105*C. It crystallised with one mol. of water and had the composition C l0 
H| S Oj+H,0. When warmed with dilute sulphuric acid it was decomposed, 
with the formation of thymol. The other new body was an erythritol, 
melting at 128° to 18l°0 , after drying in vacuo, and having the composition 
C )0 H I0 O t + HjO. Whfen boiled with dilute sulphuric acid, it was decom- 
posed, the products of decomposition including a ketone with a strong odour 
of menthone, and a crystalline phenolic substance, melting at 80°to8I'C. The 
formation of more than one glycol by the hydration of the re-arrangement 
product of ascaridol may be explained by adopting the view of Wallach, 
whose results indicate that ascaridol is a 1— 4-and not a 8—0-peroxide. Oxida- 
tion of the erythritol yielded an acid, C, 0 H ia 0„, which was regarded as one 
of the modifications of a rf-metylisopropyl a a-dihydroxyadipic acid differing 
in its properties from the two modifications previously described by Wallach. 
Oxidation of the a-glyeol yielded an acid agreeing in Us reactions with the 
structure of 1—4 clneollc acid (J. Ch. I. April 15th, 1018, p. 879.)
