ABSTRACT OF THE PROCEEDINGS 



OF THE 



ZOOLOGICAL SOCIETY OF LONDON.^ 



June 27th, 1911. 



Frederick Gillett, Esq., Vice-President, 

 in the Chair. 



The Minutes of the last Scientific Meeting were confirmed. 



The Secretary read a Report on the Additions that had been 

 made to the Society's Menagerie during the month of May 

 1911. 



Dr. W. T. Oalman, F.Z.S., exhibited a number of living 

 specimens of the Brine Shrimp [Artemia salina) which had been 

 bred from Tidman's Sea Salt. He remarked that this sea salt, as 

 sold in the shops, was found frequently to contain living eggs 

 of A^'teinia and that it was easy to obtain a supply of living 

 specimens. An 8 per cent, solution, allowed to stand for a few 

 days, produced a swarm of larvae, and these could be fed on the 

 strained juice of green leaves and raised to maturity. 



Mr. J. Lewis Bonhote, M.A., F.Z.S., exhibited a pair of 

 Egyptian Desert- Mice (Meriones crassus) which showed a darker 

 and more rufous colour than normal examples. This coloration 

 had been artificially produced by keeping the animals in a moist 

 atmosphere at 80° Fahr. They were fii'st exposed to these con- 

 ditions on the 7th of April and a month later were conspicviously 

 darker ; after that the darkening process still continued, but more 

 slowly, and they appeared for some time previous to being killed
