The inferior peduncle of the cerebellum was accordingly divided on one side, the organ itself and its other peduncles being otherwise left intact, and the results obtained by this procedure were controlled by experiments in which the lateral tracts of the medulla oblongata were divided on one side without injury to the pyramid on the one hand or to the posterior columns and their nuclei on the other. Further control experiments consisted in dividing transversely the posterior columns and their nuclei a few millimetres above the calamus scriptorius, on one side, without including the lateral tracts of the medulla in the lesion.","PeriodicalId":20661,"journal":{"name":"Proceedings of the Royal Society of London","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1098/rspl.1896.0038","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49385526","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

F. of the current of rest of the skin of the Fish is entirely due to mucin-metamorphosis, and that it is not possible to attribute it to the presence of glandular elements is negatived, in the case of the Eel, by the absence of any such mucinous change in the superficial epidermic cells and by the presence of abundance of secretory cells throughout the structure. 2. The existence of considerable differences of potential between two contacts upon the outer surface of the skin, and the fact that such E. M. F. is capable of excitatory augmentation upon mechanical stimulation, coincides with the assumption that the E. M. F. of the current of rest is the outcome of glandular processes of variable activity and is not compatible with the theory of origin of the E. M.

As the experiments were on one man, I have taken an opportunity of repeating them on another person; and as the late observations of Dr. Austin Flint (junior) on a man who walked 317 miles in five days have appeared to some persons to run counter to the now generally accepted view that exercise produces either no change or only insignificant changes in the urea, I have combined experiments on exercise with those on alcohol. With respect, however, to Dr. Austin Flint’s experiments, it would appear that while the egress of nitrogen was determined with the greatest accuracy, the amount taken in was for the most part merely estimated by reference to Payen’s Tables, and therefore there is no certainty that the ingress was what it is assumed to have been. The food also was very varied, so that the difficulty of properly estimating the nitrogen was still more increased. The following experiments were made on a soldier, W. D., aged 30. I He is a powerfully built man, 5 feet 6 inches in height, and measuring 40 inches round the chest. As a young man, he had been employed in a distillery near Glasgow, and at that time drank largely of whisky, some times taking half a piut before breakfast. For the last ten years, since he t has been in the army, he has been very temperate, taking chiefly beer in moderate quantities, and only occasionally spirits. He bears the character of a very steady soldier, and has always had perfect health, with the exception of an attack of “spotted typhus” six years ago. He has never served abroad.","PeriodicalId":20661,"journal":{"name":"Proceedings of the Royal Society of London","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1098/rspl.1871.0076","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"62205348","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The forces which presented themselves at these distances are to be attributed mainly to a true Crookes’s reaction between the disks ; and they seem to warrant the conclusion that Crookes’s reaction was manifested at a dis­ tance of at least 10 millims. in a hydrogen vacuum, when the outstand­ ing tension was as much as 5 millims. of mercury. At distances of from 20 to 80 millims. the very feeble force acting on the glass disk in our apparatus seemed to vary about inversely as the tension. As already mentioned, it appeared to be nearly independent of the distance when the distance exceeded 20 millims. _ At distances of 5, 10, and 20 millims. the force on the swinging disk made some approach to varying at each tension inversely as the distance.
