lUO Sramm6S you SalC, ulu you nOG 16S, sir and now propose to estimate on the re- mainder, witness replied
 Mir. Cassidy objected to an estimate He submitted that what it ought to be was demonstration based upon an actual analysis.
 The court ruled the witness evidence ad- missible as the usual method of making and computing these examinations.
 Mir Cassidy-Will your honor be good enough to note an exception to your ruling
 Witness proceeded-T calculate that the entire 603 grains of sampled matter contained 15S-10O0 of one grain of the whole oxide of
 arsenic. I then proceeded to examine the
 arsenic to make sure that 1t was arsenic. 1 took nitric acid solution and evaporated 1t to dryness. It left white residue. This white residue I dropped in water, and added little solution of nitrate of silver which gave
 heavy brick-dust red precipitate of arsenate of silver, soluble in ammonia and nitric acid. Exhibit No. shown This identifies the
 substance as arsenic without a shadow of doubt.
 next weighed out 1O6 grammes of the sample stomach mixture equals 323 and 25- 100 grains this quantity I tested in the same | manner as the preceding; l weighed the metallic arsenic and found 1t to weigh l and | 35-100 of milligram
 l To Mir. Jones-A milligram is the one l thousanhth part of a gramme; in one gramme l there are 154 grains. This demonstrated to ny uluu lutt tu0 Stlu pllnS was comp ] and the arsenic evenly distributed through | the mass. That Exhibit No. 2l, the Dr. l Marsh test arsenic, put back in the Marsh apparatus. Then there still remained 43 l grammes of the stomach mixture; Ioxydized | this in the same manner as described and ob- l tained from 1t the metallic arsenic. This | solution I took and evaporated; obtained 8 | white residue of arsenic acid; dissolved it in 1 water containing sulphurlc acid reduced the l arsenic acid to arsenious acid by boiling it in l solution of sulphide this solution I treat 1 ed with hydrogen sulphide gas and obtained l yellow hocculent precipitate of arsenious sul- 1 phide constituting exhibit No. 3. This is I another proof that the substance found is 1 arsenic
 1 To Mir. Doolittle-I have large number of proofs to show that the substance is ar | senic.
 l The contents of the jar containing the liver | weighed 1, ,482 grammes-equal to pounds 4 ounces and 12O OS grains. Of this 420 l grammes were treated for organic poisons; 1 none was found. I examined another DOT
 tion of 3S0 grammes by another process for
 organic poison and obtained no result. I then l took 2O9 grammes and examined them for l arsenic and obtained metallic mirror which l I did not weigh. This I treated with dry hydrogen sulphide gas, heating the mirror of
 the deposit very gently. It changed color,
 becoming of a bright yellow, namely, arsen-
 ated hydrogen, another proof that the sub- ! feet found was arsenic. This is exhibit No. 10, arsen1ous sulphide formed from metallic
 arsenic, having bright yellow lustre Prof. l c showed the result upon the frame to the jury One juror in the back tier stepped
 down to get distinct view.
 Witness continued-I next took no l grammes (equal to 3 oz. and g. S5 grains) of
 the liver mixture. This I oxydized and ob- | tained 8 mirror of metallic arsenic that
 weighed 40 of one milligramme. From l this I calculate that the whole liver mixture l contained 1O9 1000 of one grain of the
 white oxide of arsenic. This arsenic put
 back in Marsh apparatus and obtained a portion of it as metallic arsenic, which forms
 exhibit No. r. Exhibit shown by the chem | ist to the jury.
