Thewhole model is quite light and easy to handle, and weighswith all the viscera in place fourteen and one half pounds. These models have been found very useful in section teach-ing, as in the dissecting room the student often fails to getan exact idea of the shape and relations of the various organs,as they are usually soft, and impressions made on them byneighboring viscera are generally absent. There are sev-eral details about this model which are unusual or even ab-normal,—the shape of the stomach especially, the positionof the duodenum and right kidney, the size of the csecum 84 MODEL OF THE THORACIC FIGURE VII.

To be of any value, however, such a model mustrepresent the exact anatomical conditions found in a givensubject, and no attempt should be made to improve on na-ture. That is what has been done here with great care, with,the exception of the supra-renal capsules, and I rather doubtthe wisdom of what was done in that case. It is only bythis careful representation that any correct idea can be ob-tained of the variations in the shape and relations of organs,and from a study of models prepared in this manner it maybe found that there are wider variations within normal limitsthan one would suppose. Even if the conditions found hereare not perfect from an anatomical point of view, they arecertainly interesting for clinical study. ARTICLE IV. EMPYEMA IN CHILDREN. By FREDERICK
