ON THE SENSORY DISTURBANCES, OR AESTHETIC 

 PHENOMENA, OCCURRING AT, AND AROUND, THE 

 POINTS OF EXIT OF THE CEREBRO-SPINAL LYMPH, 

 ANTECEDENT TO, AND DURING, EXCRETION. 



THAT the character of the disturbances, or feelings, or 

 sensations, is determined by their locale we have long 

 observed, and, accordingly, have now become satisfied 

 that the painful feelings and itching sensations experienced 

 at times more or less over the whole sensory surfaces 

 of the body, are most largely situated at the points of 

 exit of the cerebro-spinal lymph from its containing 

 vasculature, viz. from the individual sweat glands of 

 the skin generally, the axillary sweat glands and inter- 

 digital surfaces in particular, along with the coccygeal 

 gland duct vasculature, the Schneiderian mucosa, and the 

 tonsillo-glossal mucosa. 



Obstructed exit of the cerebro-spinal lymph, loaded 

 with, it may be, toxic, and, it must certainly be with effete, 

 matter, gives rise to sensory disturbance at the points of 

 obstructed exit, in degree proportionate, we may conceive, 

 indeed, believe, to the amount of stasis and intensity of 

 toxicity of the lymph in process of excretion, and hence 

 may vary, from the slightest feeling of itching, to the most 

 intense feeling of smarting, or acute pain. Thus local, or 

 general, disturbance may be felt as prurigo at the cutaneous 

 exits, annoying itching in one or both axillae, and slight or 

 exasperating irritation at, and around, the anus, while slight, 

 or severe, sneezing may characterise involvement of the 

 olfactory exits, and more or less severe pain may be the
