Your duties

Never loose a lecture. Experiments cannot be repeated. You cannot possibly get the same knowledge from the lectures of an other.

Knowledge taken in by the eye-this is durable. No excuse taken for absence which will affect standing-excuse refers to the college. Loss your misfortune.

Bring friend with you.

Another point punctuality. 5 minutes by the clock given-complaint about hanging about the door can come in a few minutes before time.

Attendance in the afternoon also important additional explanations given. Recitations-not so much to determ the standing of the individual as to find out the points not well understood by the class.

All absentees will be examined seperately on the lecture.

Those that come early must refrain from handling the apparatus. Attention is a faculty of the mind which can be much improved. To learn to receive instructions orally is important.

To insure attention notes should be taken.
 I must insist on notes being written out of the lecture room on the lectures.

I have consulted the best men in every class and they all inform me they have derived great benefit from taking notes.

From notes in the room fill out leave every other page for additions & corrections. I will exam the books every week.

During the time I have the class I will almost always be in the room from 2 until four to
answer questions &:
Your class does not come to me with a very high character for intellect.

You are of goodly bodily proportions with some exceptions-and I venture to say that your minds of the ordinary stamp.

I do not put much trust in particular genius. Give me a mind of general powers not deficent in any one faculty and we have the elements of a great mind.

This is the 15th class. I have not found a genius among the whole number if you mean by genious the power of developing knowledge by spontaneity without study.

What ever is worth possessing must be purchased at the expense of labour. The Gods have placed a price on that which is valuable.
