PREFACE. xl 
so many journals, magazines and other periodicals entirely unconnected with 
natural history, that we hope their citation will be favorably received. In set- 
tling the weight due to contradictory statements, we have endeavored to avoid 
the influence which is supposed to be connected with the verba magistri; and in 
all cases have freely, and we trust not offensively, expressed our opinions when 
our own observations have been at variance with those of previous writers.
