Sivu 362 - ... of the fundic portion. These slight variations are, however, of no fundamental importance, for they do not signify that the glands differ in character. All of the gastric glands are unbranched, flask-shape structures. Never have I been able to find the bifurcated forms described by Peterson ('09). He believes that the neck cells of the gland are of a rather primitive character during their early history, and that they may give origin to a side bud which with further differentiation, gives to...

Sivu 304 - This process of scientific inquiry involves peculiar qualifications which can not be disregarded by any one who thinks of trying it. Research implies in the first place seeking again over a region which has been previously traversed in order to learn what other men have done and the point where their labors ended. To make progress sure, therefore, previous records must be carefully studied. The failure to [ pay this just tribute to those who have labored before has not seldom led to fruitless effort...
Sivu 373 - Maurer believes that De Meuron described correctly the origin of the postbranchial bodies, but that he has confused their later development with the epithelial derivatives of the pouches, which come to lie near the thyreoid.
