350 On Tic Douloureux. 



about the facial nerves and muscles, analogous to Tic ; and 

 great irritation from inflamed membranes of some cavity in 

 the upper jaw has also occasioned them. I knew a person 

 who suffered six months from such an attack, and for whom a 

 physician prescribed, in the course of that period, some pounds 

 of carbonate of iron. Symptoms then ensued, for which a 

 course of sarsaparilla was ordered, but it was of no avail. 

 Mercurials were then given, with manifest mischief. The ex- 

 traction of the second grinder effected a permanent cure ; its 

 roots were connected with a cavity of fetid discharge, which 

 had no sooner vent, than all the symptoms disappeared. 



Without exceeding the limits which I have set myself, I 

 cannot proceed further in these remarks ; but I hope enough 

 has been said to quiet the apprehensions of some invalids who 

 suffer themselves to be exceedingly alarmed at the name given 

 to their complaint, and to be dosed with large quantities of 

 useless medicines, which rather aggravate than relieve it. In 

 many of these cases, the less that is done the better ; in all of 

 them, careful reference must be had to the real exciting cause ; 

 and, in addition to the other circumstances adverted to, a strict, 

 attention to diet must be enforced, and more than ordinary 

 watchfulness exerted over the state of the stomach and 

 bowels : plain roast and boiled, and no grease or piecrust in 

 the former ; and for the latter, an occasional blue pill and a 

 tea spoonful of Epsom salt.

Remarks on some Quadrupeds supposed by Naturalists to be 

 extinct. By John Ranking, Esq. 



There is not any part of the creation more interesting to 

 mankind than the gigantic classes of quadrupeds. In them, 

 we are able to contemplate the power of the Creator of all 

 things, in one of the most magnificent exercises of his will. 

 Such, however, is the limit to this kind of knowledge, that there 

 is probably not any one class, even of the largest quadru- 

 peds, all the species of which are, or possibly ever can be, 

 known to the student of natural history, More than half of
