able mathematicians, and thus greatly enlarging the boundaries 
of useful science. 
As a Teacher, too, his labours have been singularly success- 
ful, especially as Professor of Mathematics for nearly forty years 
in the Royal Military Academy at Woolwich; an Institution 
which, by his judicious plaus and unremitting care, he raised to 
the highest degree of celebrity and national importance. To his 
instructions, indeed, and his improvements in Military Science, 
his country is deeply indebted for the superiority and success of 
the British Artillery and Engineers, in every part of the world, 
for the last half eentury. 
Such are the important objects to which Dr. Hutton has con- 
stantly devoted his valuable time and talents: and such are his 
well-founded claims to the gratitude and admiration of every 
lover of science,—claims which must ensure to him the lasting 
fame of having been one of the most efficient promoters of ma- 
thematical knowledge in any.age or country; especially in im- 
proving and simplifying those sciences which are conducive to great 
public utility. 4

man, though now in his eighty-fifth year, is still an ardent, and 
occasionally an active promoter of Science.

A Model of the intended Bust is already completed, and is 
considered a very accurate likeness. It may be seen at the Sculp- 
tor’s premises, No.37, King-street, Edgware road. Casts of 
the Bust, at two guineas each, will be prepared for such friends 
of Dr. Hutton as may choose to order them: but the Marble Bust 
is to be given to the Doctor himself, with the hope that he will 
hereafter present it to some Scientific Institution. 
NEW SHOWER BATH. 
To Dr. Tilloch. 
Srr,—lI had been long convinced of the danger to be appre- 
hended from the use of the common shower bath in particular 
diseases incident to humanity or delicate constitutions. The sud- 
den death of Mr. Spratt, at Brighton, from the shower bath, is a 
verification. ; 
Impressed with this conviction, I described an invention wherein 
the water was suspended by the resistance and upward Pie.
