![have approached this question from both sides. Four years ago, I believed implicitly in Brown-Sequard’s theory of immediate decussation of the sensory impulses, and with an unfortunate result, as the following case will show, reported fully in ‘ Brain,’ 1887.'^ Fig. 2. The case was oue of tumour beginning in the 5th left intercostal nerve. A cyst was subsequently formed which pressed upon the left side of the cord causing numb- ness and iveahiess in the left leg, then of the right, but not so marked. When the patient was admitted in Charing Cross Hospital I carefully tested his condition and made the accompanying diagram (fig. 2) to represent the condition of the sensory disturbance. It will be observed that sensibility to different forms of stimulus is at different levels on tlie two sides. It tends to show that pricking, tactile, heat, and cold sensations pass by different paths, hut it also shows anaesthesia and analgesia at a lower level upon the right than the left side (the seat of origin of the tumour). As the tumour increased in size, the right leg became more involved. It is right to remark in connection Avith this case, that I considered it one of tumour pressing upon the spinal cord, and that I advocated operation, but it was urged against my opinion that tliere should have been the more marked sensory disturbance on the side opposite to the tumour.t * “ Myxo-fihroina of tlie Spinal Corel.” BiiUCR and Mott. ‘ Drain,’ Part 38, 1887. t The autopay showed c(;nclusively the fallacy of accc])ting too rigidly any dogma in medicine.](https://iiif.wellcomecollection.org/image/b22297066_0059.jp2/full/800%2C/0/default.jpg)
