' Obsej'vations on this Case by Dr. Thornton. 



I. Chlorotic consumption, even oftener than any other, 

 proves fatal from the pernicious treatment of this disease, as 

 considering it a true consumption, and lowering the patient, 

 It arises from a defective oxygenation of the blood. 



II. Steel gives the blood more power to abstract oxy- 

 gen," and form of it one of its component parts : hence the 

 benefit of this remedy. Tonics do the same, but in a less 

 degree. 



ill. That the superoxygenated marine acid gas imparts 

 oxygen to the blood, or animal fibre, is shown by Girtan- 

 ner (vide Beddoes* translation), who thinks that no sub- 

 stance imparts more of this principle; and hence, when 

 concentrated, as in the superoxygenated muriatic acid, its 

 most powerful effects ; when having acted on the animal 

 fibre, it is no longer superoxygenated : hence in the form 

 of gas, probably, the oxygen is in a similar manner, 

 though in a less degree, imparted to the blood or animal 

 fibre. 



IV. As this air may require more caution than in acci- 

 dental admixture with common air in an apartment, much 

 good may hereafter be derived from it under a prudent ad- 

 ministration. Sed ars longa, vita brevis, as Hippocrates 

 observes, and the strong prejudices against aerial remedies 

 still exist. 



XIII. Description of Mr. William Bowler's improved 

 Churn *. 



Jt 1 or this improvement, thirty guineas were voted to the 

 inventor, by the Society for the Encouragement of Arts, 

 Manufactures, and Commerce, which has one of the churns 

 reserved in its repository for the inspection of the public. 



The churn itself is of the barrel kind, being a cylinder 

 eighteen inches diameter and nine inches wide, the sides 

 wood, and the rim tin plate, having two openings; the 

 one, eight inches and a half long, by four inches wide, 

 through which the cream is put into the churn, and the 

 hand introduced for cleaning it ; the other, a short pipe one 

 inch diameter, by which the butter-milk runs out of the 

 churn when the operation is finished. The first of these
