As indicated in the title, this work is an extension of the first series of practical lectures which were published in 1925. They cover a wide range of subjects of interest to all medical men. Each lecture is complete in itself, and represents the present day knowledge and opinion of each subject discussed; they were delivered chiefly by physicians and teachers of prominence in the New England states. Numerous illustrations enhance the value of the work. There is every reason to predict that this series of lectures will be received with as great enthusiasm and commendation as was the first series.
