aided, and may serve as an encouragement and a model to other 

 practitioners situated at a distance from the more active centres of 

 scientific industry. Dr. Michel's history of an early ovum is not 

 without interest, though its illustration is less exquisite than the 

 "Icones" of Wagner, and the style is wanting in the simplicity 

 which should belong to an anatomical description. Dr. Harden's 

 Essay on Isopathia, agrees with the general belief in maintaining the 

 similarity of scrofula and phthisis, but will hardly be thought to 

 have established the doctrine, that Bright's disease is isopathic with 

 these affections. Why molluscum should come under the same head 

 is hard to explain. In the days of isomerism and isomorphism, it is 

 natural enough for a medical observer to be pleased with the thought 

 of introducing some such parallelism of elements into medicine, but 

 it may be questioned, how much is gained by the somewhat pro- 

 miscuous erudition and finely drawn propositions of this elaborate 

 essay, beyond a harmonious name for a well known principle. Dr. 

 Kelly, of Mobile, has given an account of yellow fever as this dis- 

 ease has presented itself to his own notice, written in clear and 

 simple language, and keeping more closely than many writers on 

 this subject have done to the strict results of observation. Some 

 remarkable surgical cases and operations, a case of incision of the 

 os uteri during labour on account of its partial occlusion, some 

 researches on the structure and functions of the ciliary processes, and 

 the case of the murderer Freeman, with a long review of some of 

 the Boa Vista fever documents finish the list of original articles. 

 In this number, October 1847, appears a new and distinct head of 

 medical intelligence, entitled ether inhalation as a means of annulling 

 pain. It is remarkable, that as so much patient deliberation was 

 shown in preparing the abstract of what was before the public, on 

 this subject, an article like that of Dr. Pickford should be admitted, 

 but more remarkable still, that any sensible reader should have been 

 frightened out of receiving the last great gift of Mercy, by the asser- 

 tions of such a writer, as would appear to have happened in at least 

 one instance. 



In the number for January, 1848, the leading article is Dr. Leidy's 

 paper on the Comparative Structure of the Liver. This is unques- 

 tionably the most exact and complete Essay in the department of 

 microscopic anatomy which has appeared in any American Medical 

 Journal. The patient accuracy of the measurements, the finish and 

 clearness of the numerous illustrations are nothing more than would 

 have been anticipated by those who know the zeal and talent of this
