Briefly described, it consists in exposing the wool, placed in a hydro-extractor, to the action of bisulphide of carbon; the machine is then made to revolve, and the excess of solvent is expelled, carrying with it the fatty matters; the solvent finds its way into a tank, from which it flows into a still, heated with steam; the carbon disulphide, which boils at a very low temperature, distills over, and is again ready for use, while the residue in the still consists of suint washed from the wool.
Phosphides of iron, zinc, etc., were next introduced, and gave, besides carbon and other impurities, a residue containing a large percentage of phosphorus, which differed from ordinary phosphorus with respect to its insolubility in carbon disulphide, and which resembled the reaction in the case with silicon-eisen rather than that of the boron compound, insomuch that a large quantity of the phosphorus had passed into solution.
Now, when wool moist with bisulphide is heated, it invariably turns yellow. No heat must, therefore, be employed. As already remarked, the solvent is expelled with cold water. The residue, after distillation of the carbon disulphide, is a grayish colored, very viscous oily matter, still retaining a little bisulphide, as may be perceived from the smell.
To remove the last trace of carbon disulphide from the wool in the hydro-extractor, cold water is admitted, and when the wool is soaked, the machine again revolves. On expulsion of the water, the wool is ready for washing in the ordinary machines, but with cold water only instead of hot soapsuds. The distinguishing features of Mr.
We were entitled to expect this, judging by the Spider's general immunity. But here is something that wholly alters the result. I put the leg to soak for a quarter of an hour in disulphide of carbon, the best solvent of fatty matters. I wash it carefully with a brush dipped in the same fluid.
It is a curious fact that, although wool soaks remarkably easily with carbon disulphide, and at once becomes wet, cold water expels and replaces almost all that liquid. This operation takes about twenty minutes, and at one operation about 11/2 cwt. of raw wool may be treated.
It has not the composition of ordinary suint, inasmuch as it contains no carbonate of potash, and indeed little mineral matter of any kind. A sample which I analyzed lost in drying 36.2 per cent., the loss consisting of water and carbon disulphide. It gave a residue on ignition amounting only to 1.6 per cent. of the original fatty matter, or 2.5 per cent. of the dried fat.
Why don't you go out and get it, take it off the scabs the way I do; that in September Feinberg had to make Reese leave the speaker's stand in Everett because he was talking on matters harmful to industrial union propaganda; that on November 4th the witness went to the place where Feinberg was employed and left a suit of clothes to be pressed, saying to Feinberg, after he had ascertained that Feinberg was thinking of going to Everett on the following day, "mark the bill 'paid' so I will have a receipt if you don't come back;" that on August 16th, the day before the big dock fire in Seattle, Reese went to the down-town office of the same dye works in which Walker C. Smith was manager and in charge of the purchase of chemicals and tried to get Smith to purchase for him some carbon disulphide to be used in connection with phosphorus; that in the month of November in the Labor Temple, in the presence of Sam Sadler, Reese had said to Albert Brilliant that if the longshoremen had any guts they would go out with guns and clean up the scabs on the waterfront; and that Reese tried to get other men to co-operate with him in a scheme to capture a Government boat lying in the Sound during the progress of the longshoremen's strike."
From its gravity it sinks, forming a layer below the water; it is then separated and recovered by distillation, and may be used in subsequent operations. The point in which this process differs from the old and unsuccessful ones formerly tried, is in the expulsion of the carbon disulphide. It was imagined that it was necessary to expel it by means of heat or steam.
Did I guess aright when I judged that it was a fatty substance that preserved the Epeira from the snares of her sticky Catherine-wheel? The action of the carbon disulphide seems to say yes. Besides, there is no reason why a substance of this kind, which plays so frequent a part in animal economy, should not coat the Spider very slightly by the mere act of perspiration.
