SUMMARY The absorption of d‐xylose forms the basis of a useful screening test in the investigation of small intestinal disorders in the horse. A comparison has been made of different assay methods and there was no significant difference between the results obtained with the parabromoaniline (PBA) method or the ferric chloride‐orcinol (FCO) method. The orthotoluidine method was unsatisfactory. The anticoagulant agent did not affect the test. A dose of 0.5 g commercial grade xylose/kg body weight as a 10 per cent solution given by stomach tube, produced a peak plasma xylose level after 90 min and should discriminate normal from abnormal absorption. The FCO method was preferred for the occasional test performed in practice, and a 2‐hour sampling period would be adequate. RÉSUMÉ L'absorbtion du D xylose, constitue la base utile d'un test permettant d'apprécier les troubles de l'intestin grěle chez le cheval. Une comparaison est faite des différentes méthodes et les RÉSultats obtenus ne diffèrent point d'une fačon significative lorsqu'on utilise la méthode de para‐bromoaniline et celle du chlororcinol ferrique. La méthode à l'orthotoluidine ne fut pas satisfaisante. L'anticoagulant utilisé ne modifia point les RÉSultats. Le xylose à raison de 0,5 gramme par kilo de poids vif, est administréà la sonde naso‐oesophagienne. On obtient un niveau maximum de xylose dans le plasma apRÉS 90 minutes, ce qui permet d'apprécier les anomalies d'absorption. Le test au chlororcinol ferrique a paru plus adaptéà la pratique. ZUSSAMMENFASUNG Die Absorption der D‐Xylose kann als nützlicher Screening‐Test bei der Untersuchung von Dünndarmstörungen beim Pferd verwendet werden. Es wurde ein Vergleich angestellt zwischen verschneidenen Bestimmungsmethoden; es fand sich keine signifikante Differenz zwischen den Resultaten, die erhalten wurden mit der Parabromanilin‐Methode oder mit der Ferrichlorid Orcinol‐Methode. Die Orthotoluidinmethode dagegen erwies sich als unbefriedigend. Das verwendete Coaguans beeinträchtigte den Test nicht. Eine Dosis von 0,5 g Xylose pro Kilogramm Körpergewicht in einer 10%igen Lösung wird durch die Nasen‐schlundsonde eingegeben; 90 Minuten nach der Gabe wird der Gipfel der Plasmakonzentration erreicht, was die Unterscheidung einer normalen von der abnormalen Absorption erlaubt. Die FCO‐Methode wurde für einen gelegentlich in der Praxis durchzuführenden Test bevorzugt, wobei eine 2stündige Entnahmeperiode genügen dürfte.

Six years ago we read a paper before you on ‘Recent Discoveries in connexion with Roman London’, when you kindly gave us leave to make further researches on behalf of the Society. Since then we have been almost constantly watching excavations in London, and it is now our duty to give an account of Roman remains exposed to view since June, 1906. It will naturally be asked why we have delayed so long: the reply is, that these diggings have followed each other in rapid sequence, lasting in some cases over protracted periods and demanding much sacrifice of time and energy. A large part of our observation also has met with little definite result, while frequently later finds have had a bearing on those which preceded them, and have thus offered opportunities of correcting and amplifying the previous records.

Early in January, 1905, the street called London Wall was opened by the Post Office authorities for the purpose of laying telephone mains. Operations were begun at Moorgate Street and were carried in an easterly direction, a deep trench being dug in the middle of the roadway. The excavations had extended past Salisbury House as far as Circus Place, when it was noticed that among the débris thrown at the side of the road were quantities of ragstone and Roman tile, showing clearly that the city wall was being cut into.
