 quarter of a century as a lighthouse-keeper, under the 

 Northern Lighthouse Board, Mr Campbell made the fullest 

 use of his ample opportunities of observing the bird-life 

 around his lonely station, whether at the Bell Rock, the 

 Bass Rock, or the Noss Head, Wick. At the Bell Rock he

 entitled The Natural History of the Bell Rock, in which he 

 treats of the seasonal fluctuations in the bird-life round the 

 lantern and in the lower life peopling the surrounding waves 

 and rock-pools. At the Bass he assiduously studied the 

 habits of the Gannet, and made a series of valuable notes, 

 which are incorporated in Mr Gurney's monograph. He 

 also contributed some useful records of insects occurring at 

 the Bass lantern, which are included by Mr Evans in the 

 papers recently published by him in our pages.
