Would its being found in the blood enable you to form any opinion how shortly before death the antimony had been given?--It is impossible to say with any precision, but I should say shortly before death--within some days; the longest period known at which antimony has been found in the blood, after a person has ceased to take it, was eight days. I heard the account by the servant girls of the vomiting of Mr. Cook; I also heard the account given of his vomiting at Shrewsbury, and by the medical men, Gibson and Jones, and Dr. Bamford’s deposition as to the concomitant symptoms. In my opinion, the vomiting would be such as might be produced by antimony. Tartar emetic is soluble in fluids, and if mixed with broth or toast and water would not affect the colour.
From these traces of the antimony can you form any judgment as to the time when the antimony was taken?--It is impossible to say with any precision, but I should say within two or three weeks at the outside. We did not find any perceptible quantity dissolved in the fluids of the body and the washings of the stomach; therefore I should infer there was no evidence of any given within some hours of death. I think that which I found in the liver might have been administered within eighteen hours of death or within two days. I know by experience it takes a shorter time to get to the liver. Antimony does not affect the taste of anything if it is given in quantities which would cause vomiting. If a large quantity was taken at once it might leave a choking or constricting sensation, as if the throat was contracted. There was no trace of mercury. I should have expected to find mercury according to the quantity taken. If a few grains had been taken recently before death I should expect to find some trace in the liver. Supposing a man had been taking mercury for any syphilitic affection within anything like a recent period before death I should expect to find it. I heard the evidence which was given as to the deaths of Mrs. Smith, Agnes French, and the lady referred to, and also the case of the gentleman of whom Mr. Moore spoke. Judging by the results of my own experiments and studies, I agree that those deaths were occasioned by strychnia. Mr. Cook’s attacks appear to me to be of a similar character.
