ping 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.

"Come and look at this, Jervis," said he.

I wanted no second bidding, being on tenterhooks of curiosity, but came
over and applied my eye to the instrument.

"Well, what is it?" he asked.

"A multipolar nerve corpuscle--very shrivelled, but unmistakable."

"And this?"

He moved the slide to a fresh spot.

"Two pyramidal nerve corpuscles and some portions of fibres."

"And what do you say the tissue is?"

"Cortical brain substance, I should say, without a doubt."

"I entirely agree with you. And that being so," he added, turning to Mr.
Stopford, "we may say that the case for the defence is practically
complete."

"What, in Heaven's name, do you mean?" exclaimed Stopford, starting up.

"I mean that we can now prove when and where and how Miss Grant met her
death. Come and sit down here, and I will explain. No, you needn't go
away, Mr. Felton. We shall have to subpoena you. Perhaps," he
continued, "we had better go over the facts and see what they suggest.
And first we note the position of the body, lying with the feet close to
the off-side door, showing that, when she fell, the deceased was
sitting, or more probably standing, close to that door. Next there is
this." He drew from his pocket a folded paper, which he opened,
displaying a tiny blue disc. "It is one of the sequins with which her
hat was trimmed, and I have in this envelope several more which I took
from the hat itself.

"This single sequin I picked up on the rear end of the off side
footboard, and its presence there makes it nearly certain that at some
time Miss Grant had put her head out of the window on that side.

"The next item of evidence I obtained by dusting the margins of the
off-side window with a light powder, which made visible a greasy
impression three and a quarter inches long on the sharp corner of the
right-hand jamb (right-hand from the inside, I mean).

"And now as to the evidence furnished by the body. The wound in the
skull is behind and above the left ear, is roughly circular, and
measures one inch and seven-sixteenths at most, and a ragged scalp-wound
runs from it towards the left eye. On the right cheek is a linear
contused wound three and a quarter inches long. There are no other
injuries.

"Our next facts are furnished by this." He took up the horn a
