In conclusion I have specially to thank Mr. O. Salvin for the 

 extremely kind way in which he has placed at my disposal a large 

 collection of Mesomyodian birds in spirit. From this I have been 

 able to make out the peculiarity in the distribution of the vessels in 

 the leg ; and from it also I hope to obtain materials for another paper 

 shortly, in which the syrinx of some of the yet little-known forms 

 will be described.
