solemnly proclaimed. While this is sad, still we have left to 

 cheer us the fact that the forsaken child commenced at once to 

 grow and develop in the most surprising way and to-day stands 

 in physical and intellectual development far ahead of anything 

 of its kind ever known. 



We have seen the lines on the Amphijyleura pellucida, with 

 a one-six objective, but never with a one-fifth. The Gundlach 

 Optical Company are to be congratulated that the first one-fifth 

 to do this comes from their house. 



Mr. Jas. Zentmayer has removed from his old stand to No. 

 201 South Eleventh street. Here he will keep a full line of 

 spectacles and eye-glasses in addition to his regular stock of 

 Microscopes. Mr. Zentmayer has been engaged in his work 

 over thirty years and has made a proud record for business in- 

 tegrity. 



Mr. Woolman gives us a " special outfit" in his new adver-

 pared to meet all demands, it seems, from five to fifteen hundred 



dollars.

Dammar Cement. — Dissolve gum dammar in benzole, and 

 add one-third of gold-size ; it dries very quickly, and is prefer- 

 ably used as a first coat for affixing the cover-glass when glycer- 

 ine is used for mounting. 



Gum, for attaching labels, covering papers, and objects 

 mounted dry (as parts of insects, foraminifera, etc.). Dissolve 

 2 ounces of gum arabic in 2 ounces of water, and add 2 drachms 

 of soaked gelatine (for the solution of which the action of heat 

 is required), 30 drops of glycerine, and a lump of camphor.
