Zur Reduction der Lesungen des Bifilars und der Lloyd’schen Waage dienen die 
Formeln: 
H= 2.0663 — 0.0002257 [(160 — L) — 4.116 (¢ —15)] 
V =4.1017 + 0.0005684 [(Z,—110) + 5.137 (¢, — 15)] 
wobei L und L, die Lesung an der Scala des Bifilars und der Lloyd’schen Waage, ¢ und 
t, die entsprechenden Temperaturen bedeuten.
