SCHOOL OF APPLIED CHEMISTRY, 
Attached to the “ Department of Philosophy and the Arts,” 
in Yale College. 
H3a ©OtLtLQBOAlislp D[r3 
Professor of Chemistry and the Kindred Sciences Applied to 
the Arts. 
3a Pa KIQKTT©^ 
Professor of Agricultural Chemistry. 
THE Instructors in this Department have opened a commodi¬ 
ous Laboratory on the college grounds, where they are now pre¬ 
pared to receive pupils in Special and General Chemistry. The 
system pursued with those who design to become chemists, or to 
study the science extensively, is thorough and complete. Such 
students always commence with an extended course of qualita¬ 
tive examination of unknown substances—and in due time pass 
through a series of varied quantitative determinations. To those 
who wish to follow special investigations connected either with 
the arts, agriculture, or pure science, every facility will be afford¬ 
ed, both in organic and inorganic analysis. 
rrof. B. Silliman, Jr , will instruct particularly in general Ele¬ 
mentary and Analytical Chemistry, Mineralogy, and Metallurgy, 
with special reference to their application to the useful arts. He 
will also give a course of Leciures on Mineralogy and Metallurgy, 
continued through the summer term. During the fall and earlier 
part of the winter, he will also carry a class through a course of 
Elementary Chemistry, in elucidation of the regular course on this 
subject in the academical department. 
The instruction in the professorship of Agricultural Chemistry 
is intended to unite, as much as possible, practical views with 
theory; to give the untaught farmer an opportunity to become 
acquainted with so much of science as shall enable him to reason 
upon his daily pursuits, and to understand the great principles 
upon which good cultivation must depend, presented in so plain 
a form, as to be within the comprehension of all. Few chemi¬ 
cal terms will be employed in the lectures, and those only of the 
simple explanations ; they will thus be understood by those who 
have never devoted any attention to the subject. \ regular course 
of lectures will be delivered in the winter of each year, commenc¬ 
ing in January and continuing about two months, there being 
four lectures in each week. The subjects of the course will be 
—the composition and nature of the soil, the plant, and the ani¬ 
mal—theories of rotation of crops, and of feeding—modes of 
draining—the different kinds of manures, their value and how 
beneficial—the improvement ot waste lands, &c., &c. Text 
books will be indicated for study during leisure hours. 
In connection with the lectures will be a short course of Ele¬ 
mentary Chemistry, for such as wish to study somewhat more of 
chemistry than is given in the course, and to qualify themselves 
for making ordinary testings and qualitative examinations of 
soils, manures, &c.; this course will occupy two hours of five 
days in each week during two months. 
The fee for the lectures on Agricultural Chemistry will be $10. 
That for the elementary chemical course, including apparatus 
and reagents, will be $25. 
Students in Analytical Chemistry are allowed to work in the 
laboratory during the whole day ; glass will be furnished (with 
charges for breakage), also the ordinary reagents and balances 
for the use of those who are so far advanced as to require them. 
There will be frequent recitations, and the students will receive 
the constant attention of one or both of the professors The fee 
for this class will be $20 per month. 
The vacations will correspond with those in the academical 
departments, viz. :—six weeks from the third Wednesday of 
August; two weeks from the first Wednesday in January; and 
four weeks from the third Wednesday in April of each year. 
Sessions begin with the close of each vacation, and are at length 
respectively, 14—14, and 12 weeks. 
Students in this school will enjoy all the advantages to be de¬ 
rived from the extended means of the institution in libraries, in¬ 
struments. and collections. The mineralogical and geological 
collection is widely known as one of the best in the country, and 
there are smaller collections in the possession of the professors. 
Those who desire it, can have access to the Lectures on Chemis¬ 
try, Mineralogy, and Geology, by Prof. B. Silliman, Sen., and to 
the lectures on Natural Philosophy, by Prof. D. Olmstead. 
Instruction is also accessible in the higher Mathematics, in En¬ 
gineering and the use of Instruments, in Philology, History. 
Oriental Languages, and Belles-Lettres. 
The department of Philosophy and the Arts, in Yale College, of 
which-the school of Applied Chemistry is a part, has been orga¬ 
nized with a view to meet the wants of those who desire to fol¬ 
low the studies embraced under it farther than they are pursued 
in a collegiate course. Those who desire further information on 
this subject are referred to the annual catalogue of the Institution 
for 1847-M8. 
A college education is not required, however, of those who be¬ 
come students under this department. 
The professors are always accessible to those who wish to con¬ 
sult them on matters relating to their several departments; and 
will undertake such analyses and investigations as may be en¬ 
trusted to them. Letters of inquiry will be promptly attended to.

AMERICAN MUTUAL LIFE INSURANCE COM¬ 
PANY. 
Office No. 40 Wall Street, N. Y. 
LIFE INSURANCE, upon the plan adopted by this Company, 
is founded upon the principle of contribution in the shape of an¬ 
nual premiums to a common fund, proportioned to the amount 
insured, out of which the Company pay a stipulated sum on the 
death of the assured to the person for whose benefit the insur¬ 
ance is effected. 
After a thorough investigation of the different systems adopted 
in Europe and America, and of the rates of premium charged, 
this company have reduced the premium 25 per cent, payable 
in cash, annually, semi-annually, or quarterly, as may be pre¬ 
ferred, under a firm conviction that the exigencies of the Com¬ 
pany will never exceed and seldom require one half of the an¬ 
nual premium now charged by the English and American Com¬ 
panies, which reduction will still leave a large margin for seasons 
of unusual sickness and death among its members—preferring to 
reduce the premiums at once to an amount more nearly approxi¬ 
mating the actual necessities of the Company than to adopt the 
system of premium notes which is attended with many disadvan¬ 
tages. 
The leading features of this Company are— 
1. A guarantee capital of $50,000, which together with the ac¬ 
cumulating premiums is deemed adequate to meet every contin¬ 
gency. 
2. A reduction in the rates of premiums—payable annually, 
semi-annually, or quarterly, as may be preferred. 
3. The assured participate annually in the profits. 
4. Insurance may be effected by any married woman upon the 
life of her husband, for her sole use and benefit, free from any 
claims of the representatives of her husband, or any of his credi¬ 
tors. 
5. No personal liability of the members beyond the amount of 
their annual premium of insurance. 
6. Creditors may insure the lives of their debtors, or debtora 
themselves may insure for the protection of their creditors. 
A prospectus has been issued (which can be had at the office 
of the Company, or any of its agents), explanatory of the terms 
and conditions ofinsurance.
