with a gray coat Flaal Teat. '-is The -copper -copper Is taken out, washed. ' flrled and placed In a glass tube, and the whole heated. The gray deposit disappears, and the arsenic is found clinging in crystals to the glass. This test is final, and has brought more than one murderer to the scaffold. It is easy to see that an analyst's task Is not an easy one. Not only must he-try he-try he-try and find the actual poison, but often It Is necessary to discover the actual quantity used. An instance of thi3 may be recalled. The wife of a surgeon died from corrosive sublimate poisoning. The surgeon administered the suspected draught, and he asserted that he mistook mistook the bottle of mixture prepared for a sailor for the water bottle. The sailor's mixture was analyzed and found to contain corrosive sublimate. sublimate. The analyst measured the quantities present, and discovered that the mixture contained only 10 grains to an ounce of liquid, while the draught contained 15 grains of poison to the same quality, showing that the surgeon had lied! A suit of dirty clothes, with a few small, rusty-looking rusty-looking rusty-looking spots. Are they blood? The piece of cloth Is cut out and put in a small quantity of distilled water. With the aid of the spectroscope spectroscope the expert ascertains that It Is blood and not paint -or -or iron-mold. iron-mold. iron-mold. The spectroscope merely tells him that it is blood, but not the kind. Here the microscope comes in and leads the investigator a step further. It is, however, however, never safe to say whether the blood is human or not; all that can be said with certainty Is that It is the blood of a mammal. 4 AT THE HOTELS James Harned of Enid is at the Eaton.

In these days when the ground hog finds few to do him reverence it is a breach of professional comity for the equinoctial tempest to fail to come to time.
