110 THE MICROSCOPE. July 



paj'te eels have grown fat by feeding on paste. For an amateur 

 microscopist, the paste eels are preferable as they are larger and 

 more readily examined with low powers. To obtain and keep 

 a supply of paste eels boil a little flower and water to the con- 

 sistency of the paste used by bookbinders and shoemakers. 



It is then best to plant some eels in the paste either by pour- 

 ing in some vinegar known to contain them or by jidding a lit- 

 tle paste in which they already swarm. Leave the vessel con- 

 taining them open to the air and to prevent hardening beat it 

 well together whenever it tends that way. To preserve them all 

 the year, put a little water or vinegar to them if the paste grows 

 dry, or supply other paste. Their continual motion will pre- 

 vent any mouldiness of the paste. A one inch objective is suf- 

 ficient to show them nicely. 



CORRESPONDENCE. 



To Begin With. — Get an instrument by any good maker and 

 by all means let it have a rack-and-pinion coarse adjustment. 

 I have known many to begin without one and never knew one 

 to be contented without it. Get a one inch objective. It is all 

 you want. A 1-6 inch objective would be practically useless to 

 to you. I have given lessons to beginners for years and this is 

 the outcome. — Ajax. 



RECENT PUBLICATIONS. 



The Journal of Marine Zoology and Microscopy. Vol. 1, No. 1 

 Nov. 1893. 



This is a biological quarterly dealing with the fauna of British 

 seas ; and contains many interesting facts and accurate descrip- 

 tions, in plain wording and accompanied by original illustrations. 

 Personal observations upon the habits of marine animals, to- 

 gether with notes and short articles upon the numberless pro- 

 blems of shore and ocean life, form leading features. The en- 

 deavour is to avoid the technical language too frequently met 

 with in Zoological writings, as well as to keep the pages free 

 from trivialities and thread-bare expositions of text book matter. 



The Microscopical section consist of "Studies" which deal in 

 pleasant but exact manner with the anatomy, life-history and
