the same manner as others. We cannot deny that the figures given indicate that 

 his conclusions appear legitimate, and yet, we may well question the propriety of 

 assuming quite so much from the study of dead remains. It does not appear that

 tended to make it so large as the present number, but the

 so much the result of carelessness on our part as of inexperience 

 in proof reading. We hope they may be overlooked in this 

 our first number. — Ed.
