hohutijric Acid. (CH 3 ) 2 Cri.COOH. 
From Dr. Peuktn. On distillation the sample boiled between 152°’5 and 154°. 
n = 23°'2, ^ = 31° (emergent column). Bar. 751’5 millims. Corrected and reduced 
b.p. 154°‘03. A second observation of the boiling-point in another apparatus gave 
as the boiling-point limits 152°'4 and 154°'3. n =.23°0, t = 27°'5. Bar. 7464 
millims. Corrected and reduced b.p. = 154°'00. 
The observations for viscosity gave ;—
