LECTURES IN THE 
PHILADELPHIA COLLEGE OF PHARMACY. 
Thirty- first Session of the School of Pharmacy, 1851-52. 
The Lectures in this institution will commence on Thursday, October 16th, 
and terminate about the middle of March. They will be held in the Hall 
of the College, Zane street, on Tuesdays, Thursdays, and Saturdays, two 
lectures each evening at 7 and 8 o'clock. 
Robert Bridges, M. D., General Chemistry. 
William Procter, Jr., Theoretical and Practical Pharmacy. 
Robert P. Thomas, M. D. ? Materia Medica. 
The lectures on CHEMISTRY will embrace in a systematic view the laws, 
operations and results of this science, and its relations to Pharmacy. The 
elements concerned in inorganic nature, and their compounds, will receive 
such notice as their relative importance in this respect demands ; and will 
be illustrated by experiment, diagram, specimens, and processes. 
Organic chemistry will also receive its full share of attention, and all its 
compounds, possessing general or pharmaceutical interest will be brought 
under consideration in a similar manner. 
The lectures on PHARMACY will treat, of the elementary operations 
required in the preparation of medicines; viz., weights, measures, and 
specific gravity, the management of heat, the manipulations in the processes 
of pulverization, solution, evaporation, distillation, crystallization, &c. ) all 
illustrated by the most approved models, diagrams and apparatus. 
The pharmaceutical preparations of organic drugs will be considered as 
follows; viz. The simple preparations of each drug will be noticed under 
the head of that drug, and each compound preparation under the head of 
its chief constituent. Each class of preparations as tinctures, extracts, 
plasters, &c, will receive a general notice in its proper place. The classifi- 
cation of the subjects will be in groups founded on the nature of their chief 
constituents; these may be starch, gum, sugar, resin, volatile oil, fixed oil, 
tannin, alkaloids, etc., each group being prefaced by a general description of 
the principle or principles giving it name. The preparations of each drug will 
be preceded by such notice of its chemical constitution, as will exhibit the 
kinds of treatment best calculated to extract and preserve its active portion. 
The course will conclude with the processes for those inorganic chemicals 
which may be prepared by the apothecary himself, when desirable, without 
any reference to their systematic chemical relations. 
The lectures on MATERIA MEDICA will be exclusively devoted to vege- 
table and animal substances, their origin, commercial history, characters, 
composition, and medical properties, together with their adulterations and 
the means of detection. The course will be commenced with three lectures 
on the elements of botany, and will be made practical and demonstrative by 
the exhibition of an extensive collection of the substances, their varieties 
and falsifications, aided by accurate drawings, and a full series of exotic 
and indigenous plants in their dried state. 
Experiments illustrative of the proximate organic principles and modes 
of their detection, with the difference between genuine and spurious articles, 
will be introduced whenever deemed interesting or important. 
Qualifications for Graduation. — Every person upon whom a diploma 
of this college shall be conferred, must be of good moral character, must 
have arrived at the age of twenty-one years, have attended two courses of 
each of the lectures delivered in the college, or one course in the college,
