ferently. Those farmers who make the potato a special 
object of cultivation use the seed, but generally the plants 
obtained during the first year have no tubers and do not 
flower. A large number of the varieties that are now 
raised have originated from seed, and they, as well as the 
others are found to be infected with the fusarium. It 
was then, only after the fusarium was acclimated as well 
as the plant,that we could obtain from seed the result that 
we desired, and that the tuberculization appeared to be 
hereditary. | 
Now fusarium, according to Griffith and Henfrey in the 
Micrographic Dictionary,is a genus of fungi not very sat- 
isfactorily distinguished from fusisporium, and fusispori- 
um grows upon vegetable substances, often when decaying 
having spindle shaped spores. There are several species 
of arose color, At any rate this discovery of M. Bernard 
is important and seems to be genuine. The microscopic 
fungi are looking up. ! 
Formaldehyd and Small-pox. 
The medical profession has made a discovery,—that 
small-pox is a filth disease which yields readily to cleanli- 
ness and to disinfection. It has discovered that makers 
of vaccine are incompetent, if not careless, and that even 
good vaccine very easily deteriorates. Strangely coincident 
with these discoveries, a throng of ‘‘mental-healers”’ has 
flooded our papers with protests against vaccination. The 
latter know nothing of formaldehyd disinfection but un- 
wittingly paved the way for its acceptance. 
Speaking to doctors only, in the Medical Society of Cleve- 
land, behind closed doors, Martin Friedrich, M. D., Health 
Officer, said that commercial bovine virus is dangerous, 
that it is too unreliable in cases of epidemic, that frequent- 
ly it will not take, that popular feeling is seriously against 
it, that sepsis results and makes serious trouble. He told 
how he had to lie to patients as to “the ugly suppurating 
wounds’’ he had made. He said that such sepsis, with all
