Causes of Irregularities in the Devel- 

 opment OF THE Teeth. By N. W. Kings- 

 ley, D. D. S. Pp. 42. 



This pamphlet contains a paper on the 

 above subject, read betbre the Odontologi- 

 cal Society of New York. Irregularity of 

 teeth is shown to arise from three causes : 

 1. During the life of the individual, from 

 cerebral disturbance while the teeth were 

 forming; 2. Or before the individual life 

 commenced, from like causes transmitted ; 

 or, 3. From mixing inharmonious types, 

 large teeth with small jaws. 



On the Cotton-Worm of the Southern 

 States. By Aug. R. Groie. Pp. 6. 



In this paper, reprinted from the pro- 

 ceedings of the Hartford meeting of the 

 American Association for the Advance- 

 ment of Science, Prof. Grote summarizes 

 the results of five seasons' observation of 

 the cotton-worm in the States of Georgia 

 and Alabama. Where the moth first came 

 from, its powers of flight, breeding habits, 

 and the measures to be taken against its 

 ravages, are among the interesting ques- 

 tions discussed. 



The American Engineer, published 

 monthly at Baltimore, begins its third vol- 

 ume in enlarged form. Though primarily 

 this journal addresses inventors and me- 

 chanics, it will be perused with interest by 

 the general reader, who will find in its pages 

 much useful scientific and industrial infor- 

 mation, $1.0U per annum.
