was obtained alone by condensation of hydroxymethylene camanek with benzalailes The 
«-form could be quantitatively changed into the @-form (m.p. 112°) by boiling with pyridine; 
and the @-form converted completely into the «form by the action of ultraviolet light. 
Further, the following derivatives were prepared, and similarly examined:— Methylene — 
camphor-p-nitranilide, «-form (m. p. 180 to 181°), 8-form (m. p. 151 to 152°); methylene ee 
camphor-p-phenylene diamine (m. p. 153 to 154° and m. p. 163°); methylene camphor- 
p-phenetidine, -form (m. p. 111 to 112°), «form (m. p. 166 to 167°); dimethylene — 
camphor-p-phenylene diamine (m. p. 276 to 277°); methylene camphor diethylamine — ie 
(b. p. 171.5 to 174° at 9mm.); methylene camphor piperidine (b. p. 203 to ee a 
11 mm.); methylene camphor-tetrahydroquinoline (b. p. 118 to 120° at 11 mm.), methylene — 
camphor urea (m. p. 197°); methylene camphor ethylurethane, «form (m. p. 162), 6-form y

On treating the last-named compound with acetic anhydride and phosphorus oxy- 
chloride methylene camphor-N-acetylanthranilic acid (m. p. 185°) (V) and the ee c
