sensory loss might well be due to a lesion in the left posterior grey horn 

 in the mid-dorsal region (D 6 — 8). It is curious, however, that this area 

 of sensory loss could not be found to continue in the lateral and anterior 

 aspects of the trunk. 



Case No. 4. K.P. (Fig. 17-18.) 



Chart of sensory loss. 



In this case the loss of tactile sensation in the lower limbs is much 

 more extensive than that of pain and temperature. 



Over the tip of the right thumb the patient can distinguish between 

 the sharp and the blunt end of a needle, when some pressure is brought 

 to bear. She personally considers the tactile sensation to be perfect in 

 this finger; but it is found that only such tactile stimuli are felt as are 

 combined with a pressure, sufficient to cause an indentation of the surface. 



Case No. 6. G. O. (Fig. ig — 20.) 



Chart of sensory loss. 



In the upper limbs there is a pronounced dissociation between the 

 sensation of pain, which is nearly intact, and tactile and thermic sensation, 

 which are both profoundly aff'ected. On the other hand, the sensation of 

 temperature has remained intact at the back of both thighs, while the tac- 

 tile sensation here is profoundly, and the sensation of pain slightly, affected. 



In both plantae there is a considerable over-reaction to painful stimuli 

 — and only slight tactile hypoaesthesia. 



In both lower limbs a marked hyperaesthesia to deep pressure is lound. 



Case No. 7. K. V. (Fig. 21—22.) 

 Chart of maculae & sensory loss. 



It will be seen that in one of the maculae at the back no sensory loss 

 could be found — in the centre of the other: pronounced .thermoanaesthesia 

 and slight tactile hypoaesthesia, but no hypoalgesia obtained. 



At the back of the right thigh marked tactile anaesthesia, slight hypo- 

 algesia, but no loss of temperature sensation. 



In both plantae there is a distinct overaction to painful stimuli. 



Marked hyperaesthesia to deep pressure in the upper limbs.
