irrelevant. Chemistry and the relations between science, technology, and industry are well surveyed by Crosland and Cardwell respectively. Forbes's essay on mathematical cosmography is not a comprehensive account but the story (albeit interesting) of a few German cartographers. Compared with other recent collections of essays in the history of science, this volume parades no party line: witness...

Ueber Das Verschwinden Der Θ-functionen

The polysulfonylamines bis(methylsulfonamido) sulfone and bis(trifluoromethylsulfonamido) sulfone.

Bis(methylsulfonamido) sulfone, C(2)H(8)N(2)O(6)S(3) or SO(2)(NHSO(2)CH(3))(2), was synthesized from imidobis(sulfonyl chloride), HN(SO(2)Cl)(2), and bis(trimethylsilyl)methane, CH(2)[Si(CH(3))(3)](2), in chlorotrimethylsilane solution. In the solid state, there are two independent molecules linked by two N-H...O hydrogen bridges into infinite chains parallel to the b axis. The central S atoms ...

Benzhydryl phenyl sulfone

In the title compound, C(19)H(16)O(2)S, the sulfur-bound phenyl group is approximately parallel to one of the two phenyl rings of the benzhydryl group, making a dihedral angle of 12.53 (10)°, and forms a dihedral angle of 41.25 (9)° with the other phenyl ring. In the crystal, weak C-H⋯O inter-actions form a two-dimensional network propagating along the bc plane.
