An example of Qattening isshown in Fig. 106. On the other hand,there is sometimes very little narrowingto be discerned. At the compressed partthe cord is usually grey in tint; its consist-ence is lessened in early cases, and in-creased in those of long duration. Thechange in colour and consistence is dueto the inflammation of the substance of thecord which always results from pressure,and may often be traced for some distanceabove and below the compressed there is much compression there isalways much inflammation, but considerablemyelitis may occur when the amount of com-pression is slight.
