We may remark, that under no circumstances were long and deep scarifications made on the trunk or members, in order to allow the liquid to penetrate the thickness of the tissues. The cranium itself was not opened, nor was there any application of the trephine, in order to permit a more ready entrance of the liquor to the meninges, or to the brain itself. Nevertheless, after more than two months immersion in the liquor, the brain, extracted from the cranium, if it could no longer serve for new researches on its structure, might have been employed for demonstrations. But, for how much longer time could this preservation be continued? What temperature is it capable of resisting? And what expense does it require? In fine, can the discovery be extensively applied? That is to say, is it possible, by this process, to preserve a great number of subjects during summer, to deliver them later to the students during the season of dissection? And if these subjects, thus preserved, exhale no odour, become in no manner a cause of insalubrity, or of danger to the students, for the anatomists themselves, or for the persons who inhabit the houses adjoining the anatomical amphitheatre, might not the dissections be indefinitely prolonged, in place of permitting them only during the rigors of winter? In fine, has this saline liquor of M. Gannal preservative properties sufficiently pronounced to be employed during long voyages, and in hot climates, for the purpose of bringing home numerous animals of large size, to serve for the study of comparative anatomy? The small volume which saline substances occupy, and the sea water, which might serve to make the solution of the salts in any quantity as soon as needed, would be circumstances favourable to the use of this process. In order to answer all these questions, it would be requisite to multiply the experiments, to extend them during a much longer period, and upon a very great number of subjects. These experiments, directed in this spirit, would exact expenses which we thought ought not to be imposed upon the author of the process for the preservation of dead bodies, who has already been subjected to a multiplicity of demands, for the reimbursement of which we propose an indemnity from the Academy, without prejudice to the recompense which M. Gannal may have a right to claim, when the experiments shall have received that extension which we wish to be able to give them. However this may be, we thought, in this provisionary report, that we ought to call the attention of the Academy, and of superior authority, to the process of preservation discovered by M. Gannal, and we manifest the desire that a sum be awarded to him as an indemnification for expenses already accrued, and in order to facilitate the means of continuing his experiments on a large scale. We shall add that this process of preservation may be very advantageously applied to various cases of legal medicine. _Paris, 16th June, 1835._
