succeeding March was warmer (though not much) than any of the winter 

 months, 6 degs. warmer than our past March, and of course the early 

 development of vegetation did not suffer destruction as it did in the last 

 few weeks. 



The quantity of rain (including snow, which by the way was unusually 

 heavy) was also more than 3 inches above the average, viz., about 6| 

 inches. If we examine the records, we find that in 7 out of the previous 

 40 years the quantity equalled or exceeded that of last March ; and eleven 

 years ago (1865) it reached the enormous amount of 8.61 inches. All the 

 seasons which followed such a wet March, exhibited a large, and some of 

 them an excessive, quantity of rain. 



Afril 17, 1876. 

 Chas. V. Riley, President, in the chair. 



Twelve members present. 



Several communications were read by the Corresponding Sec- 

 retar}'. 



At the request of the President of Roanoke College, Salem, 

 Va., a full set of the Transactions, except No. i of Vol. I., were 

 sent to that institution. 



G. J. Engelmann exhibited a fragment of the jaw of a mound- 

 builder, from the collection of Dr. Richardson, showing what was 

 thought to be a third set of teeth. Dr. Forbes was of the opinion 

 that these teeth were those of the second set, in an abnormal 

 position. 



Mr. Todd made some remarks on the cave habitations of the 

 Colorado canyon. He thought the caves at the top of the canyon 

 sides might have been made when the river was cutting through 

 the rocks immediately below the caves. 



Judge Holmes took grounds against this idea, pointing out that 

 none of the caves are now inaccessible, and that it was therefore 

 unwarranted to assume such an antiquity* for these cave-dwellers 

 in order to account for the existence of the caves. 



This view was shared by other members.
