Chronic Laminitis , and also national Treatment based on this 
Theory , by M. G. Fogliata. —The author considers as erro¬ 
neous the prevalent idea that the gradual displacement of os 
pedis is produced by a mass of newly-formed horn inter¬ 
posed between horny and sensitive laminae. He thinks that 
this is not the order of things. It is not that the horny tumour 
forces os pedis out of place, but the reverse. Inflammation 
has destroyed, to a certain degree, the intimate union of 
horny and sensitive laminae, and os pedis, not being soundly 
supported, alters its position, and consequently new horn 
forms between the tissues. The horny tumour is the effect 
not the cause of separation. But why does the bone 
alter its position ? M. Fogliata insists that the bone does 
not descend; strictly, it simply undergoes rotation on its 
transverse axis; the toe of the bone only descends, while the 
basilar and retrossal processes rise. This being allowed, we 
can see that a certain rearrangement of the bony rays of the 
limb (phalanges and metacarpals or metatarsals, as the case 
may be) tends to bring the weight of the body on the coronal 
process to a considerable degree, correspondingly relieving 
the remainder of the articular surface of the third phalanx. 
Os pedis being unsupported, therefore, yields to this tendency 
to rotatory movement. The next question is, What could 
prevent this ? Extensor pedis could do so, but that muscle, 
powerful as it is, cannot be compared with the flexor perfo- 
rans, which is of greater volume and singularly favorably 
inserted. While these conditions are combining to bring 
about displacement, the inflammation which has led to sepa¬ 
ration of the horny and sensitive laminae ensures a secondary 
and serious condition—the formation of the horn tumour. 
The author thus attributes the greater number of these 
effects to the action of the perforans, and suggests a remedy, 
plantar tenotomy. He has made some experiments which 
confirm the value of this method, and recommends it to his 
brother professionals as w^ell worth a trial, considering the 
uselessness of other means {ibid ). 
On Tetanus, by Dr.MoLLER.—Billroth having expressed an 
opinion that tetanus is perhaps a blood disease, Dr. Moller 
determined to try some transfusion experiments with the 
blood of a tetanic animal. These experiments, five in 
number, were made at the Berlin Veterinary School. Trans¬ 
fusion was made from horse to horse of defibrinated blood, 
in quantity varying from 300 to 500 grammes. This was 
done by means of a Pravaz syringe of large size, capable of 
containing 500 grammes of blood, with a strong, perforated, 
sharp nozzle, 1*5 mm. to £‘5 mm. in diameter, with an
