Magnetic sasceptibilities of ^afew aliphatic and ammatic liquids and water have h e n investigated at di%erent tempemtares (from m m temperature ta 80aC.), In the case of water, like the o h m t i w s of Piccard, Johner and Cabrem,1 it is found that its ~pecifib diamnpetia uasceptibility _inareassawith rise of temperntnre. In the erne of dip- practically na change is obeemed, but the dismaguetism of atornrtim, mad particnhrly nibbenzene, ~ h o m a definite decmse with rim of h p e r s - ture. f t is we11 known that the eromatiw erbibit a s b m g m mqgetic birefringeaca than the aliphatim. Alm tbe magaetio birefriageaeeef ^a liquid decreases at higher temperatom, bemuse the &mt of is to d i ~ t u r b the molecul~r orlentstion prodad by the ^magaeticr field. It is therefore snggeeted that the deemwe in the diamwrtism of a h a might also Im due ^totheir different degrees of molwahr orien~atioa m t different temperaturee,
