XIX.—On an apparently new form of Holothuria

Semirelativistic Hamiltonians of apparently nonrelativistic form.

We construct effective Hamiltonians which despite their apparently nonrelativistic form incorporate relativistic effects by involving parameters which depend on the relevant momentum. For some potentials the corresponding energy eigenvalues may be determined analytically. Applied to two-particle bound states, it turns out that in this way a nonrelativistic treatment may indeed be able to simula...

An Unsual form of Measles Meningoencephalitis

EFFECT OF IODINE DEFICIENCY ON I.Q.LEVELS OF APPARENTLY NORMAL INHABITANTS OF AN ENDEMIC GOITER AREA

An Apparently Undescribed Infectious Exanthem *

During the past few years, patients with an unidentified acute febrile illness have appeared on the wards of the New Haven Hospital. They present similar signs and symptoms. We have been unable to recognize this syndrome as that of any of the known infectious diseases. We believe that it may be a new disease and we are taking this opportunity to report eleven cases seen in the past five years, ...

An Apparently Successful Case of Cardiac Massage

ago. Present confinement.?The membranes ruptured with the onset of labour and it was decided to apply forceps on account of primary uterine inertia which was contributed to by a cicatrical contraction in the vaginal canal about two inches above the vulva. Under chloroform ana;sthesia this was manually dilated and as forceps were being applied the patient suddenly stopped breathing. The forceps ...
