Plasma. 
Two samples,—one recently prepared, the other made in December, 1865, and 
exhibited for the purpose of showing that, although kept in an ordinary covered 
pot, it had retained its beauty and consistence well. The formula employed was 
the one originally suggested by the exhibitor in February, 1858, viz.:—Starch 70 
grains, pure glycerine 1 fl. oz., mix cold, and heat to 240° F., constantly stirring.

Thirty specimens of medicated lozenges. 
Patented perforated liquorice. 
Of all the various preparations, the stick liquorice is by far the greatest favourite, 
but some difficulty is always experienced in cutting it up for use, so much so, that 
other kinds, inferior in quality, but more convenient in form, are occasionally preferred 
before it. Desirous of obviatiug this drawback to its use, the patentees have at last 
succeeded in originating a method of manufacture, by which the liquorice is still 
made in the same form, and yet can be reduced at pleasure, withoutlo ss of time or 
material, to convenient-sized fragments ready for use.
