ARTIFICIAL CRYSTALLINE CARLSBAD SALTS. 



Sulphate of potassium, 2; chloride of sodiuiu, 

 18; sodium carbonate crystals, 61; sulphate of 

 sodium crystals, 88; distilled water, 50 parts. 

 Dissolve the sulphate of potash and the chloride 

 of sodium in the water, and add this solution to 

 the other two salts, previously melted in their 

 water of crystallization. Evaporate to 180 parts, 

 cool, and stir to prevent the formation of large 

 crystals, without, however, allowing them to be 

 reduced to powder. Dry in the air, moistening 

 occasionally with a little of the mother liquor. 

 By dissolving 8 grammes of this crystalline salt 

 in a litre of water, artificial Carlsbad Sprudel 

 water is obtained. — Bullet. Commercial sl^xv.,

ARTIFICIAL KISSINGEN SALTS. 



Chloride of potassium, 17; sodium chloride, 357; 

 anhydrous sulphate of magnesium, 59; bicar- 

 bonate of sodium, 107 parts. Dry separately and 

 rub together. Seven grammes dissolved in a 

 litre of water forms artificial Kissingen water. — 

 Bull. Comm. xxiv, 323. 



A NEW STYPTIC 



Accidentally discovered by Dr. Roswell Park, 

 is formed by the combination of antipyrine and 

 tannic acid in almost any proportion. The re- 

 sulting compound is sticky, and may be applied 

 oa a sponge. — Med. Council. 



FORMALDEHYDE IN OINTMENTS. 

 F. Lester finds that formaldehyde makes an 

 excellent preservative for ointments. One pound 

 of lard was heated j ust sufficiently to soften well 

 and two drachms of formaldehyde was then 

 stirred thoroughly into it. After cooling, the 

 lard was placed on a shelf where it was exposed 

 to summer temperature, but after keeping for 

 some time it did not show the slightest trace of 

 rancidity, appearing as fresh as when first treat- 

 ed; Ointment of zinc oxide similiarly prepared 

 gave equally satisfactory results, whereas ben- 

 zoated lard carefully prepared at the same time 

 and kept under identical conditions soon went 

 distinctly rancid. The objection that formalde- 

 hyde is a strong reducing agent is met by the 

 suggestion that this need not be considered, 

 having regard to the small proportion neces- 

 sary. — Western Druggist, xviii., 345. 



A REMEDY FOR PILES. 



An ointment composed of equal parts of sub- 

 nitrate of bismuth and castor oil. Keep the 



parts perfectly clean, and apply the ointment 

 well into the rectum. It gives immediate relief 

 and in all recent cases it cures. — Chicago Died.

TOOTH POWDEES. 



The Progress Medical for December 28, 1895, 

 publishes the following formulas which are 

 recommended by M. Metral in the Bulletin 

 General de Therapeutique : 



1. Strontium carbonate, 



Flowers of sulphur, each 225 grains. 



Essence of rose 6 drops. 



2. Strontium carbonate - 90 grains. 



Flowers of sulphur 195 " 



Medicinal soap 55 " 



Essence of rose 6 drops. 



Mixture of gum arabic. 



Glycerine, each, sufficient quantities. 

 The strontium salt, says the writer, assures 

 buccal asepsis by reason of its preservative and 

 antiseptic action. Safranine also gives good re- 

 suits as an antiseptic, and for this reason it 

 should take the place of the ordinary coloring 



M. Metral employs the following : 

 matter in liquid dentifrices. 



Salol 30 grains. 



Tannin 30 " 



Saccharin .-_ 4 " 



Spirit of lavender. 



Spirit of melissa, each 225 " 



Safranine hydrochloride -O.50 " 



Cologne water 2 75 ounces 



Essence of peppermint 12 drops. 



The Therapeutische Wochenschrift is cited as 

 attributing the formula to Thomson : 



I. Prepared chalk 2 ounces 



Pulverized camphor - 150 grains. 



Saccharin 15 " 



VEHICLE FOR CASTOR OIL. 

 A new method of disguising the disagreeable 

 taste of castor oil is reccommended as follows; 

 15 to 20 grammes (say \ fluid ounce) of the oil 

 are mixed with a glassful of milk and heated 

 under constant stirring. In a few moments a 

 perfect emulsion is formed, to which is then add- 

 ed a little syrup of orange flowers, resulting in an 

 active preparation of an agreeable taste. An- 

 other method consists in shaking castor oil with 

 brown-beer in a bottle, or mixing the two in a 

 jar with a rotatory motion. This is said to yield 

 a mixture that is very agreeable to take. — Phar.
