Explanation of plates 30-33 



The figures are so freely alluded to in the accompanying text that further explana- 

 tions would perhaps involve unnecessary repetitions. It should be stated, however, 

 that all the figures were drawn with the aid of a camera lucida. Figures 1-26, 28-33, 

 46-4S, and 51-53 were drawn with a Bausch and Lomb ^-inch objective and i-inch 

 ocular; 27, 36, 37, 39, 42, 49, 50, and 54, with a '^-inch objective and 2.inch 

 ocular ; 34, 35, 38, 40, 41, and 43, with a ^-inch objective and ^-inch ocular; and 

 44 and 45, with a %-inch objective and l-inch ocular. THe original drawings have 

 been reduced one half.
