    liave before us, not only that which harmonises with what is susceptible of recognition as occurring in the vegetable kingdom, but that which agrees with the resultant phenomena of life in the animal kingdom made manifest to us by common observation. If carbohydrate matter becomes applied, as I hold it does, to fat- and proteid-formation the position assigned, no opportunity is given for its reaching the general circulation and thence the urine. If ingested and not so applied, however, it follows that some- thing else must ensue, and the something else seeu to occur is passage into the general circulation as sugar and subsequent elimination as unutilised material with the urine. Thus we have the glycosuria associated with alimentation satisfactorily accounted for. In connection with the glycosuria of tissue origin, things stand on an equally intelligible footing. The carbo- hydrate matter, the primitive source of which is in the vegetable kingdom, contained in our food is regarded as being in part synthesised into proteid, the basis of our tissues. Being simply locked up under the form of a glucoside, it is ready to be liberated whenever exposed to the requisite influence for bringing the result about. Nothing further than the presence of a suitable ferment is needed to provide for the eliminated sugar taking its origin from the tissues. But Dr. Paton says at the end of the passage quoted that the existence of a carbohydrate element in the proteid molecule cannot be accepted. He has
