THE analysis of the Human Fluids, accordingto the laws of modern chemistry, has been, forsonae time, a desideratum in medicine; but uiatillhe present publication, no writer has exhibited a complete vieta of the subject. The great experience of the learned Author. frona his siluation as Public Profestar of Chemistry, and the luminous order and perspicuity whicli isseen in every part of the folio ing Treatisse, Cannot but render it extensively usesul in a chemicat

PREFACE BT THENo writer ever possessed, in an higher degreethe spirit os analysis richin matter, and concise in description, he every where uni olds to his readers, with perspicui ty and order, the nature and qualities of the subject ori Which he treals. The subsequent Work is principalty designed asa compendium, Or teXt-book, to the more elaborate labours of modern chemisis, Who have, in
pari oraly, examined the properties of sonae par- liculur fluids of the body; but it is to be hoped, that it may further excite physicians, to elucidate the nature and ossice of the animal fluids, by this mode of analysiis, and lead to a Clearer conceptionos the Animal inconomy. I Uill also serve as an ut ei ut introduction to the
generat palliology the respectabie profestar promises ; Whicli is likely to prove of great utility in the praetice of medicine.

AUT HOR. CHEΜISTRY teaches, iliat the Fluids constitute by far the largest part of the human body;
and the consideration of them, vitii regard lo
their disserent ossices in the Animal inconomy, is
not a less important part of physiology, than thedoctrine of the solids themselveS.
Hence I am os opinion, that it xviil be of the greatest utility to estabiisti a doctrine, which saali specialidi consider the fluid of every solid pari; more es pecially, as the modern analysis of the Human Fluids, hicli deservedly gains groundover ille antiphlogistic chemists of the present times,) uni olds far disterent and more certain principies than were ever known to the chemisis

It is to be lamented, that, even in the presentday, very few of the fluids of our body have been examined on the principies of modern chemistry ;when there is the greatest reason to supposie, that both modern physiology, and palliology Would receive considerable lighis and improvemenis fromtheir application This Chemico-Physiological attempt in tabellary-compendium, mews how sar this science hasbeen carried in the healthy itate.
