40 Dr. Venables on the Cystic Oxide, &c. 



The bowels should be kept moderately open, and the diges- 

 tive functions be properly attended to and regulated. The due 

 action of the skin should be promoted by an occasional resort 

 to the warm bath, and the exhibition of mild diaphoretics. 



I know of nothing superior to small doses of the sulphate of 

 morphia, combined with acatic extract of colchicum, ipeca- 

 cuanha, and hyoscyamus, hop, &c. These means I have 

 found valuable in analogous conditions of the urine, and can 

 recommend them from experience by no means confined. 

 Such means steadily persevered in, I am inclined to hope, 

 may prove highly beneficial; and in cases not marked by 

 unusual severity, may possibly suspend the advance of the 

 disease, or at all events, defer to a distant period the fatal 

 termination.

 oxide,'' suggested by Dr. Marcet; yet, as neither he nor 

 Dr. Prout, nor any of those who have preceded me upon this 

 affection, have ventured to alter the name given to it by its 

 discoverer, I have not deemed it prudent to attempt any inno- 

 vation, and have, therefore, in this paper adopted the name 

 originally bestowed upon it by the late Dr. Wollaston. 



On the Coal-field of Sutherland, By J. Mac CuLLOcn^ M.D., 

 F.R.S., &c. &c. 



Although the " coal-field" of Sutherland was known to 

 Mr. Williams, and has more recently been examined in a 

 professional manner by an experienced surveyor, no account 

 of it has yet been laid before the public. The singularity of 

 its geographical position, nevertheless, and the peculiarity of 

 its geological connexions, render it an object of great interest 

 to a geologist ; and they have induced me to draw up the fol- 

 lowing account. The circumstances of this Journal must be 

 an excuse for not adding the map which belongs to it.
