Proportion Study of a Dog's Muzzle
A red-chalk dog's head with lettered construction lines and proportional equalities
A finely drawn red-chalk study of a dog's muzzle in profile is overlaid with straight construction lines and letter labels used to compare its proportions. The accompanying note sets out the measured relationships: that a b c are equal, that S r a c are equal, and that o r and t f l are similar. The lettered intervals f-l, b-a and r-c mark the segments being weighed against one another.

Muzzle of a dog in profile
The caption names the drawing 'muzzle of a dog.' In red chalk the head is shown in profile, the snout and open jaw modelled with soft fur, and ruled construction lines laid across it to fix its proportions.
Lettered proportional relationships
The note pairs the lettered points along the muzzle and records their proportions: a b c are equal, S r a c are equal, o r are similar, and t f l are similar. The segments f-l, b-a and r-c name the intervals being compared.
