In their relations to diseases the writer of the article unequivo- 
cally accepts the view that they are the cause, not the accompani- 
those of the parasitic invader; and it is now generally admitted 
that the mere admission of a Schizomycete into an animal does 
not necessarily cause disease. Were it otherwise, it would be 
difficult to see how the higher organisms would escape at all.” 
Botanical Journals.—The writer of this note has had during 
the past seventeen years, the period covered by his botanical 
teaching, many inquiries from beginners in botany as to what 
botanical journals it would be best for them to read. The re- 
plies have varied according to what appeared to be the individual 
needs of the inquirers. Recent inquiries from young botanists 
in widely-separated localities suggest the need of a short paper 
by way of guidance to those who would, if they could, read one 
or more botanical journals. 
Nowadays, in any line of work, one who wishes to be pro- 
gressive must read the proper journals. The young teacher who 
expects to keep up with the discoveries in his specialty without 
reading some of the journals devoted to that specialty will find 
himself in a few years hopelessly behind his reading fellow- 
workers. He must read,and he must read the best. He cannot 
afford to read anything less than the best. What shall he read ? 
In answer to this it may be said that it is the duty of every 
teacher to so far hold his “specialty” in check that he shall be 
first and foremost a dofanist, one who has knowledge of, and an 
interest in, all portions of the great science of plants. Let him 
be primarily a botanist, and then, if he has the inclination, sec- 
ondarily a phanerogamist, a caricologist, a pteridologist, a bryolo- 
gist, a lichenologist, a mycologist, an algologist,a phytotomist, or 
a vegetable physiologist, etc. The teacher may, and probab 
should be, a specialist, but he must be a botanist in the broadest 
sense first. His duty to his pupils is to instruct them in botany, —
