In this way they effect the decomposition of the tartrate, from which they must necessarily obtain the carbon of their food without which they cannot exist, while the nitrogen is furnished by the ammonia of the ammoniacal salt, the mineral principles by the phosphate of potassium and magnesium, and the sulphur by the sulphate of ammonia.
And I have not yet been able to meet with any advocate of Abiogenesis who seriously maintains that the atoms of sugar, tartrate of ammonia, yeast-ash, and water, under no influence but that of free access of air and the ordinary temperature, re-arrange themselves and give rise to the protoplasm of Bacterium.
Give daily a ball of tartrate of iron, digitalis, ginger, and a grain of calomel. 22'd'. Much thinner, the belly very considerably diminished: a slight fluctuation is still to be perceived. Continue medicine, with a half-grain only of calomel.
Moreover, it was noticeable that the masses of these latter rested on tartrate not yet dissolved, whilst the granular clusters of the others rested directly on the glass, at the bottom of the flask, as if, having decomposed the tartrate, the only carbonaceous food at their disposal, they had then died on the spot where we captured them, from inability to escape, precisely in consequence of that state of entanglement which they combined to form, during the period of their active development.
Basil Valentine, the German Benedictine monk and alchemist, who wrote a book which he quaintly termed The Triumphant Wagon, in praise of the healing properties of antimony, actually thought that he had discovered the Elixir of Life in tartrate of antimony, more generally known as tartar emetic.
The electro deposition of zinc has been subject to many patents, and the efforts to introduce it have been lamentable in both a mechanical and financial sense. Most authorities recommend a current density of 18 or 20 ampères per square foot of cathode surface, and aqueous solutions of zinc sulphate, acetate or chloride, ammonia, chloride or tartrate, as being the most suitable for deposition.
Be this as it may, in a subsequent experiment we shall find the possibility removed of any aeration taking place in this way, however infinitesimal, so that no doubts may linger on this subject. The following days the organisms multiplied, the deposit of tartrate gradually disappeared, and a sensible ferment action was manifest on the surface, and throughout the bulk of the liquid.
Or, the following will be found quite satisfactory; nitrate of potash, two drachms; camphor, half a drachm; tartrate of antimony, half a drachm; mix, and give in a little gruel, night and morning. Or, the following: Glauber-salts, four ounces; water, one pint; give twice a day. A gill of cold-drawn castor-oil, added to the above, would be beneficial. Continue until the bowels are freely opened.
This separation presents considerable difficulty, because the metal is not precipitated as a compact mass on the platinum. The bismuth is always obtained in the same form, no matter whether it is precipitated from an acid solution, or from the double ammonium oxalate, or, finally, from a solution to which potassium tartrate has been added.
It should be noted that the acid oxalate and the acid tartrate each contain one hydrogen atom replaceable by a base, while the tetroxalate contains three such atoms and the oxalic acid two. Soda ash is crude sodium carbonate.
