6. On the Hydrates of Monobasic fatty acids.—Grrmavx sug- 
gests the existence of bodies analogous to the glycerins, but in 
which the hydroxyls are united to the same carbon atom. _ These 
bodies he calls carberins. They are produced by hydrating the 
monobasic fatty acids. Thus, fomic acid cH a plus H,O 
OH 
gives CH OH formyl-carberin ; acetic acid CH,.C} oe gives

CH,.C { OH acetyl-carberin. These hydrates are known and have 
been described. Moreover, chloral hydrate is a chlorinated glycol, 
having two hydroxyls united to the same C atom; OCl,--CH, OH

The carberin ethers, as CH? OH or CH,.C on are

7. On a Boiler Incrustation from New Jersey ; by GrorGE A. 
Kornte, Ph.D.—Some time ago Mr. Joseph Harrison, Jr., pre- 
m 
Orange Co., : ysical properties of this incrustation 
Were remarkable enough to suggest a chemical examination. It 
was about half an bak thick, presented a smo ; w 
— and coherent, of a brownish flesh-color, and showed on the 
cture a distinct prismatic structure, the ng ver- 
tically on the a It looked very much like the so-called 
surface. : Rigas
