be placed in clear water and floated out by running under them, the 
paper on which they are to remain permanently,—either the regular 
mounting paper, or a thinner white kind, which when dry can be 
pasted on the common herbarium sheet. 
Finally, but first in importance, as you collect and put in port- 
folio, be particular to write the name of each species, if known, but 
by all means, the locality and date of collection, with any other 
descriptive remarks regarded necessary, on one of the lower corners 
of specimen sheet. On no account neglect this important point to 
your subsequent regret and the impairment of the specimen. This 
should be written as you are putting in press or portfolio. Labels, 
if preferred, can be used, instead of writihg on margin of specimen 
sheets. 
§ 247. Conomitrium Julianum.—July 22d I had the good 
fortune to find an abundance of this rare and curious moss in full 
fruit. It was on the inside of a walled-up spring a few rods West 
of Mt. Carmel Station, Hamden, Connecticut. The moss grew in 
thick tufts, like some alga, just at the water's surface, and beneath it. 
It also was found lining a barrel some rods away, whither the water 
is conducted from the spring. Taking my gatherings home, and 
floating them out to mount, as one does a seaweed, I found the sides 
of my dish covered with hundreds of the detached capsules, just as 
Dr. Schimper relates to have happened with Mr. Noellner, when he 
collected the same plant in 1839 in Baden. Since the water in a 
spring or stream is drawn up a little at the margin by capillary 
attraction, just as in the dish I employed, it is probable that these 
little capsule float up to the extremest edge of the water, and that 
there the spores germinate and grow. I will send specimens to any 
persons asking for them. D. C. Eaton.
