This work is continued in the same clear style as that in 
which it was commenced (cf. Zool. Rec. vi. p. 30). The four 
parts under consideration refer principally to the muscles, the 
dissertation on which is introduced by a good account of the 
literature relating to these structures. The plates are carefully 
drawn, and those illustrating the muscles, being partially 
coloured, are especially instructive. [See also Anatomy.^^]
