The Chairman, Dm WILLI~I H. Rou~G Boston, Mass.--Ladies and gentlemen~ we have waited, I think, as long as we can for our president, Dr. James B. Herriek of Chicago, who was to begin the meeting. I am sorry there is not a larger attendance. Some of the speakers would like to have a lantern, and I believe that one is being brought from somewhere--I think in this city--so tlmt the first paper [ will eaI1 for is by Dr. Hurxthal. 1. DR.

Idiopathic Hypertrophy of the Heart in Infants.* ]t would be better to designate the treme~dous increase ia the size of the heart described in the literature as ~'idiopathic hypertrophy" by the term, "hypertrol)hy of unknown etiology," but so few eases have been reported that for the present, to keep the literature on the subject accessible, we have retained the old name. Such enlarged hearts described by Howland in his classical article showe,l hypertrophy and nothing else except in two instances a very small open foramen ovule. He was of the opinion that it was unjustifiable to discard a ease as one of idiopathic hypertrophy merely because it showed likewise a shnple defect. The two kinds of cases, hypertrophy with simple defect and hypertrophy without~ are so similar clinically that one might, before post-nmrtem exanfination of the heart~ swear as go the correctness of a diagnosis, only to find that without a murmur, a simple defect such as a. foramen ovale, an open interventrieular septum or a patent duetus arteriosus would be present, or that with a murmur nothing would be shown except a hypertrophy. We believe that such eases of defects are worthy of reporting as purpose of emphasizing this class trophy of the heart without olher larged to from two and a half to
idiopathic hypertrophy which also have simple a class and we have five such eases. With the we are reporting six eases of idiopathic hyperdefect. In all of the cases the hearts were enfour times the normal size, and in all of them
