Your commissioners have assured themselves of this by the examination of bodies prepared by M. Gannal, but not wishing to report on their own judgment, and in order to obtain a full conviction of the practical utility of the process, it determined to consult those persons who were continually occupied in dissection. Their opinion was unanimous. Among the experiments or applications of which the process of M. Gannal, has been the object, we shall place in the first rank the series of facts observed by our honourable associate M. Serres. The following are the details which he has transmitted to use on this subject. “In the month of June, 1836, in the amphitheatre of the hospital, the body of a man twenty-two years of age was injected. Abandoned to the open air, in a cabinet exposed to the south, and upon a wooden table, it was preserved until the month of September, and it ended in becoming mummified. “In the month of July, eight bodies were injected for dissection, each during fifteen days. “During the months of August and September, sixty subjects were injected; these were preserved for twenty days. “From these experiments, adds M. Serres, it results that the liquid furnished by M. Gannal preserves bodies to a certain extent: “1. Permitting their dissection during summer, a thing which has not been accomplished heretofore in the anatomical school of the hospitals. 2. Permitting to give to the instruction of operative medicine a development which, up to the present period, it had not enjoyed; for, during the months of August and September, we were enabled to preserve, as in the middle of winter, thirty bodies at a time on the tables, enabling us to repeat to seventy pupils all the operations, in following a regular course, previously impossible.” To this series of observations, already so decisive, we shall add the intelligence furnished us by different anatomists well known to science. Thus M. Dubreuil, the honourable dean of the faculty of Medicine of Montpelier, hastened, in the interest of anatomical studies, to make the necessary trials to assure himself of the efficacy of the process in question. During the spring of last year, the first body on which he operated was preserved for forty-one days, and the experiment was terminated without any thing announcing putrefaction. On a second body the result was the same, although it was chosen under the most unfavourable conditions. M. Bougery, who, it is known, is occupied in the publication of a great work on anatomy, declares that this process has very well succeeded in his hands, and that it has been very useful to him. In summer he injected two subjects which were preserved for three weeks; in winter, he injected a third, and this, although kept in a room heated to 15°, was preserved for seven weeks.
