Not illustrated. 1884 edition. Excerpt: ... Institution Laboratory, Liverpool. Judging from the redness of the stomaoh ar.d intestines that the poison was probably arsenic, a microscopical examination was made, but no particles of arsenic, nor soot, nor indigo were discovered. Mr. Davies, on October 6th, extracted a consideraMe quantity of arsenic from 1 oz. of the contents of the stomach, and converted it into octahedral crystals of Asfiy He then chopped up fine an average mixture containing proportional quantities of the solid portion of the several viscera, and from 1 oz. of the miitore extracted a considerable quantity of arsenic which be identified by conversion into octahedral crystals t AsoOj.

Assuming the weight of the whole abdominal viscera to have been 80 oz., which is a very low figure, the weight of arsenic in the whole must have been, at least, 1'28 grains. Part of the AsjS, was converted into arsenic acid, and precipitated with silver nitrate. The arscniate of silver was thus produced, and afforded confirmation of the identity of the arsenic. Another 2 oz. of the mixed solid viscera was dried and distilled with strong hydrochloric acid; in one half of the distillate arsenic was detected by Marsh test; in the other half arsenic was detected e Reinsch's test. All the materials used in these investigations were first tested for arsenic, and found to be perfectly pm From these results, Mr. Davies gave it as his opinion that sufficient arsenic had been taken to cause death, because arsenic was undoubtedly distributed throughout the whole body, and much of it had been removed by vomiting and purging, as well as by excretion...show more
