front is richly ornamented with carving. 
The plantation and walks about this 
houfe are laid out with more tafte and 
elegance than any I have feen in Scot- 
land. A beautiful river, called the Dive, 
runs through the grounds, and near the 
houfe isan elegant bridge over it, of nine 
arches. All the neighbouring hills are 
covered with pine. Oppofiteto Bamff is 
alittle town called Macduff, belonging 
to the Earl of Fife, who is taking much 
pains toimprove it, and is building a pier 
for the coatling-veflels, which, when 
finifhed, will be fafe and commodious.— 
Leave Bamff, and go through two {mail 
villages, called New Deer and Oid Deer, 
to Peterhead. From Bamffto New Deer, 
about fixteen miles ; the land here b:longs 
chiefly to Lord Fife : a great part of it is 
in a high ftate of improvement: it is 
moftly coru-land, though there is fome fit 
for the fattening of cattle, to which ufe a 
part of itis applied : many of the bullecks 
are fo large, as to amount, when fattened, 
to the value of 251.” 
The letter from our Bamff Correfpond- 
ent, which we have confiderably abridged, 
ftill, however, retaining the fubftance, 
concludes as follows: “ I feela little fore 
at the Editor’s remark upon my piece of 
amber, formerly thrown on the coaft of 
Bamfffhire, as large as a horfe.* You 
may depend upsn that being ftated as a 
fact, under the head of Bamff,or Moray, 
in the Encyclopedia ; and if you think 
it proper to mention fuch authority, I 
fhould be glad of it.” Our Correipond- 
~ ent does not mention the particular Ency- 
clopedia from which he drew his informa. 
tion ; probably it was one of the Scotch 
Encyclopedias; that of Edinburgh, or 
that of Perth, which is the molt recent 
and copious ; but he drew his information 
from fome Encyclopedia or other; and 
this will, no doubt, be admitted as a {uf- 
ficient apology. It may be added, in de- 
fence of our friend, that there are many 
horfes in Bamfffhire and Moray, and 
other parts of Scotland, not exceeding in 
eubical inches a large and well-fattened 
Englith hog, though much higher on the 
legs. Captain Newte, already quoted, 
tells us, that in Morayfhire ** there is 
nothing more common than to fee finall 
horfes, jack-aflzs, ftotts, or two-year old 
bullocks, and even boar-{wine, all yoked 
together, and dragging in good-fellowfhip 
the flight plough through the light and 
pliant ioil.’*. From hence we may form

To the Editor of the Monthly Magazines 
SIR, 
€I doubt not but I fhall make it plain.” 
Bacon.* 
ORD MANSFIELD told a friend of 
his, that he had one day fome doubt 
upon a very difficult point of law; but 
that he made a fyllogifm of it, and cleared 
it up to his fatisfa¢tion. If then the fol- 
lowing Mathematical expofition of a very 
common, and I believe frequently unno- 
ticed, error in conftru€tion, be worthy a 
place in your Magazine, its value may 
perhaps be lefs in relation to the parti- 
cular phrafe which it concerns, than asa 
hint toward the application of a fimilar 
teft in the folution of other grammatical 
quefticns. 
I. 
t. I think it. 
I doubt it. 
2. Ido not doubt that I thall; or, 
I do not thizk that I fhall xot. 
3- I do wot doubt that I fhall; or, 
I thivk that I fhall. 
eee Thus, 1. doubt and think are oppo- 
Ite): 
2. doubt is equivalent to think not; and, 
3. think is equivalent to doubt not. 
Or, adopting the pofitive and negative 
figns of algebra, 
2. + doubt== — think; and 
3. + think = — doubt. 
IT, 
1. I do not think that I fhall. 
I do not think dat I thall. 
2. I donot think Sut I fhall; or, 
I do not think ¢hat I thall zor. 
3. Ido zot think dui I fhall; or, 
I think ¢hat I fhail. 
Cor. Thus, 1. that and but are oppofite ¢ 
2+ but is equivalent to that not ; and 
3. that is equivalent to but not. 
Algebraically, 
2. + but = — that; and 
3. + that = — but.

Then, 
1. 1 do not doubt that I-fhall (1. 2, 3.),
