loss ; while in this dilemma the British Association for the 

 advancement of Science, held its meeting in Glasgow, 

 when Sir William Jardine proposed, and Mr. Selby 

 seconded, a recommendation that the sum of 50. sterling 

 should be granted for the purpose of assisting to further 

 our knowledge of the British Anoplura. This motion was 

 carried, and the above sum very handsomely placed at my 

 disposal to remove in part the above difficulty.* Lastly, 

 to Dr. Greville, of Edinburgh, I feel deeply indebted for 

 his exertions to forward my views, by procuring me patron- 

 age, in the way of subscribers, which in the early part of 

 my labours stimulated me to proceed. 



" Still let me various Nature scan, 



The world's my home, my brother man, 

 And God is every where.'' PETRIE. 



* The following gentlemen were appointed as Trustees to see the object 

 of the grant carried into effect Sir Wm. Jardine, P. J. Selby, Esq., Wm. 

 Yarrell, Esq., and Dr. Lankester.
