Mr. Shaw on the Facial Noves. 243 



The difference of the degree of sensibility in the two sides 

 corresponds with that found in the experiment on the ass, 



A description of several different kinds of palsy will be given 

 in my next communication, to prove that the changes produced 

 on the human countenance in palsies, depend on the particular 

 system of nerves diseased, and that the two systems are seldom 

 or never affected at the same time. It will also be shewn, that, 

 by exciting the actions regulated by the one system of nerves, 

 the distortion caused by paralysis of the other will disappear. 



By a knowledge of these facts, it may be expected we shall 

 not only be able to form a more correct diagnosis of the nature 

 and seat of palsy than heretofore, but also to estimate the de- 

 gree of danger attending each class of symptoms.

 Editor of the Journal of Science, on the administration of 

 Iodine in Scrofula*. 



When- I published my second Memoir, I already possessed a 

 great number of good observations on what I regard to be the 

 complement of my discovery, that is, the employment of iodine 

 by friction in strumous swellings, and other scrofulous affec- 

 tions. An experience, much extended and varied since, has 

 confirmed me fully in the belief that iodine is the specific of 

 this class of maladies, against which we possessed only second- 

 ary remedies, namely, those which act indirectly, whilst I find 

 that this excites directly and exclusively the lymphatic system, 

 whence we obtain surprising success in the above cases.
