OIL OF PINE TEREBENE TERPENE-HYDRATE 607 



oil, soft soap, or ammonia liniment. Convenient stimulant 

 dressings are made with equal quantities of oil of turpentine, 

 bland oil, and soft soap, or two to three ounces of oil of 

 turpentine are added to a pint of soap liniment. As a 

 stimulant for rheumatism, equal parts of oil of turpentine 

 and laudanum are mixed with two or three parts of linseed 

 oil or soft soap. For dogs, an active embrocation is prepared 

 with an ounce each of oil of turpentine and medicinal 

 ammonia, and six to ten ounces of olive oil. 



OIL OF SCOTCH FIR (oleum pini sylvestris) is prepared 

 by distilling the fresh leaves of the Scotch fir or Pinus 

 sylvestris. It has most of the properties, and is applied 

 for many of the uses of oil of turpentine. 



TEREBENE being less acrid than oil of turpentine, and less 

 liable to act on the kidneys, is sometimes substituted for 

 it, especially as an internal stimulant and antiseptic in 

 excessive mucous discharges, and for relieving flatulence. 

 Externally, it is applied as a stimulant, antiseptic, and 

 deodoriser. 



OIL OF PlNE, oleum pini (pinol or pumuline), the oil dis- 

 tilled from the fresh leaves of Pinus Pumilio, is used as an 

 inhalation in bronchial catarrh and in laryngitis. 



TERPENE HYDRATE (C 10 H 26 2HO), prepared by passing a 

 current of air through a mixture of four parts oil of tur- 

 pentine, one part nitric acid, and three parts rectified spirit. 

 It is crystalline, has a slight agreeable balsamic odour and 

 taste ; is soluble in 220 parts of cold water, twenty-two 

 parts of warm water, and very soluble in alcohol, ether, 

 turpentine, and oils. Its general actions resemble those of 

 oil of turpentine. One or two drachms may be swallowed 

 by small dogs without causing gastric derangement ; two 

 to three drachms quickly produce intoxication with rest- 

 lessness, uncertain gait, impaired vision, and dreaming, 

 followed in a few hours by sound sleep. It has been pre- 

 scribed in bronchitis, especially in dogs, to stimulate secretion 

 in the earlier stages, and in the later chronic stages to liquefy 

 and so get rid of excessive discharges. The doses for horses 

 or cattle are grs. xxx. to 3ij- ; f r dogs and cats, grs. v. to 

 grs. xxx., repeated two or three times daily, and given with 

 alcohol, glycerin, or syrup, in drench or in the patient's food.
