The Treasurer presented his annual report, which on mo- 

 tion was referred to a committee consisting of Mr. Edwards 

 and Mr. Redfield. 



On motion of Mr. Murray, Dr. Hough was appointed a 

 special correspondent to send accounts of the proceedings 

 of the Institute to the Historical Magazine. 



Adjourned. 



January 17, 1860. 



The Institute met: present, Messrs. Carroll, Edwards, 

 Hall, Hough, McCoy, Munsell, Murray, Pease, Pruyn, Red- 

 field, Vanderpoel, Van Santvoord, Willard, Averill, Shep- 

 erd, Jackson and Brown. 



The president, Hon. J. V. L. Pruyn, occupied the chair. 



The Secretary announced the donation to the library of 

 the Proceedings of the Essex Institute. 



Mr. Redfield, from committee appointed to audit the 

 treasurer's account, reported that they had examined the 

 treasurer's vouchers; and had, after correcting a slight 

 omission, found a balance in the hands of the treasurer of 

 $69.82. 



Prof. Hall then presented a communication on the Genus 

 Eurypteris. 



He then proceeded to describe the genus, illustrating his 

 remarks by exhibiting specimens of the various species, and 

 also showing its analogy with the king crab of the present 

 era. 



He exhibited a restored engraving of a perfect specimen 

 of this animal, stating that he had introduced into this re- 

 storation no single characteristic which he had not actually 

 seen in one or the other specimens he had examined. 



Prof. Hall closed his communication by explaining the 

 geological position in which this genus is found, both in 

 this country and Europe, and pointing out a mistake in 

 the relation of some of its parts, into which he supposed 

 English geologists to have fallen.
