516 MATERIA MEDIC A 



TAR. — Fix Liquida. This is a good remedy for thrushes, 

 and other diseases of the frog. It appears to promote the 

 growth of horn, by gently stimulating the secretory vessels of 

 that part. 



The rotten parts of the frog having been carefully removed ' 

 "with a knife, and the rest well cleansed, the tar is to be melted 

 and poured into the cleft or cavity : a pledget of tow is then to 

 be laid on the part and confined by some proper contrivance. 

 In bad cases, a small proportion of sulphuric acid should be 

 carefully mixed with the tar ; and when a thrush has degenerated 

 into the disease termed canker, a large proportion of the acid 

 should be employed. See Liniments. 



Tar mixed with oil of turpentine and cantharides forms 

 a strong blister. It is sometimes employed as a remedy for 

 cough. 



Tar, when mixed with verdigris or finely powdered blue or 

 white vitriol, forms a good liniment or ointment for canker or 

 thrushes. It may be occasionally employed with alum, and, 

 when mixed with tallow, is an excellent stopping for flat thin 

 soles. In the latter form it makes a good hoof ointment ; and, 

 Avlien rubbed about the coronet and hoof, is said to render the 

 hoof tough. 



TARTAR. — Tartarum. An acid substance, found about 

 the sides and bottoms of casks in which wine is fermented ; when 

 purified, it is termed crystals, or cream, of tartar. Farriers gene- 

 rally employ it in their purging medicines, upon the authority of 

 some old writers, who supposed it to have the property of cor- 

 recting aloes. See Cathartics. 



TARTAR, VITRIOL ATED. See Sulphate of Potash. 



TARTARIZED ANTIMONY. See Emetic Tartar and 

 Antimony. 



TARTRATE OF POTASS. See Soluble Tartar. 



TEREBINTHINA. See Turpentine. 



TIGLII OLEUJ^t. Croton oil, which see. 



TIN. — Stannum. This metal is a good anthelmintic for 

 dogs ; and, though not employed in vetei'inary practice, appears 

 to be worth a trial. I have known great numbers of worms dis- 

 charged from dogs, by giving filings or scrapings of pewter, 

 which is composed principally of tin and lead. The dose about 

 a drachm. See Anthelmintics. 



TINCTURES. — Tincturce. Medical preparations made by 

 infusing or digesting vegetables, &c. either in rectified or proof 

 spirit. Examples : — Compound tincture of benzoin, commonly 

 named Friar's or Traumatic balsam, is made by digesting gum 

 benzoin, aloes, &c. in rectified spirit. Tincture of opium 

 is made by digesting opium in proof spirit. There are also 

 tinctures made with vinegar, such as squill and meadow saffron.
