It occurred to me that as the tubes and their plexus of capillaries were probably, for reasons presently to be stated, the parts concerned in the secretion of that portion of the urine to which its characteristic properties are due (the urea, lithic acid, &c.), the Malpighian bodies might be an apparatus destined to separate from the blood the watery portion.
الصفحة 293 - In the interspaces of the fixed teeth in both these bones, the places of attachment of the shed teeth are always visible ; so that the dental formula, if it included the vacated with the occupied sockets, would express a greater number of teeth than are ever in place and use at the same time.
الصفحة 294 - The superior maxillary bone diminishes in length with the decreasing number of teeth which it supports : the transverse or external pterygoid bone elongates in the same ratio, so as to retain its position as an abutment against the shortened maxillary, and the muscles implanted into this external pterygoid...
الصفحة 152 - John Hunter similarly regarded it, after independent examinations of the organ, stating that " a small portion of it (the prostate) which lies behind the very beginning of the urethra, swells forward like a point, as it were, into the bladder, acting like a valve, to the mouth of the urethra.
