h; and yet these viscid lumps of
bile may afterwards dissolve, and not be visible among the feces.

In two instances I have seen from thirty to fifty gall-stones voided after
taking an oil vomit as below. They were about the size of peas, and
distinguishable when dry by their being inflammable like bad wax, when put
into the flame of a candle. For other causes of jaundice, see Class I. 2.

M. M. Diluents, daily warm bathing. Ether mixed with yolk of egg and water.
Unboiled acrid vegetables, as lettice, cabbage, mustard, and cresses. When
in violent pain, four ounces of oil of olives, or of almonds, should be
swallowed; and as much more in a quarter of an hour, whether it stays or
not. The patient should lie on the circumference of a large barrel, first
on one side, and then on the other. Electric shocks through the gall-duct.
Factitious Selter's water made by dissolving one dram of Sal Soda in a pint
of water; to half a pint of which made luke-warm add ten drops of marine
acid; to be drank as soon as mixed, twice a day for some months. Opium must
be used to quiet the pain, if the oil does not succeed, as two grains, and
another grain in half an hour if necessary. See Class IV. 2. 2. 4.

9. _Calculus renis._ Stone of the kidney. The pain in the loins and along
the course of the ureter from a stone is attended with retraction of the
testicle in men, and numbness on the inside of the thigh in women. It is
distinguished from the lumbago or sciatica, as these latter are seldom
attended with vomiting, and have pain on the outside of the thigh,
sometimes quite down to the ankle or heel. See Herpes and Nephritis.

Where the absorption of the thinner parts of the secretion takes place too
hastily in the kidnies, the hardened mucus, and consequent calculous
concretions, sometimes totally stop up the tubuli uriniferi; and no urine
is secreted. Of this many die, who have drank much vinous spirit, and some
of them recover by voiding a quantity of white mucus, like chalk and water;
and others by voiding a great quantity of sand, or small calculi. This
hardened mucus frequently becomes the nucleus of a stone in the bladder.
The salts of the urine, called microcosmic salt, are often mistaken for
gravel, but are distinguishable both by their angles of crystallization,
their adhesion to the sides or bottom of the pot, and by their not being
formed till the urine cools. Whereas the particles of gravel are generally
without angles