 The rest of the arsenic from this portion
 was obtained as black deposit on porcelain by holding portion of the surface over a jet of flame in the Marsh apparatus and with I drawing the heat from the glass tube shows
 how and MT. Case stepped up and examined. ] 1 In that way I obtained & number of small black deposits, and it proves that the sub- | stance was arsenic; I first treated 1t with vel low ammonium sulphide and they did not | dissolve but when dried down they gave a I bright yellow deposit-arsenious sulphur. l Other stains treated with sodium hydro chlo 1 ride dissolved readily and completely again | showing that the substance undoubtedly
 arsenic. Another portion of liver mixture, ] 163 grammes, was examined for mineral poi
 sons generally, including arsenic. From this
 I obtained eighteen millegrammes of OK l idle of iron, from which I calculate that the | entire liver mixture contained , and 52-100 of
 grain of oxide of iron. This oxide of iron l l dissolved in hydro-chloric acid and have it
 as exhibit 14 shown chloride of iron from
 the iver." commonly called muriate of iron. 1 I eliminated from this exhibit No, 13 of me- l ta11ic arsenic There remained 200 prammeS 1 Of the sample mixture, which l treated with nitric and sulphuric acids and obtained anoth- l CT deposit of metallic arsenic. This dissolved in nitric acid left 8 white residue of arsenic l acid by evaporation this dissolved in water ! containing sulphuric acid was then diffused
 to arsenious oxide by boiling with arsenious | sulphide and then precipitated by hydro-sul-
 phide gas. The result is shown in exhibit 1 No. 8. Exhibit shown the jury.
 The intestines weighed 1,471 grammes, or I pounds, 3 ounces and 3S8 52 grains. Three
 hundred gramlnes heated like the other spec
 imens yielded no organic poison, and this l test with the others convinced witness there 1 was organic poison in the body. Two
 hundred grammes treated for arsenic yielded
 2 1-1O milligrammes of metallic arsenic | equal to PIT milligrames of the white oxide 1 of arsenic. The whole contents of the jar 1 contained (by estimate from test) .3l4 grains 1 white oxide of arsenic. It was exhibit No. l 15.
 The witness next examined G71 more 1 grammes of the intestines and extracted 12 ? millgrammes sulphide of arsenic. Another sample of 15O grammes of the intestines was
 treated for sulphide of arsenic. The remain | ing 15O grammes were treated for metallic
 arsenic and the result formed exhibit IF. The kidneys weighed $40 grammes, or pound, 3 ounces and 20 99-1OO grains. The | dried kidney-with the alcohol evaporated- weighed 63 grams, equal to ounces 4O5.O8 grains.
 The entire amount of both kidneys was oxydized and there was obtained 1.50 milli- grams of metallic arsenic. That Is equiva- lent to l 9-1O milligrams of the white oxide of arsenic, which is equivalent to 29-1OOO of a grain of white oxide of arsenic. That arsenic was again put back in the Marsh ap- paratus and obtained as metallic arsenic The
 professor described further. The result was sulphide of arsenic, labeled exhibit Is, ar senic partly converted into arsenious sul- phide. This result showed that the alcohol used was free from arsenic. Another opera tion was performed. Portions of the nitric acid and sulphuric acid, some of the distilled water, some of the filter paper, etc., were taken and subjected to the required tests, the result being that they were shown to be free from arsenic. The result was shown in ex- hibit 19, showing that all the chemicals used in the analysis were absolutely free from any trace of arsenic.
 The jar containing lungs, heart and spleen was opened. The portions of heart and the alcohol were analysed together, and the DOT tions of lung and spleen together The weight of the portion of the heart and the alcohol with it was III grains, equivalent to oz., 217 5G-1OO grains The heart portion dry weighed 33 grams, equal to oz T 3-4 grains. The metallic arsenic obtained weighed 40 milligrammes That is equivalent to 1 S48-10OO of a milli gramme of the white oxide of arsenic, which was equivalent to 2S 1000 of grain of white ! oxvde of arsenic That is exhibit six.
 The lung and spleen, moist with alcohol, | weighed 331 grammes, equivalent to II oz. l 295 AS 1000. From the sample mixture 100 l grams gave 1 7-1O millgrammes of metallic l arsenic equal to 3 PA 1000 of milligramme | of the white oxide of arsenic. A second 100 l grams of lung and spleen gave similar mir | TOT of metallic arsenic. They are exhibits l and respectively. The remaining 131 grams of tissue of lung and spleen were oxydized l and metallic arsenic was obtained, and this l gave 2-1O milligrammes of metallic arsenic. 1 Two tests were made revealing arsenic. An analysis of the portion of the brain was then detailed The result was POO grams aof the sampled substance gave 7-1Oth of milligramme of metallic arsenic. From this the professor computed that the
