By H. Middleburgh, l), 1939.
The
Hyperthyroidism is rare in children, but the following case report shows that it can occur and that when it does, the eruption of the teeth is materially accelerated. Gwendoline II., aged 4 years 11 months, prematurely born at seven months and weighing three and three-fourths pounds, was fed after three months with patent foods, gaining weight normally. Although never ill she slept poorly and was always nervous. Some nine months before her admission into the hospital typical symptoms of hyperthyroidism manifested themselves, including a pulse of 140 and recurrent attacks of dyspnea and tachycardia lasting several hours. At the age mentioned the maxillary right first permanent molar had erupted and the maxillary left first permanent molar showed through the gum. The right and left mandibular permanent central incisors were erupted, all some two years ahead of their normal time. Several of the cleciduous teeth were carious, and since a pronounced immunit,v to dental decay is a feature of most cases of hyperthyroidism, the presence of caries confirms that the hyperactivity of the gland commenced comparatively recently. The patient made a splendid recovery after thyroidectomy.

A method of making lantern slides of tabular and text matter, which eliminates one step in the photographic process, is to type the data through white carbon paper on black paper. The ribbon indicator on the typewriter is set at position for stencil cutting, to obtain as white an imprint as possible from the carbon paper. The material transferred as white 011 black paper is then photographed in ordinary daylight (artificial light does not give good results), Eastman contrast lantern slide plates being used as negatives. Each negative is bound with a cover glass as an ordinary lantern slide. This method results in slides that show black letters and figures on a white background and avoids the necessity of making positives after the negatives are made. Kymograph records on smoked paper can be mounted on black paper, the legends typed through the white carbon paper, and both the records and the legends will be reproduced photographically as black on white. Simple curves and diagrams can be traced through the white carbon paper onto the black paper. We have been unable to find a white typewriter ribbon on the 597
