INTRODUCTION.

Whatever may be the position of British pharmacists in comparison with

those of other countries, it cannot be said that they have paid the

attention to the analysis of urine which the subject has received from

pharmacists on the Continent. Considering the importance of the

subject, this curious neglect can only be attributed to the fact that

the pharmacist in Great Britain is but slowly attaining the position

of chemical expert to the physician, which his foreign _confrere_ has

so long held with credit and even distinction. In France, for example,

M. Méhu, whose name is familiar to readers of this journal, is looked

upon as one of the leading authorities on morbid urine and its

analysis, and yet a list of goodly pharmaceutical papers shows that,

as the medical analyst, he has not forgotten his connection with pure

pharmacy.

There are several points about urinary analysis which entitle it to a

very high position in the estimation of pharmacists. In the first

place, the physician is no more likely to be fonder of the test tube

than of the pestle, of analyzing urine than of compounding his own

medicines. Leading men in the profession are more and more setting

their faces against the dispensing doctor, and there are numbers among

them who admit that they succeed no better as analysts than they do as

dispensers.

Some old fashioned practitioners trouble themselves very little about

their patients' urine, except, perhaps, in respect of sugar and

albumen. On the other hand, numbers of leading physicians, including

especially those highly educated gentlemen who cultivate a consulting

practice, are in the habit of pushing urinary analysis almost to an

excess. One well-known specialist of the writer's acquaintance, with

an extensive West End practice, makes quantitative determinations of

urea, uric acid, and total acidity, in addition to conducting other

diagnostic experiments, on every occasion that he interviews his

patients. By this means he has accumulated in his case books a mass of

data which he considers most valuable as an aid to diagnosis, and

through that to successful treatment.

Pharmacists are proverbially neat-handed, as Mr. Martindale would say,

and their habit of conducting dispensing operations which involve the

dexterous manipulation of very small quantities of material fit them

admirably to undertake volumetric and other rapid analytical

determinations. Compared with the doctor there is no doubt that in

this matter the chemist is _facile princeps_, and from the nature of

their respective occupations such could only have been expected. A few

chemists throughout the country lay themselves out to save their local

doctors from unwelcome test tube practice, and these almost to a man

find it pay. Some charge a handsome fee to patients, and a small one

when the analysis comes through the physician. Others find it to their

interest to furnish medical men with qualitative reports on sugar or

albumen gratuitously. Although this practice has certain obvious

drawbacks, if a doctor sends his prescriptions to a chemist, the

latter is often willing to gratuitously perform his chemical work. In

the present article we propose to describe briefly but fully the

methods which have been found of most value in practice.
