been pretty generally attributed to a want 
of this fubffance; and that this actually 
takes place in many inftances cannot be 
eontroverted ; fo that a tranfparency of a 
bone is in general a fure fign that the per- 
fon to whom it belonged was ricketty. In 
confirmation of this opinion it may be ob- 
ferved, that the period in which children 
are moft expofed to the difeafe is precifely 
that in which there is the greatef{ demand 
for phofphat of lime for the procefs of offi- 
fication, that is, from the age of fix 
months to two years. 
However plaufible this theory may be 
{the author adds), it is not admiffible in 
thofe cafes in which the difeafe is caufed 
by the developement of any other acid, the 
action of which is directed to the bones, 
end particulsrly-in thofe rare but unquef- 
tionable catés where gout is complicated 
with rachitis. Such cates are mentioned 
by Morgagni and Portal; and lately Dr. 
Pinel has obferved, in the Bicetre, an old 
man of feventy, attacked with a gouty ef- 
fufion of calcareous matter through the 
fkin, which wes followed with a foftening 
of the bone, It would appear, at firlt 
fight, impoffible that thefe two difeafes 
fhould exift at the fame time, fince, on the: 
ove hand, rachitis is attributed to a want 
of calcareous phaofphat, and gout to its 
excefs ; but this apparent contradiction 
may eafily be reconciled. For, in a mol- 
kities offium, we cannot firictly conclude 
that a want of calcareous phofphat is felt 
in thewhole fy tem, but merely in the bones. 
Therefore, after an atony of the. veffels 
which ufuaily carry this earthy falt to the 
bones, may not it deviate from its ufual 
courfe? Then, it will be diverted to the 
‘fkin by tran{piration, as in the cafe of the 
old man in the Bicetre, aid produce an 
earthy exfudation; or it will be thrown 
upon the coats of the blood-veffels, the 
pericardium, or the heart, and occafion an 
offification ; or it will pafs to the kidnies 
and ‘urinary paflages, which is the moft 
common occurrence.

upon different parts of the fyftem, it is 
poflible that it may také its courfé' to the 
joints, and there’ produce anchylofes, fi- 
‘milar to thofe of the gout; and if this ef- 
feet is merely owing to a wrong direftion 
of the calcarecus matter, it will be fol. 
lowed by a foftening of the bone; a com- 
bination of fymptoms which has been de- 
fignated by the term arthvitic rachitis. «
