Ball, Animal and Solution Scale, well adapted for weighing 
guinea-pigs. It will weigh liquids with an accuracy that can- 
not be approached by ordinary methods. The Scale is pro- 
vided with an extra balancing beam by which an empty bottle 
or container is quickly balanced, by simply sliding the balance 
weight along until a correct balance is secured ; the new ball 
system is used in place of the weights ; this is a great im- 
provement over the old method. The scale weighs from lo 
gram to i6 kilos, with the utmost accuracy and perfection. 
Capacity, i6 kilo. Price $20 00
