This work shows the result of careful and painstaking observation on the effect of obstruction of the coronary circulation. The subject is considered from the experimental and clinical sides, is well treated, succinctly set forth and accompanied by a fairly comprehensive bibliography.
The first portion of the book is devoted to a review of the anatomy of the coronary circulation. Diagrams and photographs assist the reader in visualizing this. In the experimental production of coronary occlusion several methods were used. Ligature, before and after section of the vagus and sympathetic nerves, was employed to obstruct various branches of the coronary arteries. Infarction was produced in numerous places by the use of alcohol and silver nitrate, and, lastly, embolic infarction was caused by iodized poppy-seed oil 40 per cent, charcoal and lycopodium powder.
The immediate and ultimate effect of these procedures is discussed in relation to the electrocardiogram and to the
