turns to these and at once learns how many specimens of this race, besides his 
own, have been collected and where they are located. He at once opens a 
correspondence with the proprietors of these collections, and is soon put in 
possession of any information which he may desire. 
Moreover, these catalogues would form an admirable basis for the interchange 
of duplicate crania, for the owners of them would know exactly where to apply 
to make up their deficiencies. The correspondence, also, to which the inter- 
change of catalogues and duplicate crania would give rise, would of itself 
greatly facilitate the progress of Craniography, by making the students of this 
science acquainted with each other, and enabling them by a private interchange 
of opinions to verify their conclusions or examine them in different points of 
view before publication. There can hardly be a doubt that the different col- 
lections would be respectively increased by the extensive distribution of such 
catalogues in the hands of army, navy, and other government officials, officers 
of merchantmen, travellers, naturalists connected with exploring expeditions, 
and others whose opportunities might be favorable to making such collections, 
and who would cheerfully do so were their attention once explicitly directed 
to this matter. 
Again, it appears to me that the progress of craniography might be very 
much and very readily facilitated by some such plan or system of co-operation 
as the following. Let all those actually engaged or interested in the study, in 
any particular country, notify the secretary, or appropriate officer, of the most 
prominent and best known scien Jific institution in that country, of the existence 
and precise location of any collection of crania with which they may be ac- 
quainted, no matter how small or imperfect such a collection may be, stating 
carefully the name and address of the Society or individual owning the collec- 
tion, the number of skulls contained, and the different races of men represented 
therein. Let the secretary or other officer receiving such communications 
cause them to be published from time to time in the printed journal, transactions 
or proceedings of the Society. These being sent in exchange or otherwise, to 
scientific associations and individuals in other countries, would thus become 
the vehicle for the transmission of this information to the craniographers of the 
latter places. 
The editors of scientific, medical and literary magazines, journals, reviews, 
&c., have it in their power greatly to promote craniographic science by insert- 
ing in their pages from time to time, and thus disseminating the information 
obtained in the manner indicated above. This statement particularly applies 
to medical Journals, inasmuch as most of those cultivating Craniography are 
physicians, not a few of whom are in the active public or private practice of 
their profession. 
These crude suggestions are offered to the Academy in the hope that, being 
distributed with its Proceedings, they may attract the attention and active sup- 
port of those who are interested in, and who are able and willing to advance so 
important a branch of the Science of Man,
