    Oil the otiier hand we ourselves have found slight infiltration and a little thickening of the arachnoid and pia mater, but without false membranes on the dura mater. M. Ruge, for his part, has only observ- ed in the dura mater dilatation of the vessels, and in the pia mater simply injection or oedema. Whence arises this diversity in the results obtained by analogous experiments ? The cause seems to us to reside in the production of meningeal haemorr- hage in some animals during the drunkenness. Without wishing to raise here the interesting ques- tion of meningeal haemorrhages and consecutive false membranes, so often discussed since the time that M. Baillarger determined their precise seat in the arachnoid cavity,* we will remind our readers that M. Laborde by puncturing the superior longitudinal sinus in young dogs obtained extravasations of blood in the arachnoid cavity, which were surroimd- ed by a membrane of new formation as early as the tenth day. More recently M. Sperling,f operating on the rabbit, inje>2ted fresh blood into the arachnoid cavity. Eight days after the opera- tion, one observes the commencing formation of a new membrane which becomes completely or- ganized at the end of two or three weeks; in all eases, one can at the end of three weeks find a new formation of vessels. These new membranes are entirely analogous to those which one finds in haemorrhagic pachymeningitis.
