from Cape Breton Island, Nova Scotia. But even in the interior, good nlateriaf 

 apparently is not lacking: fine specimens of 6'. papillosum have recently been 

 received from Michigan. Except in regions where the climate is congenial, 

 however, it is to be expected that sphagnums of surgical value will be very local 

 in their distribution. 



In conclusion, information is particularly sought regarding the occurrence 

 in quantity of 5, papillosum, since this species, as already pointed out, has proven 

 the most uniformly adapted to surgical use. 5. papillosum, to a limited degree, 

 of course, can be recognized by its very robust habit and Its commonly yellowish 

 brown to brown pigmentation. Information regarding 5. palustre, S. imhricatum, 

 and 5. magellanicum, where these appear sufficiently luxuriant to be of use, 

 will also be welcome, but these, particularly the last named, tend to be of too 

 poor quality (too much stetn in proportion to foliage, stem too stiff, etc.) to 

 meet the requirements.
