piece of investigation, and proves the singular address and skill of our 
author »—for, furnished only with a few bones of the trunk and extremi- 
ties, without a fragment of tooth or of gy ter to serve as a guide to the 
animal’s position in the zoological scale, he has been able to refer it to

his our testimony of the success .with which you have Wetted cs re 
great science of comparative ‘zoology, to which you have devoted your 
powers. I trust it will add to your satisfaction, to consider, that the sub-

number of Jameson’s Journal gives as the results of his observations on 
the Liverpool and Manchester Railway, that a speed much greater than 
the present twenty five miles per hour, may be used with safety. The. 
question is, whether with a velocity of three or four times the usual rates, 
the engineer can preserve perfect command of the powerful Iscomhotives 
. Mr. Sang remarks, that “with the velocity of twenty five 
miles an hour, even when exposed to the current of air, there was not
