THE CHURCHES OF THE MIDDLE AGES: or, Select Specimens of Early and Middle Pointed Structures; with a few of the pures; Late Pointed Examples, Illustrated by Geometric and Perspective Drawings. By HENRY BOWMAN and J.S. CROWTHER, Architects. Containing Illustrations of St. Peter's Church, Thrukingham, Norfolk; St. John's, Cley, Norfolk; and St. Andrew's, Heckington, Lincolnshire. To be completed in Twenty Parts, each containing Six Plates, Imperial folio. Issued at intervals of two months. "Ewerby is a magnficent specimen of a Flowing Middle-Pointed Church. it is most perfectly measured and described: one can follow the most rcondite beauties of the construction, mouldings and joints, in these Plates, almost as well as in the original structure. Such a monograph as this will be of incalculable value to the architects of our Colonies or the United States, who have no means of access to ancient churches. The Plates are on stone, done with remarkable skill and distinctness. Of Heckington we can only say that the perspective view from the south-east presents a very vision of beauty; we can hardle conceive anything more perfect. We heartlily recommend this series to all who are able to patronize it."--_Ecclesiologist_, Oct. 1849.
