 the most pleasure; but most of the fresh knowledge 

 I have been able to collect in this department is 

 contained in a larger work Argentine Ornithology 

 written in collaboration with Dr P. L. Sclater. As I 

 have not gone over any of the subjects dealt with 

 in that work, bird-life has not received more than 

 a fair share of attention in the, .present volume."
