These varieties of tobacco all burn excellently (the maximum comparative 
capacity of holding fire being over 120 seconds in every case); they contain 
much potash and little chlorine. The excellent quality of tobacco, obtained 
from plot 5 proves that lime and phosphoric acid were of no special benefit to this 
soil. Whether these materials produced a beneficial effect upon the quantity, 
is not clearly demonstrated by the figures at hand. Unfortunately, the plan 
of experiment did not include a plot fertilised with neither potash nor nitrogen, 
which would have offered better means of comparison.

NOTHS ON THE NATURAL HISTORY AND PREVENTION OF 
TEXAS FEVER.* 
By J, SIDNEY HUNT, M.R.C.S., 
Government Pathologist. 
Tue “tick. plague,” taken as a whole, is a very large subject, and it is one that 
presents so many different aspects—each nore or less interesting and important 
—that it was no easy matter to determine what particular one to select for 
consideration this evening. I might, for instance, attempt to compress, within 
limits which should not unduly tax your patience, a general outline sketch 
of the whole tick question. But this has been rather hackneyed. And it 
could, I think, serve no very useful purpose to inflict upon you once more the 
whole history of the tick and the disease. You are, 1 am sure, perfectly well 
acquainted with the tick and his ways, and his general wickedness, and are 
also, I am afraid; not unfamiliar with the disease. Or I might, again, 
confine myself exclusively to what may be called the mechanical application of 
the inoculation process; but this also has been repeatedly described, and is in 
itself so simple that it can be easily learned and perfectly well carried out 
by anyone who has once seen it done, as I have already had an opportunity of 
showing you; and to further occupy your time with such a matter would, T 
venture to think, be neither interesting or complimentary. 
«1 Instead of any such topic, I shall therefore endeavour to present for your 
consideration some other aspects of the subject which have been less frequently 
dealt with, but which appear to me of primary importance if we would have 
a clear view of the nature and causes of the disease we call “tick fever,’ and 
of the means at our disposal of combating it. 
THE NAME OF THE DISEASE 
Before getting to work on the particular patch I have chosen, I must, 
however, try and, clear the groand of some obstructions, which cumber it and 
impede our view. I mean the variety of names that we haye for what is essentially
