devoted by this true naturalist and gentleman to naming the 

 insects which on behalf of the Union I have from time to time 

 forwarded to him. Soon after this communication I received a 

 box of insects with the intimation of Dr. Vollenhoven's decease. 

 I was not altogether unprepared for the sad news, as he had 

 in one of his letters remarked in his quaint English, 'Do not be 

 surprised if you should obtain a .long ensueance [interval] of 

 silence. I have been indisposed now for some time, and I fear 

 results which will compel for me a cessation of our pleasant letter- 

 talk. I send to you returned the case of insects, named to the 

 best of my poor endeavours.' Dr. Vollenhoven, eminent and 

 distinguished as he was, was not too clever to assist beginners, as 

 witness the following extract from one of his epistles: 'You need 

 never to apologise to me. The ladder of nature is enough broad, 

 and high, and strong, to bear the weights of all those who desire 



to cUmb.'— S. D. B.
