Abstract

Several investigators have made reports upon the structure of the excretory system of the Gryllus domesticus. Bordas, 1899, presented work on the Gryllus domesticus, while Stuart (7), presented work on the Melanoplus differentialis. The present work is based primarily on the work of the two above named workers. There are no discrepancies to be reported here on any previous works, but rather, this investigation tends to prove that the structure found in the malpighian tubules of the Melanoplus differentialis is similar to those found in the Gryllus domesticus.

Many of the methods in microscopical techniques have been handed down tradition-wise from one investigator to another. Some methods used today are the results of accumulated experiences of several generations of work.

The work embodied in this investigation was done in the biological laboratories of Prairie View A. and M. College, Prairie View, Texas, under the supervision of Professor Thomas P. Dooley. I am pleased to express my appreciation to Dr. Dooley for the facilities afforded to me along with the kind criticisms of encouragement leading me to adopt the title chosen for this investigation.
