Soak the gelatine in the water and melt with heat. Rub the 
arrowroot into a cream with the water, add to the gelatine 
solution, and boil 10 minutes, with constant stirring. Allow 
to cool, add add: 
Methyl alcohol 125 ccm 5/02: 
Phenol 1.3 ccm 25 min. 
StarcH Paste.—This will not keep longer than a week: 
Pure starch 100 g 1 oz. 
Benzoic acid Ra Ve 6 er. 
(Or salicylic acid) 2.5/2 15 gr. 
Water 1200 cem 12 oz. 
Rub the starch and the acids into a very stiff paste with a 
little water ; it should be so stiff that it is difficult to stir. Add 
the rest of the water boiling, and stir well, when a clear 
smooth paste should be formed. If it is not quite clear, boil 
for a few minutes. Allow to get quite cold, and take off 
the skin that forms on the surface. Somewhat increased 
keeping power is obtained by the addition of formaldehyde, 
1.2ccm (6 min.), which should be added when the paste is 
cold. Wheat or preferably rice starch should be used.
