Of Weights and Measures . 
The Grain weight therefore does not enter into this 
division of the Cologne Mark, but in the division for 
weighing gold and silver it is used, as will be mentioned. 
The other set of weights used commonly in Germany 
is the Nuremburg Medicinal Weight , the integer or 
pound of which is divided precisely the same as the 
apothecaries’ division of the English pound Troy ; that 
is to say, the pound into 12 ounces, the ounce into 8 
drams, the dram into 3 scruples, and the scruple into SO 
grains. Neither the pound nor ounce nor dram of the 
Nuremburg weight are the same as the pound, ounce, 
and quentchen of the Cologne weight, the Nuremburg 
pound being — 100433.5 standard parts — and the ounce 
zz 8368.635 St. Pts. For commerce and common use 
the Nuremburg pound is increased to 16 ounces zz 
133898 St. Pts. 
The Nuremburg medicinal pound of 12 ounces ap- 
pears to be the standard for apothecaries’ weight all over 
Germany, and therefore is probably that which is more 
commonly used by chemists. Hence, when we meet with 
the term pound, ounce, dram, and grains, in German che« 
mical authors, we may generally conclude that it is the 
Nuremburg medicinal weight, unless otherwise specified. 
But the Cologne Mark weight is employed universally 
for assaying gold and silver, and therefore is also of ve- 
ry frequent occurrence. 
The English Troy pound is given by Gren as equal 
to 104688 St. Pts. of the Cologne Mark, whence the 
Nuremburg pound, ounce, dram, scruple or grain zz 
.959266 English Troy pound, ounce, dram, &c. respec- 
tively : or by the following Table.
