LEA ^as formerly kept in the shops, atKl is still occasionally employed for drawing blisters, and exciting salivation. — The leaves of lead- wort, according to Beghstein, are vulnerary, and may be advan- tageously applied to the back of horses injured by the pressure of the saddle, or for healing other sores. LEAF, a distemper incident to lambs, when about a week or fort- night old. — It has received this ap- pellation ; as the creatures feed on oak and hawthorn leaves, which cause them to foam at the mouth, reel and stagger, so that the;,' sud- denly drop down and expire. Although we arc not acquainted with any certain remedy for this malady, yet we believe it may be cured in its early stages, by giving the young animals thus injured, a mixture of equal parts of oil and vinegar, in frequent small draughts poured inlo the throat, and at the same time administering clysters composed of similar ingredients. LEATHER, the skins of various quadrupeds dressed in a particular manner, for "the use of manufac- tures. — See CoREYiKG and Tann- ing. Dyeing- of Leather: DitTerent colours may be imparted to leather, according to the uses for which it is designed. Thus, a blue is given by immersing the piece for the space of twenty-four hours in urine and indigo, after which it is boiled in alum ; or this colom" may be communicated by tempering the indigo with red wine, and steeping the skins in the mixture. A red colour is obtained, by first washing the skins, which are then soaked for t[)e space of two hours in galls, wrung out, and immersed in a h(j^uor prepared by a solution Lea [79 of privet ( Ligustrnvi vulgare, L.), alum, and verdigrease in water 5 when they are steeped in a dT6 made of Brazil-wood boil':"d with ley. — In order to communicate a purple, the skins are wetted with a solution of Roman alum in v>'arm water ; and when dry, they are rubbed by the hand with a decoc- tion of logwood in cold water. Leather acquires a light-green tinge, by applying to it sap-greed diluted with boiled alum- water :— 4 a dar}-green cast is Communicated by means of steel-filings and sai ammoniac, steeped in urine for a considerable time, and well rubbed into the skin, w hich is then to be dried in the shade. A yellow colour is given, bv anointing the skin with a decbtiion of aloes and linsee'd-oil, previously strained ; or, by injmersing it id a solution of dyer's-greei) wded'. Lastly, if fustic-berries be boiled in alum- water, and t'le skins dipj>- cd in the liquoi', they will acquire a lighl-orange shade ; but, if ^ deejier hue be required, it will be necessary to substituie turmeric for the berries. — For an account of th6 preparation of red, yellow, or other Turha/ leather, we refer the reader to the article Mcrocco. Leather being an article of ex- tensive utility, especially for shoes and boots, various processes have b 'cn contrived for rendering it ivater - proof : we have already stated a simple method to this ef- fect (vol. i. article Boot) 5 andj that our rcalcrs may become fully accjuaiiited with this interesting branch of cc(;nomy, we shall nov give a supplementary account cf the dilFereiit preparations, &c. in- vented Jbr that purpose.
