1923- No. 16. THE NEL'ROI.OGICAI. ASPECT OF LEPROSY. 33 



The doubtful hypoalgesia in the right cheek, as indicated in Fig. 23, 

 developed in the course of 4 months into a marked hypoalgetic and hypo- 

 aesthetic area (cf. Fig. 23 a). 



Corresponding to this one can feel the nervus auricularis magnus 

 greatly thickened [cpr. fig. 23, a.] 



At the lower end of this nerve a nodule is felt. This feels like a 

 slightly enlarged lymphatic gland, and would no doubt have been taken for 

 such, had it not been in continuation with the rest of the palpable, thickened, 

 great auricular nerve. Both ulnar and peroneal nerves are considerably 

 thickened. 



Case No. j<S. J. A. (Fig. 2j — 2 6. J 

 Sensor}- chart. Same significance of shading as in previous figures. 

 Pronounced hyperaesthesia for deep pressure in all four limbs. 

 Farradic current applied to left infraoral region elicits great pain 

 localised to the corresponding teeth, but no sensation in the skin. 



Cose A'o. JÇ. K. B. (Fig. 27 — 2S.) 



Sensor}' chart (also maculae indicated). 



This case presents a distinct dissociation between the sensation of 

 heat and cold over the upper part of the trunk (both anterior and posterior 

 aspect). Deep sensation exceedingly good. 



Case No. 60. L. S. Woman aged 65 years. (Fig. 29 — jo.) 

 Early case. First signs of illness in December 191 7. First examina- 

 tion 25 September 1918. 



Sensory chart on first examination. 



All superficial qualities of sensation are equally affected. 



Case No. 61. O. R. Man aged 70 years. (Fig. ji — J2.) 

 Probably quite an old case, but not diagnosed as leprosy till the time 



of examination at which this sensory chart was made out. 



Severe wasting of intrinsic muscles of both hands. All qualities of 



superficial sensation affected to approximatively the same extent. 



Case No. 62. T. E. Man aged 66 years. (Fig. jj — J4.) 

 Mixed form ; typical nodules in the forehead — nodules and maculae on 

 trunk and limbs. 



He maintains that he did not fall ill until a year ago, when he himself 

 noticed sensory loss in left knee and foot. 



The maculae and nodules are indicated on this, as on the previous 

 charts. Both in the maculae and in the shaded areas the loss of sensation 

 in this case had the following character: Profound loss of tactile sensation 

 and temperature sensation; but very litde superficial hypoalgesia.
