lines of classification have been obliterated or covered up. Vast additions have been also made. At no former time was there half the amount of actual observation in this field which exists in it now; and it is well that there should be so skilful a workman as Mr. Wilson to avail himself of the accumulating materials. His treatises show how very just is the estimate of his powers given to the public in _Peter's Letters_ considerably more than twenty years ago, at a time when he was comparatively little known. But we cannot enumerate a tithe of the masterpieces of the British Encyclopædia. Judging from the list of contributors' names attached to the index, we must hold that Moderatism in the field of literature and science is very much at a discount. But there is no lack of data of very various kinds to force upon us _this_ conclusion. Among our sound non-intrusionists we find the names of Lord Jeffrey, Sir David Brewster, Professor John Fleming, Professor David Welsh, Professor Anderson, Dr. Irvine, the Rev. Mr. Hetherington, the Rev. Mr. Omond, Mr. Alexander Dunlop, and Mr. Cowan; whereas of all the opposite party who record their votes in our church courts, we have succeeded in finding the name of but a single individual, Dr. John Lee. Why has Dr. Bryce thus left the field to the fanatics? had he nothing to insert on missions? Or could not Mr. Robertson of Ellon have been great on the article Beza? Was there no exertion demanded of them to save the credit of the Earl of Aberdeen's learned clergy? One of the main defects of omission in the work (of course we merely mention the circumstance) is the omission of the name of one very great non-intrusionist. Ethical and metaphysical philosophy are represented by Dugald Stewart and Sir James Mackintosh; mathematical and physical science by Sir David Brewster, Sir John Leslie, Playfair, and Robinson; political economy by Ricardo, M'Culloch, and Malthus; natural history by James Wilson and Dr. Fleming; Hazlitt and Haydon discourse on painting and the fine arts; Jeffrey on the beautiful; Sir Walter Scott on chivalry, the drama, and romance; the classical pen of Dr. Irvine has illustrated what may be termed the biographical history of Scotland; physiology finds a meet expounder in Dr. Roget; geology in Mr. Phillips; medical jurisprudence in Dr. Traill. But in whom does theology find an illustrator? Does our country boast in the present age of no very eminent name in this noble department of knowledge--no name known all over Scotland, Britain, Europe, Christendom--a name whom we may associate with that of Dugald Stewart in ethical, or that of Sir David Brewster in physical science? In utter ignorance of the facts, we can, as we have said, but merely refer to the omission as one which will be assuredly marked in the future, when the din and dust of our existing controversies shall be laid, and when all now engaged in them who are tall enough to catch the eye of posterity, will be seen in their
