Will you explain that more simply to the jury? — The poison would paralyse the muscles of the throat and chest, and the victim would be unable to breathe and would die of suffocation.
You have seen that Dr Hughes mentioned in his evidence that the pupils of the eyes were slightly contracted when he first saw the body. What conclusion do you draw from that? — I cannot definitely say. Myosis (that is, contraction of the pupils) is characteristic of the effects of certain poisons, including muscarine, but the contraction usually disappears at death, though, curiously enough, in the case of eserine, a pronounced myosis has been found five hours after death. I should regard a slight degree of contraction as consistent with muscarine poisoning, but not, in itself, conclusive evidence one way or another.
Have you ever seen a case of muscarine poisoning? — I have seen perhaps half a dozen cases in my own experience, mostly among children who had eaten the Fly Agaric in mistake for an edible mushroom. One case, I remember, was brought to the hospital too late for anything to be done, and the patient expired in convulsions after a period of unconsciousness. Three or four were treated by the injection of atropin and recovered completely. Another case was not brought to my notice till after the symptoms had cleared up of their own accord; in this case the amount eaten was very small.
Such cases are not always fatal? — By no means. If the proper treatment can be given immediately, the prognosis is favourable. Without such treatment, however, and where a large quantity of the poison is consumed, recovery would be less likely.
The Coroner: In your opinion, what was the cause of death in the case of Mr Harrison?
Sir James Lubbock: I have not the slightest doubt that he died of poisoning from muscarine, taken in the dish of fungus submitted to me for analysis.
Sir James further added that the Fly Agaric, Amanita muscaria, was frequently found in woods and sheltered places, and was liable to be eaten in mistake for another member of the same family, Amanita rubescens, or Warty Caps, an edible fungus which it very closely resembled.
Reference was made to the Government publications, Edible and Poisonous Fungi, and to the book Neglected Edible Treasures, written by the deceased, and pictures of the fungi in question were passed round among the jury.
Questioned with regard to the eggs, bread, coffee, whisky and other articles of diet found in ‘The Shack’, Sir James said he had subjected them all to careful analysis, without discovering anything of a deleterious character.
DECEASED SEEN GATHERING FUNGI
Dr Hughes of Bovey Tracey, who performed the autopsy, said that he had found the heart of the deceased very greatly dilated, a symptom characteristic of poisoning by Amanita muscaria.
Harold Coffin, a labourer, gave evidence that he had met with deceased on the morning of October 17th. He had a satchel slung over his shoulder, and appeared to be searching for something on the ground. The time would be about 8 a.m. Deceased was then entering a small wood situated in the valley below Manaton. The witness had frequently seen deceased wandering about the country, sometimes with a sketching-easel and sometimes gathering plants and roots. Deceased had sometimes conversed with the witness about making a meal of unnatural things, such as nettles and toadstools, and witness had always supposed him to be a little peculiar in his head.
Henry Trefusis, a carrier, stated that he had delivered a loaf of bread, a pound of shin of beef and other provisions to ‘The Shack’, at 10.30 a.m., on Thursday, October 17th. Deceased had called out to him from the outhouse to put the goods on the window-sill. As far as he could see and hear, deceased was then in his usual health and spirits.
Mr Lathom, recalled, confirmed his previous statement that Mr Harrison had spoken to him on the Wednesday evening about his intention of gathering fungi the next day, and had mentioned a name resembling ‘Warty Hats’ or ‘Warty Caps’.
The coroner, in summing up the evidence to the jury, laid stress on the danger of experimenting in unusual articles of diet. It was notorious, he said, that other nations, such as the French, were accustomed to eat many natural products, such as frogs, snails, dandelions and various kinds of fungi, which in this country were considered unfit for human food. Such experiments, when conducted by highly expert persons, might sometimes turn out well, but, on the other hand, nobody was infallible, and undoubtedly a wise caution was in most cases to be preferred. Sir James Lubbock had cited some very sad instances of unfortunate children who had succumbed to the effects of accidentally eating those dangerous toadstools which unhappily grew in such great profusion in many parts of the country, and he would like to urge on all parents the advisability of strictly forbidding their boys and girls to tamper with anything which they might pick up on their rambles. The present case would serve as a terrible warning, which he hoped would not soon be forgotten. It was most unfortunate that, owing to the remote situation of ‘The Shack’ and the unlucky absence of Mr Lathom in London, there should have been no help at hand when the deceased was overtaken by this terrible accident. The circumstances of his lonely and agonising death were such as to arouse the deepest compassion for the widow and son of the deceased.
The jury, after a few minutes’ consultation, brought in a verdict of Accidental Death, due to poisoning by Amanita muscaria. The foreman said that the jury desired to express their deep sympathy with the bereaved family. They would also like to add a rider to the effect that teachers in the schools of the surrounding districts should be encouraged to warn their pupils against the eating of toadstools, and that charts displaying the various kinds of poisonous fungi should be hung in the classrooms.

49. Statement by Paul Harrison
I was in Africa when the news of my father’s death reached me. The work on which I was engaged was nearly completed, and I at once made arrangements for handing over the concluding portions of the job and returning to England. It took a little time to settle all this and to arrange for my journey to the coast, and it was not till the 6th of January, 1930, that I arrived in London.
From the moment that I heard the cause of death assigned, I was positively convinced that there was no accident about it. My father’s expert knowledge of fungi was very great; and he was a man of almost exaggerated precision in matters of this kind. It was entirely incredible to me that he could ever have mistaken a stool of Amanita muscaria for Amanita rubescens, even in the gathering of it; far more so that he could have peeled and prepared the fungus for eating without noticing the difference. To the average coroner’s jury, accustomed to dealing with schoolchildren and trippers, such a mistake would no doubt seem perfectly natural; but my father was no more likely to take muscaria for Rubescens than to take a piece of cast-iron for a piece of chilled steel. I immediately scouted the whole idea of accident. Two possibilities remained for me to investigate. Either my father, in his unselfish devotion to the worthless woman he had married, had destroyed himself by a painful method which would look like accident and so disarm suspicion; or else he had been murdered. In either case, I was determined that the woman should not benefit by the crime which she had caused.
