    [Beprinted from the 'Medical Society's Proceedings; Vol. X] OK A CASE OF FITS EESEMBLIKa THOSE AETIFI- CIALLY PEODUCED IN GUINEA-PIGS. By J. HuGHLiNGS Jackson, M.D., LL.D., F.R.S. This is tlie case of a boy who has fits when his head is touched: The case is in many respects very like that of againea-pig rendered epileptic by some operation on its spinal cord or sciatic nerve (Brown-Sequard). The patient has an epileptogenous zone, as the guinea-pig comes to have some time after the operation.* Before going further, I would remark that, using the term epilepsy generically, there are, I think, three classes of epileptic fits:—(1) epilepsy proper; (2) epileptiform seizures; (3) fits depending on discharges beginning in parts of the pons Varolii and medulla oblongata.f The fits my patient have belong, I think, to the third class. In there being persistent local disease (as evidenced particularly by the hemiplegia), the case very much resembles the cases of Brown-Sequard's guinea-pigs, and closely in that there is an epileptogenous zone. I say little of Brow^n- Sequard's researches on epilepsy, because Mr. Victor Horsley has recently repeated this distinguished physician's experiments, and * I think it very likely that every patient subject to fits o£ any class has an- epileptogenous zone—that disturbance of the part of the periphery (ento- or cpi-periphery) most especially represented in the discharging lesion may, proToke a fit. t I refer to a paper in ' Brain,' April, 1886, for details of this classification— A Contribution to the Comparative Study of Convulsions.
