PREFACE. XIU 



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.
