CRITICAL NOTICES.

"Of all the popular Tours, of which British literature has recently been so prolific, this is immes-
surably the best. To attempt an analysis of a work embracing such a treasure of anecdote and
instruction, would be an idle task. There is no class of general readers which may not derive
pleasure and profit from the perusal of this volume."-BALLOT.

"Dr. JOHNSON is a vigorous and independent thinker, while his opinions are slightly tinctared
with cynicism, which gives them an agreeable relish. His style is clear, bold, and expressive; so
that when he least aims at effect, he leaves a more vivid impression on us of the object of his
reflections, than others would by an elaborate description."-MORNING HERALD.

"The author, out of his abundant stock of knowledge and reflection, has constructed a volume
with which all classes will be pleased."-ATLAS.

"The medical portion embraces numerous remarks which we would recommend all invalids and
their medical advisers to peruse, before they decide upon the dangerous experiment of foreign
travel."-SPEctator.

"In his descriptions of the different countries he passed through, and the many objects of cu-
riosity that attracted his notice, Dr. JOHNSON has preserved a freshness and originality, that reflect
high credit upon his talent, as a writer and acute observer."-LONDON MED & PHYS. JOURN.

"The present publication is the most entertaining and edifying that has issued from the press
for many years."-GAZETTE OF HEALTH.

"This work is so spirited, so full of sound moral reflection-so correct, and so impartial, that
we scarcely know where to find its equal. It is a classical and philosophical tour. It is impossible
to dip into any part of it, without having the attention rivetted and the fancy pleased."-LONDON
