The completion of the hospital gave Monro the opportunity of delivering clinical lectures on surgery, while Rutherford from 1748 gave clinical lectures on medical cases. Monro himself was present at every _post mortem_ examination, and dictated to the students an accurate report of the case. It was said of him “it is hardly possible to conceive a physician more attentive to practice, or a preceptor more anxious to communicate instruction.” His first and perhaps best known work was his Osteology, published in 1726, and translated into several foreign languages. A French edition appeared in folio with excellent engravings by M. Sue, demonstrator to the Royal Academy of Paris. A treatise on the Nerves followed; and later, a series of Medical Essays and Observations, many by Monro, was issued by him, as the result of meetings of the principal medical men in Edinburgh, which flourished for some years. Another interesting work of Monro’s was his treatise on Comparative Anatomy, in which he proposed to illustrate the human economy by the anatomy of such vertebrate animals as he knew. But the contrast is astonishing between Monro’s knowledge and that of the present day. He divides quadrupeds into carnivorous and herbivorous; fowls into those that feed on grain and those that feed on flesh; fishes into those that have lungs and those that have not. He remarks that the fishes that have lungs differ very inconsiderably from an ox or any other quadruped, and are not easily procured; consequently he omits all account of them. Moreover, he says, “as the structure of insects and worms is so very minute, and lends us but little assistance for the ends proposed, we purposely omit them.” He has a strangely unpenetrating view of the relation between an oyster and a sensitive plant. “What difference is there betwixt an oyster, one of the most inorganised of the animal tribe, and the sensitive plant, the most exalted of the vegetable kingdom? They both remain fixed to one spot, where they receive their nourishment, having no proper motion of their own, save the shrinking from the approach of external injuries.” Dr. Monro’s writings generally are not inviting to quote from, being written in a plain and rather bald style, with very little attempt at illustration.
