There was an interval of relaxation, but immediately after death the
muscles became very rigid, more so than at rigor-mortis. We afterwards
made a similar series of experiments on some animals with strychnia
itself, both in solid and liquid forms. The symptoms and the results
generally were exactly the same as those I have described in the case of
the other animals.
Cross-examined by Mr. GROVE--I did not see the patient during any severe
attack. I observed that when the animals were touched it brought on the
symptoms. That is a very marked result. Directly they are touched they
give a sudden start, and pass into a severe spasm. At the post-mortem
examination the lungs were very much congested. The muscles generally
were dark and stiff. There was a decided quantity of bloody serous
effusion over the brain. There was a notable quantity, but not a large
quantity, of serum slightly tinged with blood in the membranes of the
spinal cord. The large spinal veins were very much congested, as were
the membranes of the spinal marrow. We opened the head first, and that
led to a great deal of blood flowing from the head. That would make it
uncertain whether the heart was full or empty. The right sides of the
hearts of animals that have been poisoned by strychnia are generally
full. From one to two hours is the longest time in animals at which I
have perceived the first effect of strychnia come on after it has been
taken. I made experiments in conjunction with Mr. Nunneley, and my
impression is that the interval has been as long as one hour. I
discovered strychnia with all the tests I applied with more or less
distinctness. I have detected strychnia in the stomach two months after
death, and after decomposition had proceeded to a considerable extent.

Re-examined by the ATTORNEY-GENERAL--I have given to the animals which I
have killed from half a grain to two grains. The animals experimented on
were cats, rabbits, and dogs. The strychnia, I think, acts on the
nerves, but a part may be taken into the blood also and act through the
blood. The poison is absorbed. We searched the stomach to find the
presence of the strychnia. The strychnia which we found in the stomach
would be that which was there in excess beyond that which had been
absorbed in the system. The strychnia that has been absorbed into the
system is sufficient to destroy life. The excess that remains in the
stomach is inactive. I should expect to fail sometimes to find strychnia
in the stomach if the minimum quantity capable of operating to the
destruction of life had been administered. If death resulted from a
series of minute doses of this poison, administered for a space of
several days, it is my opinion that the appearances would be likely to
be different after death from what they would, supposing death was
produced rapidly by one dose.
