Are you of opinion, as a chemist, that where strychnia has been taken in a sufficient dose to poison, it can be detected, and ought to be detected?--Yes, up to the time the body is decomposed completely. Even where there is putrefaction--where the body has become a dry powder. I am of opinion that strychnia ought to have been detected if it had existed in the jar containing the stomach, even in the state it then was. Cross-examined by the ATTORNEY-GENERAL--Until lately my experiments for the purpose of finding strychnia have been principally in the stomach. In two cases I found it in the tissues of the animals. One was the second cat, the other a dog to which I gave the large dose of one grain. Judging from reports in newspapers, I have said in conversation that strychnia had been given, and that “If it was there, Professor Taylor ought to have found it.” [Sidenote: W. Herepath] Re-examined by Mr. GROVE--What is the smallest quantity you have detected in the tissues of the stomach?--I am satisfied that you could discover the fifty-thousandth part of a grain that is unmixed with organic matter. I dissolved the tenth part of a grain in a gallon of water, that is 1 in 70,000. I can take the tenth part of a drop of the water and demonstrate the presence of strychnia. What is the smallest portion of strychnia when mixed with organic matter you can detect?--I took about an eighth part of the liver of a dog, and from that I had enough to make four distinct experiments with the four tests. So that you experimented on a thirty-second part of the liver?--Yes. * * * * * [Sidenote: J. E. D. Rogers] Mr. JULIAN EDWARD DISBROWE ROGERS, examined by Mr. GRAY--I have been sixteen years Professor of Chemistry at St. George’s School of Medicine, in London. I made an experiment with one dog with a view of extracting strychnia from the body. I gave it two grains of pure strychnia between two pieces of meat. Three days after it was dead I removed the stomach and its contents, and took some of the blood. I analysed the blood ten days after its removal from the body, when it was putrid, and found strychnia by the colour tests. About a month or five weeks afterwards I analysed the stomach and its contents, and strychnia was separated in a large quantity. Having heard the evidence as to the stomach and its contents in this case being put in a jar and sent to London, in my judgment strychnia, if it had been administered, must have been found in the contents of the stomach. Cross-examined by the ATTORNEY-GENERAL--I have only made one experiment with strychnia on this dog. Do you think it would make any difference if the contents were lost?--If there were no contents spread over the intestines, then that would make a difference. If they had been spilt and shaken, then it would make no difference.
