78 JOURNAL OF THE [April, 



" The first cover, with its appropriate label, is used to support 

 the first watch-glass with its macerating specimen. The second 

 cover, with its label and Watch-glass, is placed in position upon 

 the shoulder of the first cover, and the operation is repeated 

 until six disks supporting six watch-glasses, capped by a seventh 

 disk, used literally as a cover, rise in a column about 4^ inches 

 in height. This column, or nest of covers is not easily over- 

 turned or jarred out of position. 



" If several such nests of specimens are placed in a shallow 

 open box, like a cigar-box with the lid removed, they can be 

 easily moved all together without much risk of upsetting, and 

 any one specimen can be easily distinguished by its label, and 

 instantly secured for manipulation. 



" Such wooden covers retard, but do not prevent evaporation. 

 At the ordinary temperature of a living room, sixty drops of 

 water in one watch-glass will be retained from forty-eight to 

 sixty hours. For maceration in a mixture of glycerine, water 

 and alcohol, where the gradual evaporation of the water and 

 alcohol is desirable, they answer admirably. The specimens 

 can be kept in the concentrated glycerine indefinitely. 



" Suitable deep watch-glasses may be purchased of Albert 

 Berger & Co., 47 Maiden Lane, New York City, for one cent 

 each. The covers can be turned for about three cents each. 



" At the suggestion of Dr. A. A. Julien, such covers were 

 treated by immersion in hot paraffin, and their retaining power 

 was found to be greatly increased, Sixty drops of water could 

 be retained in any of the respective glasses for about seven days. 

 Such paraffined covers can be made for about five cents each."
