Siam and the crooked cross of Bolivia. We had been given excellent seats in the orchestral stalls. Sir Arthur Sullivan conducted his own work. The infant king appeared to be more interested in the electric light installations than in the action or song proceeding on stage, but his mother responded with suitable appreciation to the jokes when they had been explained to her by the Spanish ambassador. This was a musical experience more after my heart than a recital by Sarasate. I laughed heartily, nudged Holmes in the ribs at the saltier sallies and hummed the airs and choruses perhaps too boisterously, since Lady Esther Roscommon, one of my patients, as it happened, poked me from the row behind and courteously complained that I was not only loud but also out of tune. But, as I told her in the intermission, I had never laid claim to any particular musical skill. As for Holmes, his eyes were on the audience, and with opera glasses too, more than on the stage proceedings.
During the intermission, the royal party very democratically showed itself in the general bar, the young king graciously accepting a glass of British lemonade, over which, in the manner of a child unblessed by the blood, he smacked his lips. I was surprised to see that the great Sarasate, in immaculate evening garb with the orders of various foreign states, was taking a glass of champagne with none other than Sir Arthur Sullivan. I commented on the fact to Holmes, who bowed rather distantly to both, and expressed wonder that a man so eminent in the sphere of the more rarefied music should be hobnobbing with a mere entertainer, albeit one honoured by the Queen. "Music is music," Holmes explained, lighting what I took to be a Tangerine panatella. "It has many mansions. Sir Arthur has sunk, Watson, to the level he finds most profitable, and not only in terms of monetary reward, but he is known also for works of dreary piety. They are speaking Italian together." Holmes's ears were sharper than mine. "How much more impressive their reminiscences of aristocratic favour sound than in our own blunt tongue. But the second bell has sounded. What a waste of an exceptionally fine leaf." He referred to his panatella, which he doused with regret in one of the brass receptacles in the lobby. In the second half of the entertainment Holmes slept soundly. I felt I needed no more to experience the shame of an uncultivated boor when I succumbed to slumber at a more elevated musical event. As Holmes had said, somewhat blasphemously, music has many mansions.
The following morning, a hasty message from Sir Edwin Etheridge, delivered while I was at breakfast, summoned me to another consultation in the bedroom of his patient on St John's Wood Road. The young man was no longer exhibiting the symptoms of latah; he seemed now to be suffering from the rare Chinese disease, which I had encountered in Singapore and Hong Kong, known as shook jong. This is a distressing ailment, and embarrassing to describe outside of a medical journal, since its cardinal feature is the patient's fear that the capacity of generation is being removed from him by malevolent forces conjured by an overheated imagination. To combat these forces, which he believes responsible for a progressive diminution of his tangible generative asset, he attempts to obviate its shrinkage by transfixation, usually with the sharpest knife he can find. The only possible treatment was profound sedation and, in the intervals of consciousness, a light diet.
I very naturally turned onto Baker Street after the consultation, the fine weather continuing with a positively Hispanic effulgence. The great world of London seemed wholly at peace. Holmes, in dressing gown and Moorish turban, was rubbing resin onto his bow as I entered his sitting room. He was cheerful while I was not. I had been somewhat unnerved by the sight of an ailment I had thought to be confined to the Chinese, as I had been disconcerted earlier in the week by the less harmful latah, a property of hysterical Malays, both diseases now manifesting themselves in a young person of undoubtedly Anglo-Saxon blood. Having unburdened myself of my disquiet to Holmes, I said, perhaps wisely, "These are probably the sins visited by subject races on our imperialistic ambitions."
"They are the occluded side of progress," Holmes said, somewhat vaguely, and then, less so, "Well, Watson, the royal visit seems to have passed without mishap. The forces
