Quarterly Journal of Microscopical 



Science. 



The SUBSCRIPTION is £2 for the Volume of Foui- Numbers; 

 for this sum {prepaid) the Journal is sent Post Free to any part 

 of the world. 



BACK NUMBERS of the Journal, which remain in print, are 

 now sold at an uniform price of 10/- net. 



The issue of Supplement Numbers being found iuconveuient, 

 and there being often in the Editor's hands an accumulation of 

 valuable material, it has been decided to publish this Journal at 

 such intervals as may seem desirable, rather than delay the appear- 

 ance of Memoirs for a regular quarterly publication. 



The title remains unaltered, though more than Four Numbers 

 may be published in the course of a year. 



Each Number is sold at 10/- net, and Four Numbers make 

 up a Volume.
