Dupin’s Force Navale. 213 
which here receive the author’s special and favourable notice, are 
the new smithery erected under the inspection and upon the 
plans of Mr. Hall ; Mr. Hookey’s means of binding timber ; the 
saw-mills erected by Mr. Brunel; the extensive and beautiful hy- 
draulic works carried on at Sheerness by Mr. Thomas under 
the direction and according to the plans of Mr. Rennie, &c. 
At Portsmouth as well as Chatham Mr. Dupin describes the 
buildings, docks and machinery, for which we are indebted to 
Gen. Bentham, formerly superintendent of our naval works. 
Mr. Dupin gives also very accurate descriptions of the great 
naval hospitals, of Haslar at Portsmouth and of Plymouth: with 
respect to the latter, he acknowledges himself indebted for many 
valuable informations about the treatment of sick seamen to Dr. 
*Hammick, one of the principal medical officers of our navy. 
At Plymouth the most interesting work described by our au- 
thor is the break-water conducted by Mr. Widby under the in- 
spection and upon the plans of Mr. Rennie. This description, 
already published in French, translated into English, and received 
with a merited favour by the public, will be found considerably 
improved in this volume, to the end of which we are at last 
arrived. 
The naval part is accompanied by a dozen large drawings beau- 
tifully engraved, and representing with the greatest nicety the 
architectural or naval works and machines described in the.two 
volumes. 
Such is the great variety of interesting information collected 
by Mr. Dupin, that we have only been able in this account to 
indicate the principal heads of the most interesting objects com- 
prised in his descriptions. 
No doubt persons well conversant with the subject will find 
some inaccuracies or mistakes in various parts of the two vo- 
lumes which we have reviewed ; but we can say with the learned 
critic of Mr. Dupin’s military part in the Quarterly Review*, far 
from being astonished by such mistakes, or inadvertencies, we 
must only wonder how they are so few in number. We suspect that 
but few officers either of our army or navy have acquired so ex- 
tensive, deep and accurate knowledge of our military institutions, 
studies and works, as this intelligent foreigner exhibits.
