The following instructions in regard to securing tickets for these lectures is given:

Admission to these courses is free, but only by ticket, the number of tickets being limited by the capacity of the hall.

Tickets are distributed to the public under the following rules:

1. Admission tickets to the first lecture of each course will be mailed, one to each applicant, in the order of application, and until the supply is exhausted, to all persons whose letters of application are received at least two days before the beginning of any course by the curator of the Lowell Institute, 491 Boylston street, Boston, and are accompanied by stamped, addressed, envelopes.

In such envelopes, when duly stamped and addressed, tickets will be mailed as soon as they are ready for distribution and if the supply is not already exhausted. If, however, as often happens, the desired tickets are not ready for distribution, the envelopes will be kept on file in the order of application, and, as a rule, tickets for any course will be mailed to applicants a few days only before the actual beginning of that course.

A separate envelope must be sent for each ticket desired.

When tickets are in great demand, only one ticket will be mailed to any one applicant or in any one stamped, addressed envelope.

2. Persons desiring to secure tickets for more than one course must send a separate stamped, addressed envelope for each ticket for each course.
