"The sun's rays are composed of three parts; lighting, heating, and actinic or chemical rays. These latter interfere with the process of combustion." The above is an extract from Rev. Dr. Brewer's _Guide to the Scientific Knowledge of Things Familiar_, 6th edition, p. 50., which may perhaps prove interesting to C. W. B. At p. 58. of the same book, H. A. B. will find, I think, an answer in the affirmative to his Query (Vol. vii., p. 286.): "Is there such a thing as spontaneous combustion?" C---- S. T. P.

If any of the readers of Mr. Hudson Turner's volume on Domestic Architecture have been under the apprehension that the death of that able antiquary would necessarily lead, if not to the abandonment of that work, to its being completed in a more imperfect manner than Mr. Turner would have completed it, we can assure them that such apprehension is entirely groundless. We have now before us the second part, entitled _Some Account of Domestic Architecture in England from Edward I. to Richard II., with Notices of Foreign Examples, and numerous Illustrations of existing Remains from original Drawings. By the Editor of the Glossary of Architecture._ The editing of the work is indeed most creditable to Mr. Parker, who, though he modestly confesses that if he had not known that he could safely calculate upon much valuable assistance from others more competent than himself, he would never have ventured to undertake it at all, had already given proof of his fitness for the task by the _Glossary of Architecture_ with which his name has been so long and so honourably connected. The work, which supplies a deficiency which the architectural student has {346} long felt, is produced in the same handsome style, and with the same profuseness of illustration, as its predecessor, and will be found valuable not only to archæologists who study history in brick and stone, but also to those who search in the memorials of bygone ages for illustrations of manners and customs, and of that greater subject than all, the history of our social progress.
