Resolved., that the N. Y. M. S. approve of the resolutions 

 adopted by the National Microscopical Congress, at Indianapo- 

 lis, August 17th, 1878, making the i-ioo mm. the standard 

 for micrometry in the U. S., and recommend the same unit 

 for universal use. 



The next thing for us to do is to make proper arrangements 

 for receiving the reports upon this subject from other societies, 

 and filing them ready for publication or preservation in proper 

 form. 



There is, however, more that we can accomplish in this mat- 

 ter that will be of the greatest benefit to science for years to 

 come. 



I make the following suggestions : 



The New York Microscopical Society should first endeavor to 

 secure the immediate co-operation of four other societies, each 

 one of which should appoint a competent man to represent it 

 at some designated place, for the purpose of obtaining our 

 standard centimeter and its divisions. 



Prof. W. A. Rogers will be ready before long to furnish six 

 micrometers to five regularly appointed representatives, for 

 careful measurement. These micrometers, if found sufficiently 

 exact to meet the requirements demanded by the Congress, 

 shall then be accepted as our standard, and one will go to 

 each of the societies represented, and the sixth to Prof. Rogers 

 himself, to serve as his standard to work from. 



When this has been accomplished, and we have our standard, 

 we must have some distinguishing mark for every true standard 

 sold, and it must be copyrighted to prevent its use upon all 

 others. At present Prof. W. A. Rogers alone can make the 

 true standard, for he alone has the means for obtaining a true 

 inch, or centimeter. Still, in future, others will doubtless copy 

 from our standard. Therefore, the copyright mark should not 

 be in the possession of an individual, but rather of a chartered so- 

 ciety like our own. 



I propose that a committee be appointed to prepare designs 

 for such a label, and also to communicate with other societies 

 to obtain their sanction for our action in this matter. 



This label should be in charge of a' special committee of the 

 society, and this committee must allow no one to use it until 

 fully satisfied as to the accuracy of the micrometers for which 

 it is intended and after formal action by the society.
