Pulmonary Hcemorrhage : its Causes and Results. By Reginald E.
Thompson. (Smith, Elder, and Co.)—When we consider the enormous field for the study of chest diseases that the physicians of the Brompton Hospital are afforded, it becomes a matter of no surprise that they should contribute largely to the medical literature of the day. In the work now under consideration, Dr. Reginald Thompson puts before us clearly and concisely the conclusions at which he has arrived with regard to bleeding from the lung. Whether these views will be accepted by the profession generally we do not pretend to say, nor do we wish to discuss in these pages the grounds upon which they are based. The main question is whether bleeding from the lung is the cause or the result of consumption. According to Dr. Thompson, it is generally the cause. Another important question dealt with is the nature of the hereditary taint transmitted to the offspring of consumptive persons. Dr. Thompson considers it to be a general delicacy of constitution, rather than a distinct tendency to pulmonary consumption. The whole work gives evidence of careful research, and an honest desire to add to medical knowledge.
