JOHNS HOPKINS HOSPIT.\L REPORTS. VOL. II, 

 NOS. 1-9. 



This report contains three articles. The 

 first is an exhaustive and valuable monograph 

 on pneumothorax by Dr. Emmerson, covering 

 450 pages. The literature of the subject, go- 

 ing back to the works of Hippocrates, and 

 coming down to the present time, is given in 

 the form of abstracts, translations or quota- 

 tions from the original articles. This neces- 

 sitates much more space than is usually de- 

 voted to literature, but it must be admitted 

 that in many respects it is more satisfactory 

 than the references ordinarily made. The first 

 chapter is devoted wholly to these abstracts. 

 In Chapter II., entitled ' The History of 

 I'neumothorax,' the facts stated in the ab- 

 stracts already given are satisfactorily woven 

 together. Chapter III. is devoted to the 

 etiology and pathology of the disease, with 

 clinical histories of cases. While there is 

 much of interest in this chapter, it can not 

 be said that it contains any important contri- 

 bution to our knowledge of the disease. Chap- 

 ter IV., on ' The Mechanism of Pneumo- 

 thorax,' is, in our opinion, the most interest- 

 ing, and in some respects the most valuable 

 part of this monograph. Your reviewer has 

 been especially interested in the work done by 

 Dr. Emmerson, as well as the literature which 

 he has collected bearing upon the composition 

 of the gas accumulation in the chest in this 

 disease. His conclusions are stated as fol- 

 lows:
