174 JOURNAL OF THE [October, 



Whereas this Society has received with sorrow the announce- 

 ment of the death of Mr. Joseph Zentmayer, which occurred at 

 Philadelphia, Pa., on March 28th, 1888, it is hereby 



Resolved: — 



1. That in the death of Mr. Joseph Zentmayer the laborers 

 in the various branches of science employing optical instruments 

 have lost the inspiriting presence and helpful cooperation of 

 an eminently intelligent and successful author, inventor and 

 mechanician, whose knowledge of optical principles has been 

 attested by his brilliant publications, whose attainments have 

 been recognized by his election to membership in various 

 organizations, and whose mechanical skill and conscientious 

 carefulness are still shown in the large variety of instruments 

 issued from his establishment. 



2. That a record of this action be forwarded to the family of 

 Mr. Zentmayer as a token of our heart-felt sympathy with them 

 in this bereavement.
