Mix together in a brazen vessel and place this in the sun during the dog-days. Put in a sponge to absorb the mixture, and then place the sponge in the sun until all the moisture has evaporated. When an operation is necessary, let the patient hold the sponge over his nose and mouth until he goes to sleep, when the operation may be begun. To awaken the patient after the operation, fill another sponge with vinegar and rub the teeth and nostrils with the sponge, and put some vinegar in the nostrils. An anaesthetic drink may also be prepared as follows: _R._ _Seminis papaveris albi et nigri, Seminis lactucae, aa. ounce I. Opii, Misconis ( , poppy juice?)_, aa. scruples I-II, as required. The patient is to be aroused as before. On folio 180d we find a chapter entitled "_De cathena gulae incisa vel fracta_," and copied almost literally from the chapter "_De catena gulae_" of Roger. In neither writer do I find any precise definition of what the _cathena gulae_ is, though Roger says, _Si es gulae, quod est catena, fractum fuerit_, etc., nor do I find the terms used explained in any dictionary at present available. The description of the treatment of this fracture seems, however, to indicate that the _catena gulae_ of Roger and Gilbert is what we call the clavicle, though the more common Latin names of this bone are _claviculus_, _furcula_, _juglum_ or _os juguli_. Gilbert says: "But if the bone which is the _cathena gulae_ is broken or in any way displaced (_recesserit_), let the physician with one hand raise the forearm (_brachium_) or arm (_humerum_) of the patient, and with the other hand press down upon the projecting portion of the bone. Then apply a pledget moistened with albumen, a pad and a splint in form of a cross, and over all a long bandage embracing both the arm and the neck and suspending the arm. A pad (_cervical_) should also be placed in the axilla to prevent the dropping of the arm, and should not be removed until the fracture is repaired. If the fracture is compound, the wound of the soft parts is to be left open and uncovered by the bandage, so that a tent (_stuellus_) may be inserted, and the wound is then to be dressed in the ordinary manner."
