Very good secondhand. 

Split into four parts. Part one comprises 408 pages of the well-known polycrests. Part two has 183 pages on smaller remedies. Part three is a companion to Allen's Keynotes and explains any phrases and terms which the student may encounter. Part four is a 14 page glossary.

Books and Allied, Calcutta. Third edition reprint 1999. 

Very substantial paperback with loads of content. The cover is somewhat worn. 

Dr Dubety was a favourite teacher of numerous British students that visited Calcutta about 35 years ago. 

Highly knowledgable.
