The above works, along with the present one, constitute a complete practical and popular Library of Anatomy, Medicine and Physiology. They have all been purposely designed for the instruction of non-professional readers, but at the same time are so scientifically correct, and so complete, that they would serve as text books for Medical students. The favor they have already met with, and the extensive circulation they have attained, is proof that they both meet the wants of the public and enjoy its approbation. _From the Boston Mail, March 7, 1848._ DR. HOLLICK'S SEPARATE LECTURES TO LADIES AND GENTLEMEN ON PHYSIOLOGY.--The importance of adult persons, of both sexes, understanding themselves, and their natural relations, must be obvious to every thinking mind. The present ignorance on these matters is, undoubtedly, the chief cause of the vices and sufferings which so extensively prevail, and our only hope of a beneficial change must be founded on a proper system of public instruction. This instruction is difficult to impart we admit, and there are but few men qualified for imparting it. We have no hesitation, however, in saying that Dr. H. is one of these men. He knows how to preserve in his subject all that intense interest which it intrinsically possesses, and yet to divest it of everything in the slightest degree obnoxious to censure, or even distrust. He has a happy faculty of making every thing easy to be understood, and yet avoiding the slightest approach to undue familiarity. All who attend, express themselves both surprised and delighted, and unhesitatingly recommend his Lectures wherever they go. Many of the most eminent Ladies in our city were among his auditors last week, and were unreserved in their expressions of approbation, both for the Lecture itself, and for the becoming modesty and true refinement that characterised its delivery. The present series, which commence to-day, has been anxiously expected, and will no doubt be numerously attended by both sexes, but particularly by the Ladies, many of whom were unable to gain admission last week.
