following drench should be given three times a day, for seven or eight 

 days if it is necessary and appears to benefit: Tincture of the per- 

 chloride of iron, 1 ounce; tincture of gentian, 2 ounces; water, 1 pint. 

 Also give 1 dram of iodide of potassium dissolved in the drinking-water 

 an hour before feeding, every night and morning for a week or two. 



Hydro-thorax is sometimes difficult to overcome by means of the use 

 of medicines alone, when an operation called paracentesis tlioracis is 

 performed. In plain language this means tapping the chest to allow an 

 escape for the accumulated fluid. The operation is performed with 

 a combined instrument called the trocar and canula. The punctnre is 

 made in the lower part of the chest, in the space between the eighth 

 and ninth ribs. Wounding of the intercostal artery is avoided by in- 

 serting the instrument as near as possible to the anterior edge of the 

 rib. If the operation is of benefit it is only so when performed before 

 the strength is lowered beyond recovery. The operation merely re- 

 ceives a passing notice here, as it is not presumed that the non-profes- 

 sional will attempt it, although it is attended with little danger or diffi- 

 culty in the hands of the expert. 



We have described bronchitis, pneumonia, and pleurisy mainly as 

 they occur as independent diseases, and have treated them in a way 

 that an intelligent person can not possibly do harm. While it is true 

 much more might have been said in regard to the different stages and 

 types of the affections, and also in regard to the treatment of each stage 

 and each particular type, the plan adopted is considered the wisest on 

 account of simplifying as much as possible a subject of which the reader 

 is supposed to know very little, if anything. 



A few words will now be devoted to these affections as they occur, 

 when two or more exist at the same time and in the same animal. 



PLEURO-PNEUMONIA. 



The disease is so called when the animal is affected with pleurisy and 

 pneumonia combined, which is most frequently the case. At the be- 

 ginning of the attack only one of the affections may be present, but the 

 other soon follows. It has already been stated that the pleura is closely 

 adherent to the lung. The pleura on this account is frequently more or 

 less affected by the spreading of the inflammation from the lung tissue. 

 There is a combination of the symptoms of both diseases, but to the or- 

 dinary observer the symptoms of pleurisy are the most obvious. The 

 course of treatment to be pursued differs in no manner from that given 

 for the affections when they occur independently. The symptoms will 

 be your guide as to the advisability of giving oil and laudanum for the 

 pain if the pleurisy is very severe. Do not resort to it unless it is nec- 

 essary to allay the pain. 



BRONCHO-PLEURO-PNEUMONIA. 



This is the term or terms applied when bronchitis, pleurisy, and pneu- 

 monia all exist at once. This is by no means a common occurrence.
