"Lord bless you, sir," laughed Mr. Felton, "they haven't got no feeling in their horns, else what good 'ud their horns be to 'em?"

Apparently he was right, for the second steer was as indifferent to a sounding rap on either horn as the first. Nevertheless, when Thorndyke approached the third steer, I unconsciously drew nearer to watch; and I noticed that, as the stick struck the horn, the beast drew back in evident alarm, and that when the blow was repeated, it became manifestly uneasy.

"He don't seem to like that," said the butcher. "Seems as if—Hullo, that's queer!"

Thorndyke had just brought his stick up against the left horn, and immediately the beast had winced and started back, shaking his head and moaning. There was not, however, room for him to back out of reach, and Thorndyke, by leaning into the pen, was able to inspect the sensitive horn, which he did with the closest attention, while the butcher looked on with obvious perturbation.

"You don't think there's anything wrong with this beast, sir, I hope," said he.

"I can't say without a further examination," replied Thorndyke. "It may be the horn only that is affected. If you will have it sawn off close to the head, and sent up to me at the hotel, I will look at it and tell you. And, by way of preventing any mistakes, I will mark it and cover it up, to protect it from injury in the slaughter-house."

He opened his parcel and produced from it a wide-mouthed bottle labelled "Ox-gall," a sheet of gutta-percha tissue, a roller bandage, and a stick of sealing-wax. Handing the bottle to Mr. Felton, he encased the distal half of the horn in a covering by means of the tissue and the bandage, which he fixed securely with the sealing-wax.

"I'll saw the horn off and bring it up to the hotel myself, with the ox-gall," said Mr. Felton. "You shall have them in half an hour."

He was as good as his word, for in half an hour Thorndyke was seated at a small table by the window of our private sitting-room in the Black Bull Hotel. The table was covered with newspaper, and on it lay the long grey horn and Thorndyke's travelling-case, now open and displaying a small microscope and its accessories. The butcher was seated solidly in an armchair waiting, with a half-suspicious eye on Thorndyke for the report; and I was endeavouring by cheerful talk to keep Mr. Stopford from sinking into utter despondency, though I, too, kept a furtive watch on my colleague's rather mysterious proceedings.

I saw him unwind the bandage and apply the horn to his ear, bending it slightly to and fro. I watched him, as he scanned the surface closely through a lens, and observed him as he scraped some substance from the pointed end on to a glass slide, and, having applied a drop of some reagent, began to tease out the scraping with a pair of mounted needles. Presently he placed the slide under the microscope, and, having observed it attentively for a minute or two, turned round sharply.
