was opened at 42-44 The Triangle, by John Wright & Sons Ltd. Stocks are held of the works of most medical publishers and any book not in stock can be ordered. It is hoped that doctors and medical students will make full use of the room for study and reference. They will find a quiet and dignified atmosphere quite unlike that of the ordinary bookshop. John Wright & Sons Ltd. were established as ...

A. Clark[2] has shown that the class of languages which have a context-free grammar whose nonterminals can be defined by a finite set of contexts can be identified in the limit, given an enumeration of the language and a test for membership. We show by example that Clark’s algorithm may converge to a grammar that does not define the input language. We review the theoretical background, provide ...

A recently developed topological mesh modeling approach allows users to change topology of orientable 2-manifold meshes and to create unusual faces. Handle-faces are one of such faces that are commonly created during topology changes. This paper shows that vertex insertion and corner cutting subdivision schemes can effectively be used to reconstruct handle-faces. These reconstructions effective...
