will be found of general utility in its various modes of combination, among others as a cement or pigment, supplying the means of preventing the oxidation or deterioration of.

metallic substances, and of precluding the infiltration or percolation of fluids and the absorption of dampness or moisture, preservin g from the injurious effects thereof, and even in some cases guarding againskdestruction by fire, which can be used with great advantage and economy,espeoially in all things that are wanted to be made water-tight in all edifices and constructions'in which stone, wood, timber, earth, or metals are employed, for vessels,-stean1ers, steam and other engines, cordage, various tissues and textures, leather, and in general for materials used in various arts and manufactures.

In order to enable persons skilled in the arts to make and use myinvention', I will proceed to describe the materials employed therein, the mode and process of its composition, and its application. The basis consists in all substances that are combustible and not metallic compounds snch as bitumen, asphaltum, pisasphalt, maltha,mineralcaoutchouc,andproductsobtaine from'the distillationjof fossil coal.

Formdla 1. Of the substancesfabove described as bases, particularlybit'urnen, put any given quantity into'the boiler of a still prepared for the purpose, lute theapparatus,

and heat it in such manner that the essential oil and water embodied in the bitumen shall, during the process of evaporation, be condensed by the cold watercontained in the condenser or cooler of the worm, and at that point when the distillation produces only a few drops of liquid sift the material which re mains in the boiler through metallic cloth or sieves placed over a vessel of suflicient capac ity and containing water enough toprevent adhesion to the bottom or sides. When it has been reduced to a temperature equal to 50 or 60 centigrade--say122. to 140 Fahrenheittake the material out of the water and mold it into lumps.

Formula 2.- To the material prepared as per Formula No. ladd from one to twenty-five per cent. of protoxide of lead or of any other oxide,

and you will obtain a substance more or less .in-

fusible, according to the proportion of oxide which may have been used and fuse together. Formula 3. To'the material prepared as per Formula No. 1 add from one to one hundred per cent. or moreof greasy adipose matter, and

you'will obtaina product more or less fusible in proportion to the greater or less: quantity of adipose matter used.

Formula 4. To tlie'material prepared as per Formula No. 1 add from oneto one hundred per cent. of siccative oil, particularly of linseed, and as much caoutchouc or gum-elastic or m'ucilage, and you will obtain a paint or pigment peculiarly adapted to various textures, tissues,

cloths, paper, .&c., as leaving them perfectly flexible.

Formula 5. To make black varnish of great beauty you must, after heating the bitumen put the bitumen thus prepared over the fire and leave it'so until the essential oil and water contained therein shall be evaporated; then add spirits of wine, or oil of turpentine, or

- others of the same nature until the whole be of proper thicknessfor use. Sealing-waxof great beauty can be obtained by following this the fifth formula, saving the addition of spirits.

of wine and essential oil, which must be omitted. This product, mixed with saw or marble dust or sand, or with the filings or oxides of metals, &c., will answer to makev walls, stat ues, vases, terraces, 8:0.

" In all cases in which it is desired to give this product more or less flexibility there may be added, besides resin and resinous gum, wax,

and especially sulphur, from one to thirty per cent. v

From the essential oil produced by the dis tillafionofbitumenthe re obtainedanaphtha- I therein referred to, of other known substaiices' line in greater quantity and of much purer 0f the same-character, according to the difl'erquality thali'by the distillation of'taror pitch. em; formulas there set forth. 7 i
