THE ANNUAL MEETING AT CLEVELAND. 



E. H. GRIFFITH. 



IT has been my good fortune within the past few weeks to 

 visit a large percentage of the members of the American So- 

 ciety of Microscopists, also other good workers, at their homes. 

 Commercial pursuits in many of the larger cities of the States 

 have frequently given me this privilege for years, and it is a 

 pleasure to be able to report a constantly increasing interest in 

 microscopical research and a large addition to the army of mi- 

 croscopists. New societies are being organized ; new fields of 

 investigation are being opened; new discoveries are being 

 made ; and it is probable that more real advancement in micros- 

 copical research in America has been made since the organ- 

 ization of our Society than for the entire century previous. Our 

 eighth annual meeting, to be held in Cleveland in August, bids 

 fair to be better attended and more practical than any previous. 

 There are many earnest working microscopists who have at- 

 tended each meeting of the Society, who now look forward to 

 these annual gatherings with intense interest. One by one of 

 our members are leaving our ranks, however, and joining those 

 who see face to face, and not through a glass darkly. We miss 

 them greatly, but we welcome those who remain ; also new re- 

 cruits to our numbers. Cleveland is a beautiful city, and in it 

 are found earnest workers who will welcome us with great cor- 

 diality. Then let us enjoy their hospitality and improve a 

 golden opportunity. 



THE MERITS OF WHITE ZINC CEMENT. 



W. H. WALMSLEY, OF PHILADELPHIA. 



HAVE noticed of late your many references to the merits of 



I 



White Zinc Cement, especially those in the May number of 

 The Microscope, referring to Cole's slides finished with it. I 

 may mention as an item in this connection, that in 1871 I sent 

 by the hands of a friend then going abroad a dozen of my double 

 stained vegetable sections, finished in white zinc, with a blue 

 line, (such as I first used in 1867), to Mr. Cole. In due course 

 an acknowledgement arrived from him speaking enthusiastically 

 of the appearance of this finish, and asking for some of the
