Mammalian portion of the ^ Zoological Record.^ In the first of 
these chapters the author treats of the means of expression in 
animals, such as the emission of sounds produced by the vocal 
organs or otherwise, the erection of dermal appendages and hairs 
under the emotions of anger and terror ; the drawing back of 
the ears as a preparation for fighting ; the erection of the ears 
and raising the head as a sign of attention. In the fifth chapter 
the special expressions of various animals (dogs, cats, horses, 
ruminants, and monkeys) are discussed (pp. 83-146).
