PKOCEEDINGS OF SOCIETIES. 87 



Mr. T. Cliarters White read a short communicatioii "On Phy- 

 cocyan." 



The thanks of the meeting were given to Mr. "White. 



Mr. Shiek read a paper '• On the employment of Colloid Silica in 

 the preparation of Crystals for the Polariscope." 



The thanks of the meeting were presented to Hj. Slack. 



Ml". B. T. Lowne read a paper " On the Anatomy of Ascaris lum- 

 bricoides." 



The Chairman at the conclusion of the paper testified his sense of 

 the great care, minute observation, and accm-ate delineation displayed 

 by Mr, Lowne in his communication. 



Dr. Braithwaite congratulated the Society on the inauguration of 

 the new year by the remarkable paper just read, which he considered 

 one of the most valuable ever presented to the Society. 



Dr. Lawson concm-red in these remarks, and observed that so many 

 new facts and views had been recorded by the author that it would be 

 utterly impossible to comment on them then. He thought the author 

 merited the best thanks of the Society for his eftbrts. 



The Chairman, in proposing a vote of thanks to Mr. Lowne, ex- 

 pressed the hope that he would continue his investigations, and favour 

 the Society at some future period with the results he might obtain.' 



Mr. Hogg suggested that any Fellow who should meet with the 

 entozoon described should send it to Mr. Lowne. The subject was 

 an important one in a medical point of view, and much light might be 

 thrown upon it by inquiries such as those Mr. Lowne was conducting. 

 In medical practice it not unfrequently happened that cases similar to 

 that mentioned by him were brought under the notice of the practi- 

 tioner, in which Ascarides foiTued a prominent feature in disease. He 

 (Mr. Hogg) had had children repeatedly brought before him in order 

 that a horrid squinting might be corrected, in whom there were cer- 

 tain indications that Ascarides was the cause of the disease ; and he 

 had not long ago seen a child, between five or six years of age, from 

 whose mouth Ascarides had been observed to crawl, thus coufii-mincr 

 the statement made by Mr. Lowne. He believed that Mi-. Lowne 

 had cori'ected some erroneous impressions which were cm-rent in 

 regard to these animals. Eegarding the investigations so ably con- 

 ducted by Mr. Lowne, he (Mr. Hogg) could not help wishing that in 

 this country, as in some Continental nations, men of such original 

 powers of research were enabled, thi-ough provision made by the 

 Government for the purpose, to carry on their labours, undistiarbed 

 by the harassing cares of an arduous profession. 



The thanks of the meeting were then given to Mr. Lowne. 

 Lq acknowledging the vote, Mr. Lowne took occasion to remark on 

 one point on which he had touched in his paper, that as yet we did 

 not know how the embryonic forms of Ascaris got into the intestinal 

 canal. He had also observed, contrary to the experience of some 

 writers on the subject, that the yelk segmentation was to be seen in 

 the egg while still in the body of the animal. According to Dr. Cob- 

 bold and some German authors, this never took place until after the 

 egg had been soaked for a long time in water. He (Mr. Lowne) had 

 found the yelk segmentation without subjecting the eggs to this pro-
